Abstract

The invention relates to the technical field of phased array ultrasonic scanning, and discloses an ultrasonic scanning method based on spaced phased array elements. The method comprises the followingsteps: selecting discontinuous adjacent array elements in a phased array as an effective array element array, and taking other array elements except the effective array element array as an invalid array element array; controlling the effective array element array to be turned on, and controlling the invalid array element array to be turned off; calculating the emission delay time of each effectivearray element according to the position relationship of the effective array elements in the effective array element array in combination with the emission focusing parameters; controlling the effective array element array to perform ultrasonic delay transmission according to the transmission delay time; calculating the receiving delay time of each effective array element according to the positionrelationship of the effective array elements in the effective array element array in combination with the receiving focusing parameters; and controlling the effective array element array to perform ultrasonic echo delay receiving according to the receiving delay time. The method has the technical effects that the focusing effect is not limited by the number of channels, and the quality of scannedimages is high.

Description

technical field [0001] The invention relates to the technical field of phased array ultrasonic scanning, in particular to an ultrasonic scanning method, device, system and computer storage medium based on spaced phased array elements. Background technique [0002] At present, ultrasonic diagnostic technology has become the preferred technology in medical image diagnosis, and plays an extremely important role in clinical diagnosis. In ultrasonic diagnostic technology, the scanning technology and beamforming technology of the ultrasonic front end are the key technologies of ultrasonic imaging. [0003] Phased array transducers consist of an array of small piezoelectric elements that can be individually controlled and receive feedback signals independently. Through the combination and collocation of different delay rules, the deflection and focusing of the sound beam of the phased array can be realized, such as figure 1 , figure 2 shown. In the same way, flexibly controlli...
