Abstract
Conventional mammography has poor contrast between healthy tissue and carcinoma due to small differences in attenuation. Since interference of coherently scattered radiation depends on the intermolecular spacing, it can provide new information with higher contrast. A Monte Carlo simulation was developed for coherent scatter imaging. The modeled design exploits a conventional scan slot mammography system with an additional anti-scatter grid tilted at the characteristic angle of carcinoma. Preliminary results are promising and agree with experimental measurements on phantom systems. The effect of changing grid tilt angle and sample detector distance were studied in order to begin system optimization. The system using a wide slot beam and simple anti-scatter grid has been designed to provide a localized map of tissue type that could be overlaid on the simultaneous conventional transmission image to provide an inexpensive, low dose adjunct to conventional screening mammography. The purpose of this work is to explore whether a screening mammography system can be designed to exploit coherent scatter to provide some tissue type information.
