| pubmed-article:1364284 | pubmed:abstractText | The authors discuss the present-day problems of radiotherapy. They show the major prospective trends in this field and describe the OS3Dplan system, made in this country, that represents a working place of a radiologist and serves for the development, analysis and storage of the schemes of long-distance gamma-beam therapy of oncologic patients. The OS3Dplan system is realized via the IBM PC/AT-286/287 computer but can operate with any of the IBM PC/XT/AT/PS-2--8086/80486 computers, made before 1986 with the videoadapter EGA/VGA, and functioning under MS-DOS, Microsoft (version 3.3 or older). The mathematical provision of the videodigitizer (distance control and videocamera) permit the introduction of videoinformation into the personal computer in the 256 x 256 format, 512 x 512 pixels. The mathematical provision of the OS3Dplan proper permits a volume planning of long-distance gamma-beam therapy. This module type system will be of interest for various specialists (radiologists, roentgenologists, oncologists, students, etc.), for it permits a collection and maintenance of a data bank on patients with imaging of roentgenograms, CT, NM tomography, ultrasonic data on the computer display and printing these data, perform metric analyses and reconstruct the volume. | lld:pubmed |
