Ultrasonic device, scanning control method of ultrasonic imaging system and related components

Abstract

The invention discloses a scanning control method of an ultrasonic imaging system. The scanning control is applied to the scanning control system of an ultrasonic imaging system based on a 360-degreering array probe, and comprises the following steps: calculating each array element number calculation value used in the scanning when the scanning control is carried out for any time; when one or more array element number calculated values exceeding the preset array element number range exist in each calculated array element number calculated value, replacing the array element number calculated values exceeding the array element number range with the same number of array element numbers of adjacent array elements, so that the number of the array elements used for scanning this time is consistent with the number of the calculated array elements; and after replacement of each array element number calculation value is completed, starting a corresponding channel based on each array element number calculation value. By means of the scheme, the situation that the image effect at the boundary is poor is avoided. The invention further provides an ultrasonic device and a scanning control related assembly of an ultrasonic imaging system, and the scanning control related assembly has corresponding effects.

Description

technical field [0001] The present invention relates to the field of ultrasonic technology, in particular to an ultrasonic device, a scanning control method and related components of an ultrasonic imaging system. Background technique [0002] In the current ultrasound imaging system, the definition of the ultrasound probe will include the first array element and the last array element, that is, the concept of boundaries. When the imaging area covers the entire image area, in the many times of transmissions required for a frame of image, generally the transmission and reception apertures calculated by the previous few transmissions or the last few transmissions will cause some elements to cross the boundary. For example figure 1 TX1 in. [0003] Since the out-of-boundary element does not exist in the physical sense, it will be ignored in the calculation, which will cause the transmit / receive aperture to be lower than the actual aperture, resulting in an image effect near th...

Problems solved by technology

[0004] If it is in the two-dimensional imaging mode, the solution of smoothing + spatial compounding can solve the boundary problem to a certain extent, but in blood flow imaging, elastography, contrast imaging, when the selected ROI (region of interest, interested area) across both sides of the image, the image effect at the boundary will be poor, affecting clinical use and diagnosis
