RAW DATA-BASED ULTRASONIC PHASED ARRAY DETECTION SYSTEM AND METHOD

摘要

A raw data-based ultrasonic phased array detection system and method. Upon the receipt of an ultrasonic echo signal from a measured object, the ultrasonic echo signal is directly subjected to analog-to-digital conversion processing and beam synthesis processing to generate raw data information; imaging processing is directly performed on the basis of the raw data information; and the raw data information is directly saved as source data for subsequent analysis and calculation. According to the ultrasonic phased array monitoring system and method, down-sampling processing is not performed during processing the ultrasonic echo signal from the measured object, but the raw ultrasound echo signal data is directly retained and subjected to imaging and storage operations, such that the resolution and clarity of an image obtained by ultrasound imaging can be increased to the largest extent, thereby improving the accuracy of ultrasound phased array detection.
