ULTRASONIC WAVE METHOD AND APPARATUS FOR MULTI-LINE ACQUISITION

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic wave method and apparatus for acquiring the multi-line acquisition type ultrasonic wave data. SOLUTION: The ultrasonic wave signals are transmitted to the region of interest and the echo signals are acquired and analyzed to generate the first data stream (276) related to the first received beam. At least two successive data samples are passed being removed from the first data stream by the decimation of the first data stream to form the data stream (286) finished with the first decimation. The use of the pattern of the decimation achieves the band width a half or three-quarters in the data sampling rate after the decimation. COPYRIGHT: (C)2005,JPO&NCIPI
