Embodiment 2

[0091] This embodiment provides an ultrasound image contrast and lateral resolution optimization system, including:

[0092] The original image acquisition component is used to acquire N pieces of original ultrasonic echo images;

[0093] The image smoothing processing component is used to smooth the N original ultrasonic echo images acquired by the original image acquiring component in units of pixels to obtain an echo data matrix, and transmit the echo data matrix to the data processing component;

[0094] The data processing component is used to receive and process the smoothed echo data matrix, and calculate the covariance matrix of the echo signal; it is also used to add white noise to the covariance matrix of the echo signal, and calculate the white noise added Eigenvalues ​​and eigenvectors of the covariance matrix;

[0095] The image generation component constrains the smoothed echo data matrix by using the maximum eigenvalue of the covariance matrix added with the wh...

Abstract

The invention relates to an ultrasonic image contrast and lateral resolution optimization method, which belongs to the technical field of ultrasonic image processing and solves the problem of poor image contrast and lateral resolution obtained by the existing ultrasonic image processing method. The optimization method includes the following steps: using an ultrasonic transducer to obtain N original ultrasonic echo images; performing smoothing processing on the N original ultrasonic echo images in units of pixels to obtain an echo data matrix; The echo data matrix, calculate the covariance matrix of the echo signal; add the white noise signal in the covariance matrix of the echo signal, calculate the eigenvalue and eigenvector of the covariance matrix of the added white noise signal; use the added white noise signal The maximum eigenvalue of the covariance matrix of the smoothed echo data matrix is ​​constrained to obtain the final ultrasonic echo image. The steps of the invention are simple, easy to operate, and can remarkably improve the contrast and lateral resolution of the ultrasonic image.

Description

technical field [0001] The invention relates to the technical field of ultrasonic image processing, in particular to a method for optimizing the contrast and lateral resolution of an ultrasonic image. Background technique [0002] Ultrasound imaging has the characteristics of strong transmission ability and little harm to the human body, and has become one of the most important medical diagnostic techniques. Ultrasonic imaging is a method and technology that uses ultrasonic waves to irradiate a subject, and obtains internal information of the subject's tissue and structure by receiving and processing echoes that carry information about the internal tissue or structure of the subject. Ultrasound imaging has the advantages of low price, good real-time imaging, and no harm to patients. Human tissues such as muscle, fat, spleen, stomach, etc. have similar acoustic impedance, and the ultrasonic echo energy reflected by each tissue is similar. Therefore, high-contrast ultrasonic ...
