According to the Occupational Outlook Handbook,
“Medical and scientific illustrators combine drawing skills with knowledge of biology or other sciences. Medical illustrators work digitally or traditionally to create images of human anatomy and surgical procedures as well as three-dimensional models and animations. Scientific illustrators draw animal and plant life, atomic and molecular structures, and geologic and planetary formations. These illustrations are used in medical and scientific publications and in audiovisual presentations for teaching purposes. Illustrators also work for lawyers, producing exhibits for court cases.
Medical illustrators must have both a demonstrated artistic ability and a detailed knowledge of living organisms, surgical and medical procedures, and human and animal anatomy. A bachelor’s degree combining art and premedical courses usually is required. However, most medical illustrators also choose to pursue a master’s degree in medical illustration. This degree is offered in four accredited schools in the United States.”
The annual salary range is $41,933-$79,547.
