A comparison of computer generated visualizations
of temporal bone (Os temporale) with traditional
medical illustrations for medical education
Overview
Medical education entails learning assisted
by images, illustrations and other forms of
traditional drawings. These illustrations are
used to teach a complex surgical or radiological
procedure, to define typical or atypical patterns
of spread of disease or to illustrate normal or
aberrant anatomy. Even though the hand-drawn
illustrations convey meticulous information,
computer generated images and visualizations
start to play the leading role in medical
education. In this project, specific
anatomical features of the temporal bone were
generated by illustrative visualization
techniques. The pros and cons of these
computer-generated images as compared to
traditional medical illustrations in terms of
time, quality, efficiency, clarity and use were
analyzed. These illustrations were used to
develop a comparatively less expensive teaching
module /reference guide for medical education,
training as well as for providing information to
patients. Unsegmented CT scan datasets of
temporal bone were used to generate the images.
