Method of detection of microcalcifications by ultrasound

摘要

Methods and devices for imaging of microcalcification particles using ultrasound. The method may include delivering a multi-pulse transmit packet of an acoustic line to a predetermined location within a tissue having or suspected of having a microcalcification; causing the microcalcification to move or oscillate, comparing one or more received signals from the location over multiple transmissions, and determining frequency modulation of the returning pulses as a result of the microcalcification oscillation or random pattern movement.
