Ultrasonic imaging noise reduction method and ultrasonic imaging equipment

Abstract

The invention discloses an ultrasonic imaging noise reduction method and ultrasonic imaging equipment. The noise reduction method comprises the steps that when it is judged that the ultrasonic imaging device meets a preset precondition, outputting an experiment beam trigger signal, and controlling at least two ultrasonic units located at different transverse positions to emit experiment beams to execute empty scanning; extracting at least two groups of calibration beams which represent the same transverse position and correspond to the experimental beams, analyzing detection data of the calibration beams at preset depths, and correspondingly obtaining at least two groups of sampling data; calculating to obtain standard noise data according to a preset discrete relational expression and the sampling data; and performing noise reduction on the ultrasonic imaging process by using the standard noise data. The ultrasonic imaging noise reduction method has the technical effects of high noise reduction speed and high adaptive degree, meanwhile, the algorithm process is simpler, the characteristics of the formed wave beams are fully utilized, and the noise reduction effect is more obvious when the method is applied to ultrasonic imaging of parallel receiving wave beam forming.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to an ultrasonic imaging noise reduction method and ultrasonic imaging equipment. Background technique [0002] In ultrasound imaging, it is often necessary to artificially adjust parameters such as imaging focus, imaging depth, gain, and dynamic range to improve image quality. Compared with other imaging modalities, noise in ultrasound imaging is the main problem that causes poor image quality. Existing ultrasound imaging equipment is often equipped with structures such as knobs, and the operator needs to manually adjust the relevant parameters of ultrasound imaging according to the problems that appear in the screen, thereby reducing the impact of noise on the image, but this adjustment method relies too much on the operator's experience , it is also difficult to achieve self-adaptation in the face of different operating environments, and at the same time, it also has t...
