Abstract
One of the objections to using a time-sharing computer as a treatment planning aid is that the most commonly used terminal, a teletypewriter, is not very well suited for generating the graphical records a physician relies on to prescribe a course of radiotherapy. In an effort to provide this information, the authors have developed a new system which employs a PDS-1 display terminal manufactured by the Imlac Corporation, Waltham, Mass. Consisting of two parallel processors sharing 8k of 16-bit memory and a 21 inch CRT display, the PDS-1 is linked to the large Dartmouth Time Sharing Computer via a 2000 band voice grade telephone line. Both curves and alpha-numeric data can be drawn, transmitted, received and manipulated while on line with the remote computer. Alternative field arrangements are selected in seconds with a light pen, hard copy is produced in less than a minute by an alpha-graphic printer. The hardware is significantly less expensive than the small dedicated computers now available for treatment planning work, and can be implemented on any time-sharing system.
