Focus correction for ultrasound imaging through mammography compression plate |
摘要 |
A coherent imaging system includes a transmitter and a receive beamformer which are programmed with transmit and receive time delays, respectively, that take into account time-of-flight errors caused by an intervening mammography compression plate between the biological tissue being imaged and a phased array of ultrasonic transducer elements. A simple ray-tracing method is utilized to adjust the transmit and receive time delays according to compression plate thickness and speed of ultrasound propagation to mitigate spherical aberration due to the compression plate.
