RESUMEN

In this paper, a three-dimensional precise conformal radiotherapy treatment planning system based on a cobalt-60 teletherapy unit is introduced. With the help of additional precise target localization and conformal field-shaping devices, the TPS can greatly improve the performance of conventional cobalt-60 teletherapy units in precise target localization, radiotherapy planning and dose delivery. The clinical practices show that the TPS has advantages of reliable precision and an affordable price , and it is urgently needed in our country.

RESUMEN

We put forward an image rendering system based on pipeline framework for processing and displaying medical images. Compared to original computer graphics algorithms divided into volume rendering and surface rendering, this framework can effectively comprehend methods of computer graphics and image processing, import some new concepts such as vertex buffer, pixel buffer and texture buffer. We implement Shaded Surface Display, Maximum Intensity Projection, Digitally Reconstructed Radiography, Multi planar Reformation, Curved Planar Reformation and Interactive Virtual Endoscopy in our new developed PACS image system.
