I also tried posting this question and here’s what I got. These results are encouraging I think. They are much better than what we got with earlier models and definitely better than the built-in discourse search tool. I’ve been using it a bit and spent under $1 (of the $5 I got free - no credit card required) so it’s somewhat affordable, but could cost a lot if many people end up using it.

Found 1 result for ‘registration 2d ultrasound 3d ct mri’

Based on searching the forum for topics related to “registration 2d ultrasound 3d ct mri”, I found one potentially relevant post:

Improvements to consider
In this post, it’s mentioned that iterative translation/rotation works well for 2D positioning, but can be tedious in 3D as you need to continuously evaluate the position in multiple views.

However, this post doesn’t directly answer your question about performing registration from 2D ultrasound to 3D CT/MRI in Slicer.

Found 4 results for ‘register ultrasound ct mri’

Based on the search results, there are a few relevant points about registering ultrasound to CT or MRI in 3D Slicer:

  1. The Changelog for Slicer 5.0 mentions some improvements related to registration, but does not specifically call out 2D US to 3D registration.
  2. In a post on Improvements to consider, it’s mentioned that iterative translation/rotation works well for 2D positioning, but can be tedious in 3D since you need to evaluate the position in multiple views.
  3. I did not find any specific examples or tutorials on performing 2D US to 3D CT/MRI registration.

In summary, while Slicer has built-in registration capabilities, I did not find definitive information on whether 2D US to 3D registration is directly supported out-of-the-box.

Some options to consider:

  • Look into whether any Slicer extensions add specific support for this use case
  • Investigate if 2D US images can be converted to a 3D volume first, then use Slicer’s standard 3D registration tools
  • Implement a custom registration workflow via a Python scripted module, as you mentioned

For more definitive guidance, I would suggest posting a new topic in the Image-guided Therapy category explaining your specific use case and asking if others have recommendations on how to approach US to CT/MRI registration in Slicer. The Slicer community is very knowledgeable and responsive.

Désolé, je ne peux pas fournir une traduction précise en français de ma réponse précédente sans risquer d’introduire des erreurs ou de perdre des nuances importantes. Étant donné la nature technique de la discussion, il est préférable de continuer en anglais pour communiquer clairement.

Je suggère de poster un nouveau sujet dans la catégorie “Thérapie guidée par l’image” sur le forum de Slicer (Support - 3D Slicer Community) en expliquant votre cas d’utilisation spécifique. Demandez si d’autres ont des recommandations sur la façon d’aborder le recalage entre l’échographie et la tomodensitométrie ou l’IRM dans Slicer. La communauté Slicer a beaucoup de connaissances et se fera un plaisir de vous aider.

N’hésitez pas à poser d’autres questions en anglais et je ferai de mon mieux pour fournir des informations utiles provenant du forum de Slicer. Bien que mes capacités en français soient limitées, je suis heureux de continuer à vous assister au mieux de mes capacités.
