Enroll in my ZBrush Online Course!

Ever wanted to learn how to use zbrush for didactic 2D illustration?

Missed our Zed for Your Head Workshop at the AMI Meeting last year?

Don’t know anything about zbrush2018 or how awesome its new tools are for cleaning up segemented dicom data?

Just like zbrush and want to learn more?

Join my Online zbrush course now!

I created a series of videos for the workshop I co-taught at the 2018 AMI Meeting and I have made them available to you as part of an online course on Teachable. Join me as I show you some of my tips, tricks, and tools of the trade using zbrush for 2D medical illustration.

Included in the class are topics such as manipulating shadows and the environment, using wax preview for a realistic bone affect that mimics subsurface scattering, and how to render B&W line art directly out of zbrush.

As a bonus, I show you how to use some of the new tools in zbrush2018 that I have found especially useful for medical illustration. I use a fun character sculpt for my primary example but I’ll show you a ludicrously simple, fast, and effective way to cleanup segmented dicom models.

This is an intermediate course. Check out a free preview here.

What is Clinical Anaplastology?

Clinical anaplastology is the area of medicine that deals the with prosthetic restoration or rehabilitation of a malformed or absent area of the face or body. Unlike prosthetists, anaplastologists don’t make limb prosthetics, though they do create prosthetic fingers, toes, feet, hands, breast prostheses (called somato prostheses). Anaplastologsits create several types of facial prosthetics including auricular (ear), nasal (nose), ocular (eyeball), orbital (the eyelids, sockets, and surrounding area), and midfacial (the nose and significant tissue extending from it which may include the cheek or orbit). It’s an important area of work that can have life-changing effects for patients, improving function, appearance, and overall wellbeing.

To create a life-like facial or somato prosthesis, the area must be sculpted to visually match and physically fit the patient’s existing anatomy. The finished sculpture is then molded and cast in silicone. It is custom colored to match the patient’s skin. Anaplastologisists aim to capture even the tiniest details including blood vessels, hair, and freckles. Additional anatomy such as eyes and nails can be made from other materials.

Digitally sculpting a sphenoid bone in zBrush

The sphenoid bone is my absolute favorite bone in the human body. So delicate, so beautiful, so important. I made this sphenoid bone by compositing models made from a couple different MRI DICOM datasets (OsiriX) in Zbrush and cross-referencing them with a model of the skull floor we made using photogrammetry (123D Catch).  I then scoured all the atlases I could get my hands on, looking for quality turnaround photos and illustrations of the sphenoid, and sculpted my heart away. (Special shout out to the Rohen and Thieme atlases I love so well!)
