Radiologic Anatomy: An Interactive System for First Year Medical Students Richard Rathe, MD Linda Lanier, MD Jon Seymour University of Florida Gainesville, Florida

INTRODUCTION Radiologic Anatomy, an interactive videodisc system, was developed at the University of Florida, College of Medicine. It is targeted to freshman medical students who are required to take credit course work in Radiology during their first semester. The course is designed to teach students anatomic recognition in all imaging planes and in most imaging modalities and serves as a foundation for subsequent Radiologic Pathology and Clinical Radiology courses. Radiologic Anatomy is taught concurrently with the Gross Anatomy course which allows a high degree of reinforcement of key anatomic relationships. In the past the Radiologic Anatomy course had been taught using film packets containing hundreds of images in various modalities specifically compiled and labeled for the course. Presenting the material in this manner proved to be time consuming for both faculty and students. In addition, the cost of reproducing the packets restricted the number of copies available to the students for study. The Radiologic Anatomy program has been developed for use at computer/videodisc workstations which can be placed in the laboratories, study halls, or library thus increasing accessibility of these materials to the students. The design is flexible and allows the program to be a supplement to other course work or be utilized as a free standing, self-study course. IMPLEMENTATION The system was designed around a standard CAV videodisc containing a complete set of radiologic and anatomic images. Radiographs were captured directly using a Panasonic TQ-3031 videodisc recorder and a Sony DXC-3000 broadcast quality camera. The software was written using Claris HyperCard with added support for polygonal buttons. Student workstations consist of a Pioneer 4200 videodisc player with a 19 inch monitor attached to an Apple Macintosh computer.

DESCRIPTION The Radiologic Anatomy courseware is organized into several HyperCard stacks that relate to the various areas of study: * Abdomen * Chest * Head and Neck * Lower Extremity * Upper Extremity * Anatomic Correlation * Clinical Correlation * Radiologic Technique

The system is fundamentally a twodimensional browser allowing the student to study several structures on a single radiograph or a single structure on multiple radiographs. Structures are categorized by topic areas, for example, "Clavicle" falls under the "Chest Wall" category in the "Chest" stack. (Figure 1) The student has the option of limiting the current session to a single category or reviewing all relevant structures and categories for each image. (Figure 2) At any point the student may call up correlative materials related to radiologic technique, gross anatomy or abnormal radiology. A self evaluation mode allows the student to gauge his or her progress at any time. The software selects a structure and displays an unlabeled radiograph. The student must then identify the structure by clicking on it with the mouse or typing its name. Immediate feedback is provided for both right and wrong answers. After the desired number of structures have been attempted the system evaluates the student's performance. The student has the option to review any structure by clicking on its name in the right or wrong answer lists. (Figure 3)
