The study of the calculating dose possibility on SVST in case of tumor localization in the abdomen and pelvis
In the present study are determined the relationship between the Hounsfield numbers and relative electron density for standard mode scanning computer tomography and computed tomography mode in a conical beam (SVST) areas of the pelvis and lungs. Dose is calculated at SVST for plans for small and large size of the phantom. Deviation is determined of the calculated dose at SVST from the reference and the measured dose. This study examines an example of the dose calculation on SVST for patients with localized tumor in the abdomen and pelvis.
