The motivation aspect in developing these kinds of numerically automated machines involves the expensive costs in manufacturing the complex curved geometries in 2D or 3D constraints mechanically. The development of treadmills considers the factors like easier programming in CAM and easy storage of programs. A program might be changed easily and get away from manual errors. Numerically controlled machines are far better to operate, and also the complex geometry comes in a reasonable price.
In the wide medical graphic design area, you might elect to drive your job around the medical illustrator track. In such a case, you should have a graduate degree in Medical Illustration. Its graduate program curriculum is a mixture of illustration and medical science topics. Some in the courses of the program are Surgical Observation & Sketching, Electronic Media, Human Gross Anatomy and Physiology.
