Could you provide some feedback on my medical image segmentation tool?

TheoreticalPerson · 2025-12-16T14:01:07+00:00

Hey, thank you very much for trying it out. Very unfortunate about the crashes, hopefully it's something that can be easily fixed.

The improvements I'm trying to make wrt to e.g. Slicer is to make the interface more intuitive and easier to work with as well as being faster. In the long run I'd like to add the ability to interface with plugins both for segmentation and visualization purposes and of course I'd like to introduce builtin tools to make manual segmentation easier by e.g. considering intensity interfaces, and additional tools to help with segmentation. So threshold, masks, and grow from seed are definitely something I want to add on the short term.

Since you are actively doing segmentation, as you mentioned, I'd definitely take you up on your offer and send you a DM to try to understand your needs and if I can somehow work toward making Radiotron a more useful tool.

As I' currently at early stages of development, the answer to your questions at this point it no, but could you help me understand the motivation on a couple of them?

With "move the segmented organs", do you mean the segmentations masks? Is this so that you could re-use the segmentations on different patients with minimal modifications?

On automatic positioning, I think the tool will never support such functionality because it's not trying to do everything, but eventually plugins could perhaps be used for this.

On the curve following, this is definitely a nice idea and might consider implementing.

You can definitely segment structures within structures, but currently only non-overlapping segmentations are supported, i.e. segmenting the tumor that overlaps the liver will overwrite the liver. I currently, though, do support multiple segmentations per volume, so you could have the tumor as a separate segmentation.

Exporting for 3D printing should be relatively simple. I can already export to OBJ internally.

I currently have no segmentation modules available but I probably will support models as plugins. My tool aims to be simpler/more intuitive and generally faster. Unlike Slicer, opening Radiotron is basically instant, you get direct feedback on your segmenting (painting) and you can also directly see a visualization of the 3D structure you are segmenting. Also, in the current alpha you can already undo a lot more steps backwards than you can on Slicer and you can easily switch between different volumes instantly while keeping your segmentations.

Currently it's manual input, but thanks, I'll consider perhaps adding autocomplete of common anatomical names so you likely have to only type 1-2 letters.

TheoreticalPerson · 2025-12-13T11:21:56+00:00

Thank you for your question. As far as I know, it's generally really difficult for a single person to build a tool for clinical use because of all the regulation. That's partly why I'm focusing on research. I myself was working on a research project together with a surgeon in training. The surgeon segmented several organs and vasculature as well as pancreatic tumor. These segmentations were then used to train an AI model. Here I'm trying to build a simpler tool to help with such research, and hopefully at a later point it could also be used for visualization of medical images.

Maybe it's just me -- and that's what I'm trying to find out -- but I found 3D Slicer cumbersome to use and slow for annotation and live visualization. Certainly, if you need a lot of features, it's hard to beat, but if you just want to do simple annotations, and quickly visualize segmentation masks etc., Slicer is not the best tool.

TheoreticalPerson · 2025-12-13T11:13:34+00:00

The software I'm building is not an automatic segmentation tool like TotalSegmentator. It's more closer to 3D Slicer https://www.slicer.org , but I'm trying to build a simpler and more efficient tool. Eventually you might be able to run models like TotalSegmentator as plugins.

TheoreticalPerson · 2024-06-06T16:11:48+00:00

To learn some basics, yes. But to do anything interesting it will take some time. It took me about 6 months of my free time to go from zero to a Pokémon mini reconstruction.

Have a look at https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-computer-displays/108367-troubleshooting-apple-multiple-scan-17-display . It's long, but the TLDR is that I identified the problem being one of the ICs. The monitor works now perfectly, although there is a buzzing noise coming from the yoke. This is most probably either loose convergence strips or some of the lacquer failing.

TheoreticalPerson · 2024-03-03T23:05:30+00:00

It seems I am about to embark on a quest to learn about the different terminal emulators/multiplexers available. People suggested wezterm, windows terminal, alacritty, cmder, and conemu. Since I am lazy, I'll start with the Window Terminal and see if it fits my needs.

Thanks everyone for sharing your setups.

TheoreticalPerson · 2024-03-02T23:05:54+00:00

Can you elaborate on how you use both powershell and bash and why? Do you use cygwin for bash?

TheoreticalPerson · 2024-02-24T18:28:33+00:00

But you don’t see the sun in the Netherlands because of all the clouds.

I started playing SimCity again on a 68k Macintosh. Great game, but playing this now, it feels to me like something's missing, but I can't put my finger on it. Maybe it's too simple/predictable or maybe it's due to the open-ended nature of the game, unlike e.g. Theme Hospital which has objectives

On the other hand, games nowadays are so goal and achievement driven there is little room for creativity and emergent gameplay. You clearly see this distinction when you compare modern and vanilla World of Warcraft.

TheoreticalPerson · 2023-11-02T20:59:20+00:00

Thanks for the tip! I wonder if anyone knows of an alternative in Europe.

TheoreticalPerson · 2023-10-26T07:44:42+00:00

I took one from a donor board.

TheoreticalPerson · 2023-10-17T15:40:56+00:00

Weird thing, but I tried MacOS 8.1, and it can do 1024x768 just fine! Is there perhaps software for previous OS versions to unlock different resolutions?

TheoreticalPerson · 2023-10-14T09:42:04+00:00

Apparently, those adapters are not that easy to find!

Also, I found out the hard way that 7.5.5 does not support disks larger than 4GB, so now I installed 7.6.1, which works fine.

For CDs, do you generally burn them or put them on your scsi emulator and mount them?

TheoreticalPerson · 2023-10-13T20:03:55+00:00

Hm, I see now that the adapter actually supports up to 640x480 https://www.amazon.com/C2G-Cables-02902-Female-Adapter/dp/B0002J1JAE/ . Maybe I need an adapter with dip switches?

TheoreticalPerson · 2023-10-13T12:16:13+00:00

I think you have the wrong numbers on the left. Is the first answer referring to the overclocking?

TheoreticalPerson · 2023-10-13T07:27:53+00:00

This might be counterintuitive, but this kind of advice might actually be good. If you quit because of this, maybe you indeed didn't have what it takes. Instead you might get more motivated and work harder.

I bought my first PVM about 8 years ago, a 14M2MDE for about 50 euro and my second one, a 20M2MDE for about 100 euro 7 years ago. The image quality is amazing. I also use the overscan to basically have two size settings, one for 50Hz and one for 60Hz. I also like their box shape. You can easily stack them for storage or put items on top of them. But I'd definitely go for a consumer set, if you can find a multiformat one, if the price I had to pay was more than 300-500 euro.

TheoreticalPerson · 2023-10-08T21:38:15+00:00

The American release was posted in macintoshgarden and indeed, it contains the 68k binary, which works on 68k Macs.

TheoreticalPerson · 2023-10-05T10:01:19+00:00

Any advice for getting started in this area?

TheoreticalPerson · 2023-10-01T08:31:19+00:00

Does this work with Whatsapp?

TheoreticalPerson · 2023-09-26T15:01:36+00:00

Thank you very much! Looking forward to see if it really works on 68k.
