2D silicon strip sensors using particle physics readout technology have been evaluated as mammographic detectors. Two different versions of the APV series of front-end electronics were used that provided different noise levels. The sensors were evaluated using a typical mammography X-ray spectrum. The spatial resolution was evaluated using line pair test patterns and the modulation transfer function (MTF) was measured using the Edge Response Function. Low contrast performance was measured using the TOR(MAX) test object. Limiting spatial resolution of 52 mum was obtained and an MTF value of 0.1 at 16 1p/mm. The low contrast performance was estimated from 250, 500 pm and 6 min diameter objects and was found to be 11.5%, 7% and better than 3.8%, respectively. (C) 2002 Elsevier Science B.V.
