Embodiment Construction

[0022] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like figure 1 A medical image reconstruction method shown comprises the following steps:

[0024] Step 1: Collect raw medical images, one of which is denoted as Where M and N represent the number of rows and columns of S, respectively, and S uv (u=1,2,...,M,v=1,2,...,N) means the elements of row u and column v of S;

[0025] Step 2: Transform the acquired original medical image, specifically: divide S into sub-matrices p is a positive integer, and MN / p is guaranteed 2 is an integer; do P on S T transformation, where P T : to get the matrix in b j is given by the matrix B j All the columns of are expanded into a column vector in turn;

[0026] Step 3: Set parameters: training stop threshold ε 0 is a real number greater than 0, the maximum number of iterations ζ is a positive integer, and the singular threshold coe...

Abstract

The invention discloses a medical image reconstruction method and system, and a readable storage medium, and the method specifically comprises the following steps: collecting medical image data, carrying out the conversion of the medical image data, and obtaining a reconstruction result through an iterative calculation method. Compared with the prior art, the invention has the advantages that thetruncation kernel norm is adopted, the approximation effect on the rank function is better, the reconstruction precision is high, and the efficiency is high. Since training based on a large amount oflabeled data is not needed, the dependence of the model on labels is reduced.

Description

technical field [0001] The invention relates to the field of medical image reconstruction, in particular to a medical image reconstruction method, system and readable storage medium. Background technique [0002] Medical images are an important basis for clinical diagnosis. For example, ultrasound imaging is a technology that uses ultrasonic beams to scan the human body and processes the reflected signals to obtain images of human organs. Ultrasound imaging methods can be used to determine the extent of lesions, judge the shape of organs, and identify whether the fetus is normal or not. However, due to the poor imaging quality of some ultrasound equipment, especially portable ultrasound equipment, it brings difficulties to doctors' clinical diagnosis and reduces the accuracy of diagnosis. Therefore, it is very important to reconstruct high-quality images based on original images. [0003] In the existing research, CN110084751A discloses an image reconstruction system and me...
