ANAIS : Ultrasound mammograph

Résumé

It is well established that ultrasonography is an cost-effective, patient-friendly imaging modality available for breast imaging. The main aim of this paper is concerned with a tomographic ultrasound mammograph allowing 3D-reconstruction of the uncompressed breast immersed in a water tank. The scanner provides more efficient way to view anatomical ductal structures of the breast. Quantitative volume parameter recovery is the unique means to make objective, reproducible and operator-independent diagnoses (Computer Aided Diagnosis). The recovery of quantitative acoustical parameters requires solving a non-linear inverse scattering problem from large amount of measurements. This will be achieved using advanced computing resources ; front-end acquisition system for 1024 channels - a channel records the signal acquired by one piezo-composite element, and specific reconstruction procedures. Depending on the possibilities, five to fifteen minutes will be required to perform the full 3D acquisition.
