Abstract

The use of a compact, mobile, relatively inexpensive electromechanical patient contouring mechanism is described. The system utilizes a Numonics Model 224 graphics digitizer suspended over the patient. The digital X and Y coordinates of the patient contour in either of multiple, parallel transverse, or sagittal planes are inherently accurate to within 0.25 mm over a total reading area of 6090 cm. Display features include the interface to an analog 11 in.17 in. X–Y plotter with a variable scale down factor for those contours which would otherwise be larger than the plotting surface. The system is easy to use and may also be readily interfaced for on line entry of patient contours to calculator or minicomputer based treatment planning systems.
