Purpose: In this work, the authors describe an electron sealed water calorimeter (ESWcal) designed to directly measure absorbed dose to water in clinical electron beams and its use to derive electron beam quality conversion factors for two ionization chamber types.
Methods: A functioning calorimeter prototype was constructed in-house and used to obtain reproducible measurements in clinical accelerator-based 6, 9, 12, 16, and 20 MeV electron beams. Corrections for the radiation field perturbation due to the presence of the glass calorimeter vessel were calculated using Monte Carlo (MC) simulations.
Purpose: To determine the current equipment, technology, and treatment planning methods used in Canadian cancer centers for intrauterine cervix brachytherapy.
Methods And Materials: A questionnaire was developed to survey medical physicists in Canada regarding technical aspects of intrauterine cervix brachytherapy. A response was obtained from one physicist at each radiotherapy facility in Canada.
