| Summary: | Заглавие с экрана X-Ray tomography is one of widespread methods of medical diagnostics. Due to its opportunity to visualize inside structure of scanned object it allows to diagnose, for example, cancer cells. Modern medical tomographic setups have lots of advantages such as high resolution, which allows to visualize objects of very small size, high level of reproducibility, which allows to verify obtained results, simplicity of utilization etc. There is certain amount of improvements still can be applied. One of most significant challenges is reducing of radiation dose. Diagnostics of complex structures sometimes requires more time of measurements. That means that dose will increase with time. This work proposes optimized filtered backprojection algorithm as solution for the problem of radiation dose level. |
