发明名称 IMPROVEMENT METHOD FOR MRI IMAGE QUALITY USING MATRIX REGULARIZATION
摘要 PROBLEM TO BE SOLVED: To increase the signal to noise ratio of a magnetic resonance image formed by a system comprising at least two receiving coils. SOLUTION: When a data collecting period is shortened by increasing the space between k-space raster data lines, folding of an image is generated. When its development algorithm is required, in this method, a sensitivity matrix corresponding to a receiving coil is discriminated (200), NMR signal is collected to convert this signal to the pixel intensity of the image (204), a correction matrix is determined, the sensitivity matrix is changed as the function of the correction matrix (208, 210, 212), the changed sensitivity matrix is combined with the intensity matrix to generate an estimated spin density matrix, and a final image is formed by use of the spin density matrix (214, 216, 220).
