A mammography test object that gives a more natural looking image than a purely geometric phantom, supplementary to TOR MAS or TOR MAX. One half carries filaments, micro-particles and low contrast details, the other simulates breast tissue with micro-calcifications.
A range of tissue equivalent materials supplied in many sizes and shapes, including moulded or machined cavities to house dosimeters. The materials are suitable for both kV and MV energies, so they can be used for diagnostic and radiotherapy dosimetry work.
A routine mammography test object supplied with a 7 cm attenuator stack. It covers sensitometry, resolution limit, low and high contrast detail detectability and simulated micro-calcifications, so a simple score can be recorded at each test session.
