US technology images blood flow to breast, kidney tissue
By AuntMinnie.com staff writers
California start-up Sensant of San Leandro unveiled clinical images of micro-vessel blood flow inside breast and kidney tissue at this year’s RSNA show. The images were generated with Sensant’s new ultrasound probe technology, Silicon Ultrasound, which uses silicon-based transducers rather than conventional piezoelectric, crystal-based probes, along with the SonoVue ultrasound contrast agent from Esaote of Genoa, Italy. Silicon Ultrasound technology is based on work performed at Stanford University on capacitive microfabricated ultrasonic transducers (cMUTs).
