Abstract

The invention discloses a medical imaging method and system. The method comprises the following steps that: obtaining the medical image scanning data of an area of interest, wherein the medical imagescanning data corresponds a plurality of time phases; on the basis of the medical image scanning data of the plurality of time phases, obtaining the low-resolution images of the plurality of time phases; taking one time phase in the plurality of time phases as a reference time phase; on the basis of the medical image scanning data, obtaining the high-resolution image of the reference time phase; independently obtaining the sports field, which is relative to the low-resolution image of the adjacent time phase, of the low-resolution image of each time phase; and according to the high-resolutionimage of the reference time phase and the sports field, determining the high-resolution images of other time phases except the reference time phase. By use of the embodiment of the invention, the problem in the prior art in the that much time is consumed and the imaging time of the imaging method is lowered can be solved, and the clinical experience of patients and doctors can be improved.

Description

technical field

[0001] Embodiments of the present invention relate to image processing technologies, and in particular to a medical imaging method system. Background technique

[0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) utilizes the phenomenon of nuclear magnetic resonance to excite the spin nuclei in human tissues or organs by applying radio frequency pulses, and then receive the electromagnetic signals released by the spin nuclei to reconstruct the image information of human tissue, with ion-free The advantages of radiation, multi-contrast imaging and high soft tissue contrast have become one of the important tools for clinical medical imaging examination. The data collected during the magnetic resonance imaging process is called k-space data, and the magnetic resonance image can be obtained by reconstructing the k-space data. Dynamic imaging obtains a series of time-related k-space data through continuous and repeated scanning of a specific imag...
