An Investigation of the concomitant doses from Cone Beam CT and CT simulation in Radiotherapy,Effective doses were measured on the CT Simulator and CBCT using TLDs and an anthropomorphic phantom. The effective doses obtained for the CTSim for pelvis and abdomen scans were 7 and 9 mSv respectively. Effective doses obtained from the CBCT ranged from 3mSv for a low dose pelvis scan to 24mSv for a standard dose thorax scan.

Monte Carlo Investigation of Stereotactic Radiosurgery of Spinal Metastases,iosurgery (SRS) of spinal metastases. Two treatment plans were generated using the Eclipse Pencil Beam Convolution (PBC) and Analytical Anisotropic Algorithm (AAA) for each of three patients diagnosed with spinal metastases. Retrospective Monte Carlo dose calculations were performed on the same pati

Impact of Kilo-Voltage Cone Beam Computed Tomography on Image-Guided Radiotherapy of Prostate CanceRT) of prostate cancer with Monte Carlo method. In this study, the 10 MV photons from the treatment head and the 125 kV photons from the on-board imager of a Varian Trilogy linear accelerator has been modeled with EGS4 Monte Carlo code. Using multiple source models as beam input, Monte Carlo dose ca

Amongst them the Microbeam Radiation Therapy (MRT) and more recently the Minibeam Radiation Therapy (MBRT) showed promising results. In the MBRT, the beam thickness ranges from 500 to 700 micrometers with a separation between two adjacent minibeams of the same value, whilst in the MR
