Document Summary
Challenges in mammography study of soft tissues. Equipment components: generator, x-ray tube - t/f combinations, focal spot size, detectors, aec system, grid, compression devices, visualization system. Safety issues: radiation protection, electromechanical risks, ergonomics. Other mammo techniques tomosynthesis equipment, cedm. Needs to be a lower dose, less quality needed. A lump or clinical sign has been felt. Tomosynthesis, magnification and cedm are generally for diagnostic in australia. Tomosynthesis is used for screening in some places. Above is diagnostic, the right breast has increased density. This is a male, it is smaller, and the pectoral muscle is more vertical (in females it is. It is a lesion that is near the skin so a lump would have been felt more oblique) Mainly fat tissue, less or almost no glandular tissue. There is a microcalcification cluster on the left side closer to the chest wall. This is magnification, there is malignancies and they need to be detected.
