I have volumetric data of medical images where multiple 2D images are stacked together to create a 3D volume. However, I need to annotate features in this volume that are very difficult to annotate by simply going through all individual 2D images. I have yet to also come across an annotation tool where I can have a cutting plane to see into the 3D volume and then do the annotation. So, I have been searching for a tool or a method that can help me annotate features in this image. I have come across tools like CVAT, but I can't seem to annotate it from a 3D perspective.

welcome. this is not a programming question. it is also asking for recommendations. -- you may have to make such a tool yourself. annotating volumes seems tricky. you'd need a volumetric viewer with three orthogonal views to properly position a primitive (cube, sphere, ...) and freeform shapes would have to be based on "brushes" (sphere brush, ...) that you apply on various slices. you might also want a "convex hull" or "spheroid" approximation so you just have to mark near the edges of a feature. – Christoph Rackwitz Mar 08 '23 at 10:31
