IMAGING METHOD, IMAGING APPARATUS, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/230771
Kind Code:
A1
Abstract:
The present application discloses an imaging method, an imaging apparatus, an electronic device and a computer storage medium. The imaging method comprises: for each preset frequency in a preset frequency range, transmitting a radio frequency pulse of the preset frequency to a target area, the radio frequency pulse being used for exciting water and fat in the target area, such that the water and the fat in the target area are excited to a saturated state; after emitting the radio frequency pulse is finished, collecting a saturation signal corresponding to the preset frequency; comparing the saturation signals corresponding to all the preset frequencies with a pre-collected initial signal to determine a mixed signal of water and fat in the preset frequency range; calculating a first signal of the water; and on the basis of the mixed signal and the first signal, determining a second signal, and on the basis of the spectral distribution of the second signal, generating a fat peak map of the target area, the second signal being a signal of the fat. According to the method, imaging can be directly carried out on the basis of the spectral distribution of the fat signal, and the spatial resolution of an image can be improved.
