title: Personal computer based teletherapy CT-RT treatment planning system (TSG-RADPLAN).
abstract: A radiotherapy treatment planning system has been installed on a personal computer and was developed to meet the clinical demands and budgetary constraints of any radiotherapy department. The system consists of an IBM compatible PC-AT computer with a 16 bit microprocessor, 40 MB hard disk drive, and a 5-1/4'' floppy disk drive. The computer is supplied with an analog to digital conversion card for communication with a back lit digitizer. The CT-Interface computer with 16 color extended graphics display unit allows for the transfer of data on contours of the patient body, tumor, critical normal structures, and a density matrix (Housfield numbers) from the CT-Images taken from a CT-Scanner. The system supports software for teletherapy, brachytherapy, combined therapy (tele + brachy) and cancer registry. MS-DOS Version 3.21 is used as the operating system. The programs are written in BASIC, C, and Assembly languages. The system has high performance with speed and accuracy during dose calculations. A dot-matrix printer/plotter is used to print the final dose distribution results in text or graphics for permanent records.
