| Abstract [eng] |
Radiation therapy is used for about two-thirds of all cancer treatments, is a technically complex method that requires continuous improvement of medical device parameters, which more accurately form and direct rays toward damaged tissues. Radiation therapy is planned for each individual so that the tumor is irradiated with a sufficient dose of radiation and evenly on all sides, and healthy adjacent tissues and organs receive the lowest possible dose and remain intact. The whole radiological planning group is involved in compiling the radiotherapy plan: oncologist, radiotherapist, radiologist, medical physicist, clinical radiobiologists. The challenge for the medical team is to determine several optimal positions of the irradiation isocenters in an irregularly shaped large volume tumor. Isocenters can be determined by several methods using different computational techniques. This research paper provides a sequence of steps for the detection of multiple isocenters in any irregularly shaped large volume tumor using the Blender software. Methods discovered in the course of the work: how to determine the center line in any body of irregular or regular shape, and the determination of optimal irradiation isocenters, which will damage the smallest number of healthy cells. |
