DICOM Anonymization and NII Creation with dcm2nii
Переглядів 6 тис.7 років тому
This short video describes how to use the dcm2nii program to anonymize DICOM images and convert them to NII format. The NII format is a "cleaner" format that makes it easier to store and distribute imaging studies.

Materialise Mimics and 3Matic Tutorial
Переглядів 35 тис.8 років тому
This video walks through the process of taking a CT lumbar spine myelogram and turning it into a 3D model that fits together with dowels. Materialise software (Mimics and 3Matic) is used.
Site is down and no data
Tnx, that was great♥️
Brilliant, hope you do more videos again
good efforts for explaining mimics software. thank you
🤞🏻the files are still there .
I found it ! ( 6 years ago give or take I saw this video and have been looking for it ever since ) so grateful for these videos and knowledge thank for your time . Is slicer and meshmixer free for Mac. It’s not slicer for fusion 360 right ( i think that’s discontinued anyways and meshmixer isn’t fusion I’m sure .. just really new . I’m god at photoshop this seems like another level. Anyone recommend where to go to start off learning this program and why u think this might be a better program vs others . Thanks
Very good
Thank you for the tutorial doc. I wanna ask is there any library or package or method where i can do autosegmentation for 1000 tibial CT Scan?
Maybe, but I'm not directly aware of one. Explore slicer plugins and "automated tibial segmentation"
Post processing of ct ear: ua-cam.com/video/4XjLJ7vhpk4/v-deo.html
Thank you so much for the tutorial. Gonna try it after later in my final year project. ^_^
Can anyone tell me where can I get the Dicom CT scan images ?
why when i click draw then click erase, nothing happens, i want to erase using draw tool
Loved this thank you.
Can you please upload the CT scans for practice?
please give the sample data in description.
how i open nii file
I'd recommend 3D Slicer. Free, works on all platforms.
Hey Justin, thanks for the tutorial. I found in really helpful. Can you kindly provide me with some sample CT scans to begin practicing with?
Are there other software for skull stripping other than ITK ? specially for CTA? Thanks
Generally skull stripping of CT is best done by thresholding. E.g. set all voxels > 500 HU = min value. It's a nice part of working with CT - skull stripping is much easier!
Should have trace all the inner str , & facial nv ..
Very useful! Thanks a lot!!!
Great thank you.
Any one has this software ?? Thx
thank you so much! If you have any fracture cases you could do walkthroughs for that would be incredible as well. thanks again!
Thank you Justin, Do you know any online free library to download anonymous MRI scans for Pelvis area to train on them ?! .. I have been searching for a week now with no results
thank you for the video, it helped me alot, but i'm curious why does it generalize two nifti files? in my case i gave the software a chest CT scan folder and it returned 6 compressed nii files ? how do i know which one am i supposed to use?
Often it's doing some sort of correction such as for gantry tilt in the extra file. Typically it will add a prefix like "o_" to the corrected file. Check out the dcm2nii documentation to figure out what exactly it's doing. Or...you just have multiple series in a folder of DICOM files and it's creating an nii for each of them. View the nii files to find out - you can, for example, view them in 3D Slicer
@@justincramer9557 bless your soul ♡ u helped me alot 😊 thank you
Assalamu Alaikum Great lecture sir Short but very much precised.I m 1st yr radiology resident in Bangladesh.Definitely this will help me a lot. Sir At 12.36 is it Canalicular or labyrinthine segment?
Damn...good catch! Yes, that's the labyrinthine segment.
Is this with or without contrast?
I believe this one is without. Usually if someone orders a CT temporal bone with contrast, I look to switch to something else. Head, soft tissue neck, CTA, etc.
When you create a new mask there are two tools "Keep largest" and "Fill holes" - what can they do with the object? Can this negatively affect the mask?
Hello. i am novice of Dicom. i want to process anonymization quickly with pyspark. how can i do that??
I've never used pyspark. I did tweet (@justincramer) my own python code for DICOM anonymization at github.com/radiplab/dicom_utils - comes with no guarantees whatsoever but may provide some guidance.
Perfect. Thanks
Hi. May I know, do you purposely left out the cancellous bone inside vertebral body?
No - for my current models I manually fill in those areas. It all gets filled in with support material anyway so it's not a big deal, but it's easier to work with solid structures in CAD.
@@justincramer9557 can you do tutorial for that too? Your videos very helpful for my study.
@@shurah100 I don't have a Materialise license anymore, but it would be straightforward. Play around with tightening up your threshold, using hole fill, then manually fill in any remaining gaps.
Where did you get this gui tool?
They're now recommending using the newest version, MRIcroGL: www.nitrc.org/projects/mricrogl - run mricron.exe, then go to Import --> Convert DICOM to NIfTI. The GUI tool looks a little different but is still pretty straightforward.
Awesome review, thanks for laying everything out so simply. I’ll be referring to this often :)
Thanks sir
the interactive link isn't working.. it keeps on loading
I was just able to load neurorad.link/cttbone - this currently points to radmodules.com/dwv/walkthrough-ct-temporal-bone.php - if you have a slow internet connection, just give it a little more time. Otherwise I'd suggest trying a different browser. Could be some mishandled javascript error preventing it from loading.
@@justincramer9557 This page could not be found.Any one else?Thanks
Excellent video - very helpful. Thanks.
Super! Keep up the good videos please
Very useful thank you
hi, i'm using the inspector tool but instead of filling in the part, i delete it
Hard to know exactly what the problem is. I will say I hardly ever use hole fill in Meshmixer because it can be difficult. I prefer to just fill in holes while I'm segmenting in Slicer.
Dear Justin, Greetings! I am a Sr. Project Scientist at Indian Institute of Technology Delhi, India. I have recently started working on Mimics. However, I am facing problem regarding the unavailability of tools like Analyze, Edit, etc. on my menu bar. I am trying to get them for the last two days but I failed. Therefore, I am seeking for your help. Can you please guide me by letting me know how to get these tools on my menubar? I am using Mimics21. Regards, Ajay
Ajay - I would reach out to Materialise support, which was quite good the last time I used it. This video is getting a little old, and I would imagine the software looks a little different now.
@@justincramer9557 thank you for your reply. I will now contact the software team. Regards
Justin, hello I´m a radiology resident in Mexico I would really like to translate this. I hope we can get in contact to see if you could do this collaboration.
Sure we can look into that. Can I e-mail you at macox7@gmail.com?
@@justincramer9557 yeah for sure
Very smooth and simple ! Thank you
amazing..thanks
Great presentation! Great tip! Much appreciated! 👍
Thank you so much
Can You Please Make A Video On Design Inside of Heart. Valve and Septum
Hi Justin, once again you have been very helpful. I used your videos before but the cardiac segmentation one is spot on. Keep up with your good work. Massimo
Amazing presentation Justin. Can this be used to Coaxial images of arteries ( Raw output of CTA) to MPT ( longitutional view) of arteries. Let me know
Thanks! Not exactly sure what you're asking. Slicer brings up any image in axial, sagittal, and coronal orthogonal views. MPRs are possible via the Reformat module. Curved planar reformats are also possible but I've not done that.
Awesome video. Very informative and direct to the point. Thanks. I hope you could share more videos like that. Thanks, Justin Cramer.
Amazing presentation. Is there a way to use it for vascualr reconstructions?
Well you can segment the vessels like anything else (best if you have a CTA or MRA), but to my knowledge there isn't a specific Slicer module for vascular segmentation.
