A Monte Carlo based inverse treatment planning system (MCI) has been developed which combines arguably the most accurate dose calculation method (Monte Carlo particle transport) with a 'guaranteed' optimization method (simulated annealing). A distribution of photons is specified in the tumour volume; they are transported using an adjoint calculation method to outside the patient surface to buil...

Artificial sources of radiation account for approximately 14% of the annual radiation dose from all sources of radiation. Because of the increased lifetime risk per unit dose for children, radiographic procedures could lead to increase the radiogenic risk of cancer. This study intended to review the pediatric doses in planar radiography procedures and to assess different methods used to reduce ...

Introduction: According to the literature, optical coherence tomography (OCT) can be used measure radiation absorbed dose. This study was carried out to design a computed tomography system for the calculation of absorbed dose and optimization of dose delivery in radiotherapy using gel dosimeters. Material and Methods: An advanced charge-coupled device based OCT system was developed in laborator...
