They’re freely available on the printables page linked in the video description actually! But I do accept tips if you truly enjoy the model. :)

Thanks so much!

Umm it’s hard to remember for sure, but I’d estimate somewhere in the 2-4hr range. That was outside of the initial time to learn the different software packages

You can get the CD from your doctor and then just need to find a CD reader to upload it to your computer.

@@IZLabs any cd reader? That’s great! So have the 3D slicer to access it ready and with the cd reader, I should be good to go? I thought I’d need access to RadiAnt or a medical processing software. I just have a laptop but I’ll look for a cd reader on Amazon or something.

That’s awesome! Yeah I tried to find the least painful way of doing this haha

It’s likely the scan resolution. You can see if there are other files in your scan package as sometimes they do lower res scans first to locate and then high res. Good luck!

Thank you! I appreciate it!

Have you been able to do it? Have the same case.

Yeah there are a couple comments on ideas for handling this below, but I haven’t heard anyone become successful yet. Good luck!

Theoretically yes! A CT scan would be better suited to picking out the bone, but it’s possible.

Haha I was going for a clean print and a nice visual. All in the eye of the beholder…😂

Haha it’s definitely possible! Usually done with a CT scan instead of an MRI though as it can better pick up the bone. You’d follow pretty similar steps

@@IZLabs but how would you separate the bones on the CT scan?

Similar process, you use the segmentation tools in 3DSlicer to select by density for the bone and then you can manually select the region of interest. There are also some plugins which can automate the process

Oh no! Usually happens if the selection isn't completed. Did you make sure the 2D images had sections highlighted in green?

This may be tough without a contrast agent being used. But if there was contrast used with your scan you may be able to see it. I'd probably look at an anatomy reference and then look at the layers in 2D to get close. Then you can convert just a small section to 3D and carve away to find what you're looking for.

That would be cool to see for sure! Glad you enjoyed the video!

Hey, this is a pretty common question. I’ve provided some links to potential workarounds in the other comments, but long story short you might just be out of luck as none of them have reported back with success

Glad you liked it!

Hi Marius, thanks for taking an interest in the project! Unfortunately the app is no longer available worldwide via the App Store as I had to pay a yearly $100 fee to keep it active and I couldn't justify the cost anymore. You can still find the code on my GitHub here if you want to run it locally on your phone though! Hope that helps: github.com/IZ-Labs/RingRewards

I would bet the records are still around! They make a point of keeping them. You will need DICOM to make this process work easily I’m afraid. I’m not sure of the process at your hospital, but it shouldn’t be too crazy an ask for them to supply the files if you call the patient services number and ask for patient records request

Haha I was wondering where all these people were coming from! Thanks for the referral and glad it was useful for you. I took a look and your brain came out well lol!

So we meet again

That’s awesome! I hope it works out for you!

Haha mission accomplished then! Glad you like them

Have you clicked "Show 3D Model"? If so and it still isn't showing, do you notice any error messages?

@@Me-kt3gh Hi Me. I did click "Show 3D model". What's strange is I started completely fresh today and ran through it and it worked! I'm not sure what is different this time but I was missing something the first time. Before I noticed the brain wasn't glowing green(mask) like in this vid and when I tried selecting stuff things got weird. Thanks again for the help :)

Glad you found it helpful! That may happen if you don’t have a large enough selection in your masking step. Are you seeing green areas highlighted on each of the 2D views? -edit, just saw the previous comments too haha. Yep I think the lack of green highlighting was the issue!

You could theoretically power it using a laptop with USBC power delivery output ports. Just depends on your laptop. I use this with a 60W type C brick that I plug into the wall. But I like the idea!

Haha clearly all hospitals are not alike then. Cause they certainly didn’t do that as smoothly for me or some others I’ve talked to. Glad it was easy for you though!

Yeah I’d be willing to! Why don’t you send an email to my business account (business@iainz.me) and tell me what you’re thinking. I have limited colors (couple different blues, a red, black, white, and the charcoal grey you see in the video), but we can talk details there!

Thanks for the feedback! I'm not sure if this would work on the S key fob. Theoretically it should be the same technology. If you can get me measurements of the model S pcb (I'm assuming you have one), I can check for you!

@@IZLabs Yes! I get 58.6mm long x 26.2mm wide at the center. From the center of the frunk button to the center of the trunk button it's 35.5mm. Any other measurements you need?

I have a model s fob I can send you if your interested

Glad you enjoyed it! I thought about making a card, but it was the thickness that threw me off. It wouldn't fit in my wallet sadly. If you have a thicker wallet, you could probably drop the PCB itself into a compartment and get the effect you're looking for. Thanks!

The slot for the power switch is: 14.5x8.4mm.

@@IZLabsthanks and what switch did you use?

@@wexx1k I used these: www.amazon.com/gp/product/B07JNNXC9N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

@@IZLabsthank you very much! I buy the parts!

Haha it’s definitely a bit of a pain to get used to! Hopefully this video helped, but let me know if there are questions!

​@@IZLabs I appreciate that. This thing is not visually intuitive at all. After loading the DICOM data, then you have to figure out which tracks to "load" to generate the model from. I've got 13 MRI tracks and 6 PET & CT scans and figuring out which is optimal for the 3D model generation is the first stump bump. I'm using what seems to have a decent resolution, though I'm shocked at just how low they are (298x298, rather thought they'd be considerably higher res than that) and which track has the most frames. I'm learning what the shorthand abbreviations mean such as Sagital, but trying to figure out whether Pre or Post is better...a lot of guess work. A couple have in the neighborhood of 200, so I'm going with one of those. Then, the next steps that are just a lot of poking around to see what produces anything, IDK, figure out how to get the 3D model to show up reliably, and that's before I get into the skull stripper plug-in...not visually intuitive software

@@michaellaforte6964 It definitely takes some getting used to... but hey at least it's free haha. For reference, the scan I used to make my model is 240x240 with 158 layers (the count column). The smoothing steps later on will help you visually fix the lack of resolution in some areas. Hope that helps!

@@IZLabs free is key! LOL! Thanks man, that does help!

Hi there! Glad you've enjoyed the tutorial! I had similar issues isolating the cerebellum haha. The thresholding + smoothing approach struggles a bit here for sure. Couple things you can try: first, you can create multiple segmentations and segment masks through the segment editor and have one which better matches the cerebellum structures. Then you just have to combine them in your model. Secondly, you could use the manual painting tool in the segment editor to manually pick which regions you want to keep. This would be a little time consuming, but since it's only part of the brain it's doable. Lastly, I would play with your smoothing settings. If I remember correctly, the smoothing is what really took away the detail from my scan. Truth be told, a combination of all three methods (or at least the last 2) may be your best option. Hope that helps! Let me know when you get it figured out!

Glad you like them haha!

Thank you Ryan! I appreciate it 😁

Thank you!! And great point with the thumbscrew….it definitely already came loose haha

Awesome! Thanks for the kind words!

It’s certainly not perfect, but for an experiment it gets you close. Let me know how it works out for you! Thanks for watching

Hi there, you can reach out via email at: business@iainz.me. Full disclosure, I'm not a medical professional and can't provide medical advice, but I'm happy to see if I can help or point you in the right direction.

Glad you liked it! This seems to be an issue many people face. They don’t always do a 3D high resolution scan. I mentioned a potential fix in one of the other recent comments, but not sure if anyone has tested it yet. Sorry I can’t be more help!

Thanks! I’m glad you liked it!

All a matter of perspective I suppose😂

Glad you liked it!! I appreciate the compliment

I appreciate it!

Thank you!!

Glad you liked it! And haha of course

Glad you found it helpful! It's less about the 'size' and more about the inter-layer spacing. I don't see a place for 'count', but looking in the Volumes window, under Volume Information, the model I used has an image spacing of between 0.95-1mm, i.e. a new scan layer taken ~1mm apart. On some of my less 'high-res' scans, the spacing can go as high as 6mm. My image dimensions are only 240x240 in the version I used. It seems many people are having issues with the lack of layer resolution in their scans. Maybe check out the process I linked below which supposedly allows for interpolation and smoothing over the higher layer separation, though I haven't used it personally. Good luck! Let me know how things work out for you. discourse.slicer.org/t/i-cannot-remove-ridges-in-3d-segmentation/4792/4

@@IZLabs Wow I really can't express how grateful I am for this reply, thank you! I will try out it out and share back here. Btw, I see the 'count' column when I go to the 'Add DICOM data' section. Looking at volume information, here are the stats. Image Dimensions: 512x512x176 Image Spacing: 0.466mm x 0.466m x 1mm So that's odd, it seems my resolution may be matching yours yet I still get a smoothed out model at the end, missing the folds. It also seems that the 'count' column from the dicom section is the same as the last dimension under image dimensions.

I now see the count you’re talking about. I may be misunderstanding you (my apologies if so), but if the actual images look ok to you in the three planes but only lose detail during the smoothing step, that may be the issue? Make sure the smoothing size you are using isn’t too high. And of course, always happy to help 😁; also shameless plug, if it’s been useful, please consider subscribing as it helps the channel!

​@@IZLabsjust liked and subscribed!:) I tried reducing the smoothing but that didn't help. Could you share the image dimensions and spacing dimensions for your high res model? I saw it on the volume tab. Just want to get a sense of how similar they are.

@bit_mic171 I appreciate the sub! That's a shame the smoothing didn't help. If it's still struggling, perhaps try following the steps using the included MRIHead sample data that comes with 3D slicer. That's what I used to make the tutorial video (to not share my brain with the world haha), so I know it should work. If that doesn't work, then perhaps it's the version of Slicer you're using? I've been on 4.11.2 just because I never got around to updating. My parameters for the actual scan of myself that I used are as follows: Image Dimensions: 240 x 240 x 158 Image Spacing: 0.95 x 0.95 x 1.00

Glad you liked most of it. I agree that the voids do add extra complexity, but there was a reason for the madness haha. If you check out my other video on it you can see, but basically the voids were for me to add lights and other electronic components inside the brain. Splitting in 3 parts was done cause I didn’t want to have to use support material and needed a large flat surface to get good bed adhesion. Thanks for your input though!

@@IZLabs Thanks for answering :D I used before FreeSurfer that automatically extract the brain in high quality (same example model as you did). Also 3D printed it. The problem I have is something called anisotropic voxel resolution images that are only high quality in one direction, split by multiple scans. Which no software can correctly extract so far. Very annoying.

Ahhh yeah I’ve seen that issue crop up for a lot of people, very frustrating indeed. One method I’ve seen (but never used personally) is described in this blog post. Maybe worth a shot? Let me know if that works! (discourse.slicer.org/t/i-cannot-remove-ridges-in-3d-segmentation/4792/4)

When I use the software on the mri disc I have It shows all planes in high res. I’m So confused as to how to get them to show as high res on all 3 planes in 3D slicer

Hi there, sorry you're having trouble! It sounds like you had a series of scans done, but may not be viewing the high res 3D scan in 3D scanner. Usually they will do a high res sequence in each plane to try to localize before doing a single full res scan. On the left hand side of the 3D slicer tab do you see the list of multiple scans (under the DICOM, loaded data pane)? Try clicking through a couple different scans, and see if you see one labeled 3D or something similar. When I had mine done, I have about 25 different scans which I can view, and only 2-3 were the full resolution in all three planes. Let me know if that doesn't help and I can try and dig a little deeper for you.

Thanks for the reply! I did check on the left were it says loaded data. I’m on 3D slicer 5.2.2 so it looks a little different but I check all 11 images and they all only have 1 plane as high res. Each of them will have a different plane that is high res which makes me wonder if I can combine them somehow to get all 3 planes to be high res. Also I’ve had 3 head mri and I’m trying the data on all 3. The 11 images is just for 1 of the 3. Thanks for the help btw. I’d really like to get this to work. Such a cool thing print and have!

Ok that would have been the easy fix, but it sounds like you’ve encountered an issue many have where they don’t do a full 3 plane high res scan. It’s quite difficult to align the three scans to form one 3D image due to small movements between scans. One technique is shown in the link below (though I haven’t personally tried it) which may work. But I hope maybe one of your other two scans does contain a combined high res scan as that’s definitely the easiest! Do let me know how it turns out and if I can be of any more help! (discourse.slicer.org/t/i-cannot-remove-ridges-in-3d-segmentation/4792/4)

That post is interesting. I’ll give it a try and hopefully it doesn’t change dimensions since I’d prefer it to be as accurate possible. Either way I’ll reply with my results and thank you for all your help!

Thank you! I’m glad you found it useful😁

Glad you enjoyed it! As for the error you're running into... It sounds almost like the make solid step is somehow eliminating your geometry as a whole. Is the part you're processing really thin or otherwise weirdly shaped? Are you using the default settings on the make solid tool? If that's the only step causing issues, you can skip it and things may still work. Let me know, I'm happy to dive in a bit deeper to help if needed.

Also check the object browser (View -> Show Objects Browser) on Mac, as the make solid step creates a new body, which may be hidden for you.

I ran into this issue too. I was able to solve it by loading the model in Windows 3D Builder. When you import the model, there should be a dialogue box in the bottom right corner that will ask if you want to repair the model. For some reason, this repair method worked for me. After repairing the model, save and import back into meshmixer. You should be able to make the model solid now.

Thanks for sharing!

Thanks! Glad you enjoyed it :)
