A computer-assisted, interactive radiology learning program.
A computer-assisted adjunct to traditional radiology teaching files is described. The student is presented with an image and questions with multiple choice answers. The student's choice leads to additional presentations that reinforce correct responses and provide a critique of incorrect answers. The process is under the control of a teaching script. Requirements for the system included the ability to present high-resolution radiology images along with text; high capacity for storing teaching scripts and images; ease of use by students and authors of teaching scripts; and reasonable cost. A prototype program was written in C-language and run on an IBM PS/2 (IBM Corp., Armonk, NY) with DOS. The hardware also included a 30 megabyte disk drive, an IBM Image Adapter/A and a 14 inch IBM 8514 monitor operating at a 1024 X 768 X 8 bit resolution. Image acquisition was accomplished with a high resolution Pulnix video camera (Pulnix Corp., Tokyo, Japan), with an Imaging Technology (Imaging Technology Corp., Weston, MA) frame grabber, attached to an IBM PC/AT. All hardware is available commercially. A sample teaching file was constructed using a case of ischemic colon after a cecal volvulus. Students used the system and provided a critique. Results indicate that computer-assisted teaching programs can be a valuable addition to traditional teaching methods in radiology.
