CT DATA RECONSTRUCTION

AUDIENCE  Physicians, students
FORMAT  Digital illustration
MEDIA  Osirix / InVesalius / ZBrush / Photoshop

This is a fun little project based on a CT data image set available on OSIRIX's website. OSIRIX is a free open-source viewer that's very useful for working with the DICOM file format that is common to various medical imaging technologies such as MRIs, CTs, PETs and so on. You can generate 2D imagery and 3D models from a patient's dataset, and it's great fun to transform images that would normally only be legible to a radiologist into something that's a little more accessible to everyone.


The process

THE RAW DATA

The MELANIX images from the OSIRIX CT Dataset were assembled in InVesalius and Osirix.
Relevant anatomy layers were carefully extracted into separate base models, including the bones, skin, lungs, musculature, mammary glands, and brain.

THE ZBRUSH TREATMENT

The extracted files were individually imported into 3D sculpting software ZBrush for tidying, remeshing and texturing. Shown here: the skull before and after treatment.

 

Here are the multiple anatomy layers stacked as 3D models in Zbrush. 2D Images of these anatomy layers were individually then exported at sufficiently high resolution into Photoshop to anticipate a possible print use.
