Embodiment Construction

[0015] like figure 1 As shown, it is a schematic diagram of the general sequence principle of four scanning lines, that is, color Doppler scanning is performed in a normal sequential manner, and batch data processing is performed on the obtained echo data, wherein the interval between each scanning line is 1 / prf. Existing scan sequences such as figure 2 As shown in A, that is, according to the scanning line numbers {#0, #1, #2, #3}, the space interval between two adjacent scanning lines is d.

[0016] like figure 2 As shown in B, this embodiment adopts the optimized sequence to select the spatial location:

[0017] When the number of scanning lines is 4, after the first root #0 is determined, the distance between it and the selection is Within the spatial range, that is, any one of the spatial distances d, 2d, and 3d is scanned as the next line, and the sum of the spatial distances of all scanning lines in a batch is 8d.

[0018] Then adopt the updated scanning order, ...

Abstract

A digital ultrasonic frequency doubling and sequencing method. By setting the array elements to receive and sequence the echo signals in an optimized order, the spatial interval corresponding to the two adjacent scan lines in the time sequence is larger, thereby avoiding subsequent beamforming. signal interference during the process. The present invention can avoid echoes of other transmitted signals as much as possible, thereby reducing interference and greatly improving image quality.

Description

technical field [0001] The invention relates to a technology in the field of medical equipment control, in particular to an ultrasonic random color Doppler optimization scanning method. Background technique [0002] Existing ultrasonic color Doppler imaging continuously emits multiple times at a fixed pulse repetition frequency (prf) interval, and obtains the tissue movement velocity by calculating the phase shift of the echo signal. The echo signal is collected at the receiving delay corresponding to the transmitted signal, and the information of one scanning line is obtained through beamforming. Because it takes time for the tissue to absorb the echo of the ultrasound, the minimum value of the receiving delay is the period of the pulse repetition frequency, that is, 1 / prf. In actual detection, when the receiving delay setting is close to the lower limit, it is easy to happen that the receiving array element receives the echo signals of the last several transmissions at a ...
