Interactive atlas of joint anatomy on MR images.

We designed and developed an atlas of joint anatomy based on MR images. Using a workstation that consisted of a computer and a videodisc player, each with its own monitor, the program presented complete sets of labeled MR images of the joints by using a variety of common pulse sequences in standard imaging planes. The images were stored on videodisc and were retrieved and displayed under the control of the computer program. The images could be viewed in a self-paced, structured sequence or in any arbitrary, self-directed way. Interactive features included a quiz mode that challenged the user to name the anatomic structures, one at a time. The atlas has been exhibited at national meetings and currently is used in our residency and fellowship training programs.
