It is intended to be a flexible platform for multi-modal ultrasound imaging research, mainly oriented to breast diagnosis. Up to now, the following imaging techniques have been implemented:<\/p>\n<p>&#8211; Phased-Array full angle spatial compound (FASC).<br \/>\n&#8211; Acoustic Radiation Force Imaging (ARFI) full angle spatial compound<br \/>\n&#8211; Ultrasound Computed Tomography (USCT) speed of sound and attenuation reconstruction<\/p>\n<p>The system is formed by two 3.5 MHz, 128 elements and 0.22 mm pitch arrays (P2-4\/30EP, Prosonic, Korea) that rotate with 95 mm radius into a water tank, controlled by independent stepper motors with an angular resolution of 0.1\u00ba. A 128 channel full parallel ultrasound system (SITAU-112, Dasel, Spain) is used for excitation and signal acquisition. While only one array can be used as emitter, both of them can act as receivers, allowing pulse-echo and through-transmission operation modes. The system is able to perform emission and reception beamforming in real-time (useful for implementing image compounding algorithms) and also gives access to the individual signals received by each array element (useful for USCT reconstruction). Finally, a standard personal computer controls the motors movement and the ultrasound equipment with Matlab scripts.
