Problems solved by technology

During the debugging and use of the ultrasound system, there may be bugs in the ultrasound scanning image, specifically, some scanning lines may have flickering and uneven energy. Due to the dense scanning lines, it is difficult to determine the position of abnormal scanning lines. It is difficult to quickly solve system abnormalities, so a scanning and debugging method is needed, which can quickly scan the abnormal scanning lines in the image and enlarge them for debugging by developers

Embodiment 1

[0018] Embodiment 1: An alignment scanning method of an ultrasound system in this embodiment, a frame of abnormal ultrasound image such as figure 1 As shown, it is composed of 128 scanning lines, and the line number increases from 0 to 127. There are several abnormal scanning lines in the middle that appear flickering and uneven energy. , using the debugging method of fixed line scanning.

[0019] The specific steps are:

[0020] First execute step S1: first select an abnormal image area in a frame of ultrasound image with an abnormal image area, in this embodiment select figure 1 Anomalous image area on the right;

[0021] Then perform step S2: estimate the abnormal scan line by combining the position of the abnormal image area and the line density, use the width of the abnormal image area to estimate the number of abnormal scan lines in this area, and estimate the abnormal scan line number at the center position according to the line density, and determine the abnormal ima...

Embodiment 2

[0026] Embodiment 2: The alignment scanning method of an ultrasound system in this embodiment is different from Embodiment 1 in that: in step S4, after finding the abnormal scanning line in the abnormal image area, return to step S2 and reselect Another abnormal image region in the frame of ultrasound image and locate the abnormal scan line.

[0027] Other methods can refer to embodiment 1.

Abstract

The invention relates to a fixed-line scanning method of an ultrasonic system. The fixed-line scanning method comprises the following steps: selecting an abnormal image area of a frame of ultrasonic image; positioning a corresponding abnormal scanning line according to the current abnormal image area; acquiring a scanning control parameter corresponding to the abnormal scanning line; and replacing scanning control parameters of all scanning lines in the frame of ultrasonic image with the scanning control parameter corresponding to the abnormal scanning line, performing scanning again to obtain a frame of new ultrasonic image, and judging whether all the scanning lines are abnormal or not, if not, returning to step S2, re-judging one abnormal scanning line, and if yes, determining that the abnormal scanning line judged in S2 has a problem. According to the fixed-line scanning method, the abnormal scanning lines in the image can be quickly scanned and positioned, and the abnormal scanning lines are amplified so as to facilitate debugging of research and development personnel.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic scanning, and in particular relates to an alignment scanning method and a debugging method of an ultrasonic system. Background technique [0002] Each transmission and reception of the ultrasound system requires various transmission and reception parameters to guide the control action of the FPGA, such as the transmission delay, transmission waveform, and transmission aperture size of the current transmission, the reception delay parameters used in the current reception, Apodization coefficient, etc. These parameters related to transmission and reception are called scanning control parameters. The scan control parameters for each transmission and reception are different, and all the scan control parameters required to form a complete ultrasound image are called a scan control frame. A complete frame of ultrasound image consists of multiple scan lines, and each scan line has its corresponding ...
