[ 1 ] - Activation of Radioadaptive Response via Injected Serum of Irradiated Rats with Low Doses of Ionizing Radiation
Introduction: One of the protective concepts in the interpretation of radiation damage in radiobiology is the radioadaptive response. The objective of this present report is to evaluate the induction of radioadaptive response in male rats by injection of pre-irradiated serum with low doses X-radiation intraperitoneally. Materials and Methods: 80 male adul...
[ 2 ] - Clinical Medical Physicist Training Program at Reza Radiotherapy and Oncology Centre (RROC)
Introduction: It has been shown that there is a strong correlation between training and improving the Radiation Oncology Medical Physicist (ROMP) and an Oncology Department Quality Management plans. The Reza Radiotherapy and Oncology Centre (RROC) beside of its development plan, has recently implemented a comprehensive in-site training plan based on ROMPs abilities and the Depa...
[ 3 ] - Evaluation of a systemic change of Superficial X-ray tube characteristics
Introduction: Very low, Low and Medium X-ray machines are used extensively for Superficial Radiation Therapy mostly used for Basal Cell, Squamous Cell Carcinoma, and Melanoma skin cancers. In most of cases, Superficial X-ray Therapy (SXRT) is preferred to Electron beams generated using a linear accelerator. SXRT tube characteristics may vary with the use of the machine for a lo...
[ 4 ] - Treatment couch positioning uncertainties using an EPID-based method
Introduction: The accuracy of patient positioning plays an important role for radiotherapy tasks. Short and automated Quality Assurance (QA) programs are becoming one of the challenging tasks in Radiotherapy. The current study, investigates the accuracy of treatment couch positioning with four degrees of freedom (4DoF) using a fast and accurate method based on an image acquired...
[ 5 ] - Radiation Oncology Medical Physics Workload calculation: A Change in Current Workload
Introduction: It is an essential activity to quantify the Radiation Oncology Medical Physics (ROMP) workload for a safe, secure and progressive department. Due to the most recent development at Reza radiotherapy and Oncology Centre (RROC), a workload calculator tool is provided. Materials and Methods: The Project was performed in different sections includin...
[ 6 ] - Evaluation of Testis functioning during Pelvic Radiotherin the presence of testis lead shield
Introduction: Rectal and bladder cancer are the most common disease among young man. Although External Radiotherapy (EBRT) is one of the most effective treatment options introduced so far, the testis undesired radiation dose increases the risk of infertility and hormonal malfunctioning. The testicles are usually outside of the radiation field, but they can be exposed either to ...
[ 7 ] - Assessment of a 2D EPID-based Dosimetry Algorithm for Pre-treatment and In-vivo Midplane Dose Verification
Introduction: The use of electronic portal imaging devices (EPIDs) is a method for the dosimetric verification of radiotherapy plans both pretreatment and in-vivo. The aim of this study was to test a 2D EPID-based dosimetry algorithm for dose verification of some plans inside a homogenous and anthropomorphic phantom and in-vivo, as well. Materials and Methods: </strong...
[ 8 ] - Transfer of Radio-Adaptation via Serum: A Preliminary Report
Introduction: Adaptive response is one of the important concepts in radiobiology. The present report aimed to transfer the radio-adaptation via serum. Material and Methods: In total, 50 male adult Wistar rats were randomly divided into 6 groups, including control, serum control, low-dose (100cGy), low-dose/lethal, serum/lethal, and lethal (8G...
