Ultrasound Tomography (UT) has proved effective for soft-tissue (breast, liver, testicles...) characterization; it reduces also the operator-dependency observed in echography. A half-ring transducer array was designed based on the breast anatomy, to obtain reflectivity images of the ductolobular structures using tomographic reconstruction procedures. These(More)
The main goal of ultrasound tomography (UT) is to provide both a high contrast imaging and a multi-parametric imaging. Within the frame of soft-tissue imaging, we focus our application to breast inspection for early stage cancer detection. Conforming with breast anatomy, ANAI¨S (ANAtomical Imaging and Interventional System) prototype is designed(More)
Ultrasound tomography has considerable potential as a means of breast cancer detection because it reduces the operator-dependency observed in echography. A half-ring transducer array was designed based on breast anatomy, to obtain reflectivity images of the ductolobular structures using tomographic reconstruction procedures. The 3-MHz transducer array(More)
Pulse compression methods improve the quality of ultrasonic medical images. In comparison with standard broadband pulse techniques, these methods enhance the contrast-to-noise ratio (CNR) and increase the probing depth without any perceptible loss of spatial resolution. The Golay compression technique is analyzed here in the context of ultrasonic computed(More)
