Utilize the head and neck phantom, lung phantom and simulated human phantom to detect the spine tracking accuracy of Cyber Knife during IGRT, and give evaluation. Use CT to scan the head and neck phantom, lung phantom and simulated human phantom which have films set in, then make use of the treatment planning system to design plans for tracking cervical vertebra, thoracic vertebra, lumbar vertebra,...
To improve the coverage of irradiation on tumor and resolve the problem of dose shortage at the edge of tumor beside sensitive organs, we will discuss about designing divisional target plans for massive liver cancer. On the stage of designing treatment plans, we divide the Planning Target Volume (PTV) into three sub-targets: PTV1, PTV2 and PTV3. PTV1 and PTV3 are the regions for designing treatment...
With spine auxiliary positioning during IGRT treatment, utilize the simulated human phantom and dynamic lung phantom to detect the accuracy of fiducial tracking, and evaluate the value of it. Utilize CT to scan the phantoms which contain films, and design plans for phantoms and spine auxiliary positioning which use 1, 2, 3, 4, 5 and 6 fiducials for tracking, respectively. Each phantom plan shall be...
