Three-dimensional dosimetric considerations from different point A definitions in cervical cancer low-dose-rate brachytherapy
PURPOSE To investigate the dosimetric difference due to the different point A definitions in cervical cancer low-dose-rate (LDR) intracavitary brachytherapy. MATERIAL AND METHODS Twenty CT-based LDR brachytherapy plans of 11 cervical patients were retrospectively reviewed. Two plans with point As following the modified Manchester system which defines point A being 2 cm superior to the cervica...
متن کاملAssessment of indoor cancer linked to accumulated radiation dose from different types of television sets in dwellings
Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

متن کامل”Maximum dose” points in cervical and endometrial cancer medium dose rate brachytherapy
Background: Best dose distribution in target volume and control of Organ at Risk (OAR) dose are the two main goals in brachytherapy. Materials and Methods: In this study in vivo dosimetry in 4 rectal points was performed by Transillumination Dosimeter (TLD) s and the measured doses were compared in different patients. One point was reported to have the maximum dose in each patient and the very ...
متن کاملUterine perforation and its dosimetric implications in cervical cancer high-dose-rate brachytherapy
PURPOSE To retrospectively assess the incidence of sub-serosal and uterine perforation of intra-uterine tandem in intracavitary high-dose-rate (HDR) brachytherapy for cervical cancer, and to evaluate its dosimetric implications on computed tomography (CT)-based treatment planning. MATERIAL AND METHODS Computed tomography images and brachytherapy plans of cervical cancer patients treated from ...
