Quality assurance programmes on three (3) mammography units located in Accra have been carried out using standard performance criteria. Darkroom quality control and a number of quality control tests with respect to: tube voltage accuracy and reproducibility, radiation output linearity and consistency, mean glandular dose (MGD) were assessed for each unit.(More)
The current brachytherapy treatment planning system employs the TG 43 formalism proposed by the American Association of Medical Physicists in Medicine (AAPM). The TG 43 uses dose rate tables which assume cylindrical symmetry of the sources, and the medium in which the calculation is made is water equivalent, with no modification for different(More)
The study is to evaluate the effect of collimator selection on image resolution with varied acquisition parameters. Images were acquired by placing a quadrant-bar phantom on flood field uniformity Phantom filled with a 99m-Tc solution. The method involved varying the Acquisition parameter by using LEAP collimator after which the LEAP is replaced with the(More)
Cancer incidence estimates and dosimetry of 120 patients undergoing hysterosalpingography (HSG) without screening at five rural hospitals and with screening using image intensifier-TV at an urban hospital have been studied. Free in air kerma measurements were taken for patient dosimetry. Using PCXMC version 1.5, organ and effective doses to patients were(More)
