Abstract


Radiation therapy , surgical treatment and chemotherapy , consisting of three tumor treatment . The fundamental goal of radiation therapy is the maximum concentration of the radiation dose irradiation to the lesion ( target ) to kill tumor cells and surrounding normal tissue and critical organs from unnecessary exposure or as little as possible by . Medical electron accelerators actual parameters physicist in the process of radiation therapy in the treatment plan pre - defined parameters may not match the phenomenon , which will give the patient safety risks , so the treatment process , real-time than on the parameter information is extremely important . In this paper, a medical image archiving and transmission system (PACS) DICOM (Digital Imaging and Communication in Medicine) standard widely used in image display DCIOM on this basis , and patient treatment parameters have been included in the image information . Radiotherapy course parameters likely will occur to change the accelerator control end to install the server-side program , physicist workstation to install the client program , server-side according to the client's requirements , be able to real-time return to treatment parameters , the physical division if found parameters are changed , the treatment must be stopped immediately . Finally, by the high energy of the accelerator itself radioactive sources for imaging to obtain real-time viewport image (Portal Image) continue to adjust the position of the multi- leaf collimator , radiation therapy planning image multiple alignment using registration shape , scaling , making real-time the viewport image radiotherapy planning images as close as possible to improve the precision of radiation therapy .
