Reddit mentions: The best computer modelling books

Here's a bunch of resources for ya.

Start by checking out OpenTopography. They have data for free download as well as a great tools page:

https://opentopography.org/

​

For free software I recommend checking out:

Cloud Compare https://www.danielgm.net/cc/

QTReader http://appliedimagery.com/download/qtreader-64-bit/

and Fusion http://forsys.cfr.washington.edu/FUSION/fusion_overview.html

​

Also free for small datasets is Lastools. The creator, Martin Isenburg has an excellent blog as well.

If you know python or R there are some great packages:

laspy https://laspy.readthedocs.io/en/latest/

lidR https://github.com/Jean-Romain/lidR

​

For educational resources:

I've taken some good courses online with Penn State World Campus. I haven't taken their lidar one, but it looks pretty good.

https://www.e-education.psu.edu/geog481/syllabus

There are lots of resources out there you don't have to pay for, and colleges are always a bit behind the industry. I see more programs popping up these days that teach not just GIS but focus more on remote sensing and geodesy. I would look for something with that kind of focus rather than your standard GIS program. Honestly, you can learn a lot about the work if you try out some mapping using a drone with a camera and then create a point cloud using structure from motion (aka phodar). Software like Pix4D, Agisoft Photoscan have free trials I think.

For lidar textbooks I recommend the one by Shan and Toth:

https://www.amazon.com/Topographic-Laser-Ranging-Scanning-Principles-ebook/dp/B009NZVX2W

Also, it's always a good idea to read up on and understand accuracy standards and file formats at some point:

https://www.asprs.org/a/society/committees/standards/Positional_Accuracy_Standards.pdf

https://www.asprs.org/wp-content/uploads/2010/12/LAS_1_4_r13.pdf

​

For drone based lidar, the company to pay attention to these days is Phoenix LiDAR.

Hopefully gives you some of what you're looking for. Best of luck!

Well, it depends on how hard you are willing to work,

Lazy and just want to kinda get used to terminology:
Learning Radiology by Herring

Willing to put in 2-3 hours every day during the rotation which by the way is entirely feasible since med students definitely aren't doing more than 40 hours a week, most do like 30 during a rads rotation. Use Core Radiology

Difficultish: Brant and helms, the harrisons of radiology. But unlike harrisons where legit everything is covered, if you really want to learn radiology you have to get subspecialty specific textbooks like the requisities series. That said, this is what I used back in the day during med school and I definitely don't regret it. I've read through core radiology as well, they are kinda similar in content, but B&H is a bit more formal and teaches radiologist principles better. If you are going into radiology, this is the textbook to buy since you'll probably use it in residency during PGY-2.

And in general, you are never going to read the entire textbooks during med school, but for IM or EM docs, Core could be super useful even though it will be beyond them for certain topics.

For physics, this is my favorite book by far. It can be a bit dense, and some in my opinion more ignorant radiologists who dislike extensive physics don't like it as much, but I learned during training physics makes the radiologist. Even among radiologists, too many doctors make basic physics mistakes that lead to misdiagnosis, especially with things like nuclear imaging. I frequently overread cardiologist and GI nuc imaging and am kind of appaled by the complete lack of basic radiation understanding. That said...

Here are the amazon links, you can probably find pdfs to some of the books and those that aren't you can probably find in your hospital library.

https://www.amazon.com/Learning-Radiology-Recognizing-Basics-3e/dp/0323328075/ref=sr_1_1?ie=UTF8&qid=1500633396&sr=8-1&keywords=radiology

https://www.amazon.com/Core-Radiology-Approach-Diagnostic-Imaging/dp/1107679680/ref=sr_1_2?ie=UTF8&qid=1500633396&sr=8-2&keywords=radiology

https://www.amazon.com/Fundamentals-Diagnostic-Radiology-Set-Brant/dp/1608319121/ref=sr_1_1?s=books&ie=UTF8&qid=1500633979&sr=1-1&keywords=brant+and+helms

Specifically for MRI:
https://www.amazon.com/Duke-Review-MRI-Principles-Case/dp/1455700843/ref=sr_1_1?s=books&ie=UTF8&qid=1500633869&sr=1-1&keywords=duke+MRI

^Great book for the basics of MRI artifacts and connects visual artifacts to the physics, although learning how to differentiate between artifact and pathology is going to take a residency ;). Also, make sure to get the online version because the paper edition is shit quality.

Yea, so all in all, everyone can find a book that will satisfy their level of interest in radiology, and of course, you get out what you put in. You put in a lot of time in the rotation, that is your decision and I think it was worth it. I learned more of my physics principles during my rotation(although it helped I was an engineer) than residency, so when it came time to take physics CORE, I didn't have to study. Physics CORE is basically the step 1 of radiology, the exam can be hard as shit, and unlike step 1, there is no UFAP or UWORLD lol.

Radiology textbook can be obscure in that they often don't explicitly mention physics principles, so if you don't them, you can't truly appreciate a textbook in my opinion, and how I studied radiology basically was I always had four textbooks open at any given time.

Robbins for pathophysiology, Whatever radiology textbook I was using, a copy of Netters, and maybe an embryology review book if I felt it was necessary. Never steered me wrong, radiology and anatomy textbooks open at all times are especially important, but try to keep the anatomy book and pathophys book closed while "interpreting" the textbook, only to re-correlated after you have thought about it and read a section to get a second more in depth look.

Costantly reminding yourself of principles is important and often missed. I am sure all of you know radiology is one of the most basic science heavy specialties, so reviewing your basic sciences, even well beyond medical school, makes for a fantastic radiologist.

However be careful not to get attached to any given textbook as well, you can't exactly have netters and robbins with you in the reading room.

Congrats on your promotion! I did my undergrad in Geography and am almost done with my MPH, so fellow GIS person here. There is an interest group in the American Association of Geographers you can reach out to if you haven't already. I'm not sure what your baseline is for public health, but I've included two books I've liked and used for reference on occasion. I'm sure you'll know all the geography concepts, but it's nice to see how they relate to the public health side.

I know a lot of universities offer free classes for their employees, maybe you could take a couple of public health courses if you were so inclined just to get a good baseline. I'm not sure what area of public health your doing your work in, but it's never a bad idea to pay attention to publications to see what's new.

Congrats on joining neuro! I think I know where you work (what can I say, there aren't a lot of neurologist using that type of magnet in Canada), but reddit is anonymous so I'll leave it at that.

So I actually use an outpatient imaging facility called Animal Scan. They have human trained MR techs run the magnet. After working with both vet techs trained by their docs and human MR trained techs, I can tell you that the training that they have makes a huge difference. My MR tech can do things with that magnet that I didn't know where possible. So the real answer is, to be really really good, you probably would have to do all of that course work (which I think takes 1 to 2 years)

That being said you are in a very common situation. Hopefully as the new neuro tech certification gets off the ground we can work on a specific CE for you guys.

I haven't read it, but I hear good things about this book: http://www.amazon.com/Rad-Techs-Guide-MRI-Instrumentation/dp/0632045051/ref=sr_1_1?ie=UTF8&qid=1373753133&sr=8-1&keywords=mri+tech

And I have a question for you: how do you like that magnet? Ever had a critter (like a big dog T spine) that wouldn't fit in it? How long does it take you to scan a large dog TL? There are lots off rumors about that magnet, but I have yet to talk to someone who actually runs one.

If you use 3/4 Nyquist it is indeed correct that it won't be monotonic - this is the weakness of single points on the curve of a function trying to convey all of the necessary information. On the other hand, if you're curious what's going on at very fine scales - the place to look /is/ what's going on near Nyquist. Even if there are nonidealities. And you can design a metric that glosses those over, for example integrating between (say) 3/4 and Nyquist, which would be much better conditioned. The wider the bandwidth the better conditioned it is, until you just end up at SQF.

If you want to capture "sharpness," it really is optimal to just use SQF. Perceptual sharpness was simply figured out a long time ago. Hultgren's modified SQF is superior to the original, in my opinion.

The more complicated behavior I can't help you with (perhaps look in my two reference books on this topic...)

Composites of smear and jitter are easy to model (even multiple smears) - just convolve several jitters or smears together with the .conv syntax. If you want to learn prysm, I would recommend keeping an eye on the v0.17 release notes. This release is due in the next little while (a few weeks, probably) and will break a lot of way the library was used in <= v0.16 to reduce the amount of vocabulary you need to know to use the library.

The program itself (I learned on the 2013 version) comes with three guides, as I recall. The tour guide is the only one that comes to mind at the moment. Maybe the field guide is another. I used the tour guide primarily. The annoying thing was learning the program with the guides that were not updated. So if a lesson says it should take x amount of time, it will take more, due to you having to figure out where certain tools have been moved to.

Here is the 2010 tour guide, its probably the one I used.

I would also suggest taking the time to learn about the chip & subset tool, and supervised and unsupervised classification. Those are the most powerful tools I learned to use. I really like remote sensing, and would love to land a job doing at least some rs. Its a great way to create your own raster data.

If you are looking for reading on the topic of RS, I used two books by John R. Jensen, Remote Sensing of the Environment, and Introductory Digital Image Processing. The latter being the most useful imo.

Definitely Bolstad. QGIS is free and great software. If you’re wanting to get some experience with ArcMap, Esri’s GIS Tutorial books are great. Only $30 to buy and you get a code for an advanced license with full extensions for 6 months.

My lab had this book by Ashby. I didn't use it that much but the first few chapters do a good job of introducing concepts behind proper experimental design and why design is so important to the GLMs you'll use to analyze the data. To be honest though, Vince Calhoun is the real person to listen to when it comes to fMRI analysis. He has a way deeper and broad understanding of the bold signal and how to analyze it than old school people like Friston or Ashby.

I haven't seen evidence to say that GIS is necessary to get a job, but I still strongly recommend it. I know several people, myself included, who have been told that GIS experience has gotten their resumes taken out of the pile.

Even if your school doesn't offer a course on arcGIS, the company that puts out the software offers a pretty good workbook that comes with a trail of the software if you want to look at it yourself.

If you have the time and money or library access, this book Color Appearance Models - M Fairchild, is pretty good and comprehensive. Colour is a bit of a rabbit-hole topic, it goes quite a long way down (for instance different camera manufacturers have different color models and as I understand sell modified versions in different geographies -so point a Canon and a Nikon at an X-rite and you get different results)

Also this guy's blog is pretty good http://www.strollswithmydog.com/perfect-color-filter-array/

The ease of coding it should be independent of the number of values you are working with if you are using a software capable of matrix multiplication like MATLAB. I've coded it manually in R, largely because I find the pre-written packages poorly notated—it's not too difficult.

> What book could I refer for just the basic introduction to Kriging?

This is a good introduction, I've found. It seems to come from this book.

The pic is from this book called "Microcosmos". (note: this is a link to Amazon)

It's pretty great, there are a lot of cool pictures in it. I like to keep it around my desk to flip through while I wait for things to load on my computer.

I found [Gauge/Gravity Duality] (https://www.amazon.co.uk/Gauge-Gravity-Duality-Foundations-Applications/dp/1107010349) by Ammon and Erdmenger to be very well written and a pleasure to learn from, I don't know if that constitutes beautiful.

I had a hard time with this too. the book that eventually ended up giving the best explanation (for me) was this one: http://www.amazon.com/MRI-Ray-Hashman-Hashemi-PhD/dp/1608311155/ref=sr_1_1?ie=UTF8&qid=1407170208&sr=8-1&keywords=mri+the+basics

It was available online for free at my institution.

Remote sensing and image interpretation is a good read and a great addition to an office bookshelf. Dated in that some better stuff isn't there but a lot of it still holds relevant today

http://www.amazon.com/Remote-Sensing-Interpretation-Thomas-Lillesand/dp/0470052457

You could probably find a better price or another source googling around

It is a very interesting study and one of the latest books virtually proved it is genuine. Will give you details later

by Giuliani Fanti, but also Bernard Ruffin and Ian Wilson. Also by one of best believing historians (Warren H. Carroll)

I'm nearing the end of my geography major. As someone who is just starting (and struggling big-time) to learn the programmatic side of things, you really have a leg up on the competition. The programming language of choice for GIS apps is Python, so if you still want to be doing some programming that is the language you want to focus on. A Geography grad avgs 50k/year. A geog major who knows python averages 75K!

Broadly speaking, I'd recommend picking up a book like ESRI's Getting to Know ArcGIS and working the examples there. http://www.amazon.com/gp/product/1589483081?keywords=arcgis&qid=1450722894&ref_=sr_1_2&s=books&sr=1-2

Get to know key terms like rasters, vectors, shapefiles, and the basic operations like clip, buffer, etc. And above all realize that everything exists in space and time, so everything can be analyzed spatially!

Wow, thanks!

http://www.amazon.com/Advances-Imaging-Electron-Physics-135/dp/0120147777/ref=sr_1_1?s=books&ie=UTF8&qid=1348254629&sr=1-1

You might appreciate this book on remote sensing (used of course, also check eBay) I came across in grad school (spatial analysis & processing satellite imagery) that's more along the lines of algorithmic processing in post production rather than composition in the field. It's a great look (academically speaking) at the language of math as it applies to handling rasters.

[Ninja edits: jfc autocorrect...]

The "point" I am making is that people in this thread are going around saying Violet is this and Purple is that... but...

Who got to decide that?

Because it certainly isn't the court of public opinion, who couldn't give a shit about wavelengths or spectral purity or eye response.

How do you know the claim made by the OP is even true?

Looking around the net, most websites that discuss the matter seem to be just copying each other as if it was an urban legend. Many dictionaries give multiple definitions (as opposed to the "strict" single definition given by the OP), and wikipedia just cites a book that is targeted towards industrial uses (as opposed to colloquial use).

>Magenta, then.

My point exactly.

If it wasn't for the common industrial use of magenta in printers during the last few decades, nobody would give a fuck about magenta being a combination of two wavelengths. Everyone would still be thinking of that color as just a color. Like yellow. Or purple. Or violet.

Just because an industry or scientific field creates a definition of a word for their own use, doesn't magically make it also the definition for colloquial use, e.g. your average redditor.

I took the registry a few months ago and while I don't want to discourage you I feel it's best to be brutally honest. I took the test after taking classes and clinical for my bachelors degree. I also want to state for the record that I passed my rad boards with a 94 and my CT boards with a 89... That being said the MRI registry was the hardest test I've ever taken. I passed with a 77... And I was shocked when it came out that high.

Part of the problem is I couldn't find any good study materials. The one registry review book on amazon is really sketchy... Lots of wrong answers, some outdated material... And I found it didn't reflect the boards at all. Being away from it so long is going to make it even harder for you.

If you really want to do it though, go all in. Try and find some CE seminars through the ASRT or other organizations, that would probably be your best bet. Or see if the ASRT has those learning modules for MR like they do for CT.

Edit- included link for my review book. But read the reviews, they are on the money.

Not this again.

The scientific studies purporting to "prove" the shroud's origin are just awful. Behind the vast majority are Giulio Fanti, whose recent career has involved studying nothing but the shroud, which he's clearly convinced is real before performing the experiments (this is not good science). His main results are rejected by the scientific community--the tests used to establish an origin around 0 AD were not published in a scientific journal, but in a book Fanti wrote (because they were not considered reputable) (1). The tests he used (including IR, Raman, and a mechanical test) did not follow established protocols; they were calibrated in Fanti's lab, verified by no other party, and immediately used to date the shroud. The archbishop of Turin has claimed "there is no value to these experiments" (2). Some of the results Fanti actually managed to get published (the so called "biological evidence") have been retracted as "data presented in this article are not sufficient to support the conclusions drawn". (3)

You can question the carbon dating if you like--but there is not any real evidence supporting the shroud's origin ~0 AD. Given that the shroud was entirely unknown until the 14th century, a much earlier origin is unlikely.

These are all in a great coffee table book called Microcosmos that I can't recommend enough. That copy is a large paperback version that I haven't seen, though. I have the smaller hardbound version but apparently it's 70 bucks on Amazon now, wtf.

ETA: I've never had a guest over that didn't eventually pick it up and spend 20-30 minutes flipping through it. It's fascinating.

Maybe work through a full book on the subject? Like this: https://www.amazon.com/Gauge-Gravity-Duality-Foundations-Applications/dp/1107010349

USDA, FBI, CIA, USACE, USNAVY, USARMY, USAIRFFORCE, USNPS, USF&W, HHS, USFS, NASA (for rocket launches) and multiple state governement agencies too, from my experience working with these data and professionals directly: TDEC, TWRA, TVA.

This is in no way an exhaustive list, and I can provide context for each of these groups. Mostly this is just from Jensen's Remote Sensing of the physical environment 2nd, which, even though is from 2006 and there is new data for these topics now, does a wonderful job of describing topics for those without STEM backgrounds.

The source of this image is Microcosmos: Discovering The World Through Microscopic Images From 20 X to Over 22 Million X Magnification by Brandon Boll (Amazon link). The Daily Mail wrote a review including several other images from the book a couple of months ago.

Seconded. Another book in that vein is Ashby's Statistical Analysis of fMRI Data:(http://www.amazon.com/dp/0262015048/ref=rdr_ext_sb_pi_sims_2)
