The illustrated man: Canadian Medicine's interview with a medical illustrator
Med students learn and retain better when their lessons are accompanied by visual aids like medical illustrations.
But to help the doctors of tomorrow, medical drawings need to be accurate and clear. Creating them is a science. Just ask medical illustrator .
"As an illustrator you have to research, sketch and figure out the spatial relationships to say, illustrate a nerve pathway," says Ms Kryski, a Master's candidate at U of T's biomedical communications program -- the only program of its kind in Canada. "Then you have to arrange that knowledge visually so the viewer can easily understand."
She spoke to NRM about what it takes to create an illustration (like the one of emphysema tissue destruction she did above) and the future of 3D modelling applications in medical education.
You first studied fine arts, but what's involved in becoming a medical illustrator?
At first I was very interested in becoming a doctor, but with illustration I found I could join two of the things that excite me.
In our program at U of T we join med students in the first 10 weeks of their training for four hours of cadaver dissection and four hours of lecture every day; covering anatomy, pathology, and neuroanatomy.
As an artist I knew I'd be referring back to the dissections throughout my life, so I took a lot of mental images since I remember things through spatial relations and visualization.
How do you prepare a drawing?
It's a lot of reading and sketching. You need to learn the details and which ones to emphasize over others to make the message clear. There are a lot of things that would be too messy if you just took a picture of them.
To illustrate, say, a nerve pathway, especially in the skull, it's very important to grasp the theory of where things are. Then you arrange that knowledge visually in a way that the viewer will understand, and run it by experts.
A lot of the most complex topics are best captured in pen and ink. Many people learn better from simpler diagrams.
Right now you're working on a experimental U of T web application, --a 3D anatomy tutorial. What's that about?
I've created the pterygopalatine fossa module (to be released) and I'm working on a study evaluating the educational effectiveness of the 3D model on recall compared to learning from static images.
Are 3D programs effective?
I haven't evaluated the data yet, but it looks positive. 75 students participated in the study. They wrote a pre-test on their knowledge of the skull section, half used the 3D module and half used static images as a refresher. Then we conducted a post-test to see the difference in their recall.
Are there other interesting web applications out there along similar lines?
The is neat. It's an online database of CT scans. They started with one cadaver and are trying to build up a library of people. It's important to have a large library of specimens: men, women, children, the elderly... because there are lots of quirks in the anatomy of different groups.
Is there a piece you're particularly proud of?
My was a challenge. I've never seen one like the one I did. There are lots of outer ear and auditory canal illustrations. But to capture the relationship between the inner ear and the brain stem I had to gather lots of spatial information about the two.
Some have the misconception that medical illustrations are just artists playing around with computers. Good illustration is about getting the accuracy of the object. It's a science.
