Abstract

The invention provides an ultrasonic scanning method. The method includes the steps of emitting N groups of ultrasonic signals at N different angles towards an object and receiving the N groups of ultrasonic signals reflected and / or scattered from the target; converting the N groups of ultrasonic signals into N ultrasonic input images; subjecting the N ultrasonic input images to a binarization algorithm so as to obtain N binary images; subjecting the N binary images to comparison so as to judge whether or not at least one of the N binary images has noise; if yes, filtering the noise from the i-th binary image corresponding to the i-th binary image; and synthesizing the N ultrasonic input images into an ultrasonic output image. Each group of ultrasonic signals correspond to one of the N different angles, with N being a positive integer greater than 1 and i being a positive integer less than or equal to N.

Description

technical field [0001] The present invention relates to an ultrasonic scanning method and an ultrasonic scanning system, in particular to an ultrasonic scanning method and an ultrasonic scanning system capable of effectively filtering noise. Background technique [0002] Because ultrasonic scanning has the characteristics of not destroying the structure of materials and human cells, it is widely used in the field of materials and clinical medical testing. Because composite images can provide better resolution, composite images have been widely used in ultrasonic scanning systems. The technical principle of the composite image must first transmit and receive ultrasonic signals from multiple different angles, and then synthesize the ultrasonic images corresponding to the multiple different angles into a composite ultrasonic image. However, ultrasonic images generated by ultrasonic signals emitted and received from oblique angles often produce side lobes, artifacts, or other n...
