Aims: Chest X ray is the first choice for investigation of cardiovascular and respiratory disease. Radiographer technologists are responsible managing radiation exposure to patients providing adequate image quality according ALARA (As Low as Radiation Achievable) concept. The knowledge skills radiographers in performing chest radiography helps improve diagnosis diseases. aim this study was asse...
Background: This study aimed to estimate and compare the absorbed dose, lifetime cancer risk and mortalities due to cone-beam computed tomography (CBCT) and panoramic examinations on patients. Materials and Methods: The exposure factors were applied to 332 patients in two age groups (6-10, and ˃18-year-old). The dose-area product (DAP) values were measured for CBCT and panoramic radiographies. ...
