Explososcan: a parallel processing technique for high speed ultrasound imaging with linear phased arrays.

摘要: The data acquisition rate in medical ultrasonic imaging devices is limited by the acoustic propagation velocity tissues. Typically such machines image lines are produced sequentially one line per transmitted pulse. A parallel processing scheme has been implemented which enables to increase a factor of four through simultaneous B‐mode from each individual broadened transmit higher can be used frame produce independent images that averaged reduce noise, or conventional at standard video rates while reducing patient exposure. Alternatively, field view increased over normal scan without sacrificing rate. These advantages achieved with little reduction measured resolution. design and performance this device described. sample vivo included.
