| Abstract [eng] |
National Cancer Institute seeks to improve the performance of brachytherapy (a procedure used to treat certain types of cancer). They presented a problem - how to track the location of the radiation source in real-time and model the accumulation of emitted radiation. The model was successfully created, capable of locating the location of the radiation source as well as creating a visualization of the accumulated radiation. A program prototype was created to realize the created model. Though program prototype only accepts complete data input, it and the model are suitable for real-time localization and radiation accumulation solving. Radiation source localization tested with with multiple approaches. All approaches localized with big error, however, however error was directly dependant on precision of radial and anisotropy functions. Solved simplified path optimisation, finding the optimal path, irradiating all planned space in minimal time. A dynamic programming algorithm was used for this. |
