Abstract

The invention relates to an ultrasonic imaging method and an ultrasonic imaging device for realizing high-sensitivity imaging, comprising: performing several combined scans on an object to be detected under normal imaging steps, each combined scan including a first mode scan and a second mode scan; entering into a high-sensitivity Imaging step, at this time the emission voltage of the second mode pulse is adjusted to be higher than the emission voltage of the second mode pulse in the normal imaging step, and the emission voltage of the first mode pulse is adjusted to be lower than that of the first mode pulse in the normal imaging step The transmit voltage of the signal. In the embodiment of the present invention, by adding a high-sensitivity imaging step, the pulse emission voltage in the second mode is increased while the pulse emission voltage in the first mode is decreased, thereby improving the imaging sensitivity.

Description

technical field

[0001] The invention relates to the field of ultrasonic imaging, in particular to an ultrasonic imaging method for realizing high-sensitivity imaging and an ultrasonic imaging device. Background technique

[0002] Medical ultrasonic imaging equipment uses the propagation of ultrasonic waves in the human body to obtain ultrasonic characteristic information of human tissue and organ structures. Ultrasonic imaging equipment usually uses multi-element probes. High-voltage pulse waves are loaded on each array element of the probe, which excites the array elements to generate high-frequency ultrasonic waves and then forms a transmission beam to enter the human body. Each array element of the probe receives echoes scattered or reflected by human tissue structures. , form the receiving beam, and the ultrasonic imaging equipment extracts the information in the ultrasonic echo, and forms various imaging modes for display. Different types of imaging modes correspond to...
