A computer program for planimetric analysis of digitized images

Planimetrical measurements are made to calculate the area of an entity. By digitizing the entity the planimetrical measurements may be done by computer. This computer program was developed in conjunction with a research project involving measurement of the pneumatized cell system of the temporal bones as seen on X-rays. By placing the X-rays on a digitizer tablet and tracing the outline of the cell system, the area was calculated by the program. The calculated data and traced images could be stored and printed. The program is written in BASIC; necessary hardware is an IBM-compatible personal computer, a digitizer tablet and a printer.
