Problems solved by technology

Due to the sensitivity differences in the design or use of ultrasonic probes, the echo signals generated by each array element of the ultrasonic probe may have inconsistent amplitudes, resulting in obvious differences between ultrasonic image lines, resulting in uneven images and affecting the effect of ultrasonic images.

Abstract

The invention provides ultrasonic diagnostic equipment and an ultrasonic imaging method. By obtaining first array element sensitivity or impedance, second array element sensitivity or impedance is acquired; according to the first array element sensitivity or impedance, a first compensation coefficient is determined, and according to the second array element sensitivity or impedance, a second compensation coefficient is determined, wherein the first compensation coefficient is different from the second compensation coefficient; compensation processing is carried out on a first echo signal according to the first compensation coefficient, and compensation processing is carried out on a second echo signal according to the second compensation coefficient; and the first eco signal and the secondeco signal after compensation treatment are subjected to beam synthesis, and are processed to generate an ultrasonic image. Corresponding compensation coefficients are determined according to the sensitivity or impedance of the respective array elements, then the eco signals generated by the respective array elements are compensated to reduce sensitivity or impedance difference between differentarray elements, and space consistency and uniformity of images are improved, thereby improving the final ultrasonic image display effect.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging, in particular to ultrasonic diagnostic equipment and an ultrasonic imaging method. Background technique [0002] Medical ultrasonic imaging diagnostic equipment uses the propagation of ultrasonic waves in the human body to obtain ultrasonic characteristic information of human tissue and organ structures. Current ultrasonic diagnostic systems usually use multi-element probes. In this system, high-voltage pulse waves are loaded on each array element of the probe, and the array elements are excited to generate high-frequency ultrasonic waves, which then form a transmission beam and enter the human body. Each array element of the probe receives the echo scattered or reflected by the human tissue structure, and through beam synthesis, the echo data from each point in the longitudinal direction to each array element are added in phase to form a receiving beam. After processing each receiving beam, a...
