ANAIS: An ultrasound mammograph

It is well established that ultrasonography is a 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, based on a 1024 semi‐circular motorized antenna, provides more efficient way to view anatomical ductal structures of the breast. Quantitative volume parameter cartography is the unique means to make objective, reproducible, and operator‐independent diagnoses (Computer Aided Diagnosis). The recovery of quantitative acoustical parameters requires solving a nonlinear inverse scattering problem from large amount of measurements. This is achieved using advanced computing resources; a front‐end acquisition system based on 32*1024 multiplexed channels and specific reconstruction procedures. The objective is not only to offer a multiparameter tissue characterization using reflection and transmission measurements but...
