The changing role of the medical illustrator?

The author takes issue with the claim that the role of the medical illustrator is changing today. Not so, he says. The role is the same, and the need is as great as it ever was. Rather, some medical illustrators are changing in the desire to expand their field and become "biocommunicators.' Such expansion, the author suggests, is not for everyone, and those who choose to continue in their traditional role need make no apologies. It is a vital one.
