Title:
IMAGE RECONSTRUCTION METHOD, IMAGE PROCESSING DEVICE, AND DEVICE WITH STORAGE FUNCTION
Document Type and Number:
WIPO Patent Application WO/2021/184389
Kind Code:
A1
Abstract:
Disclosed are an image reconstruction method, an image processing device, and a device with a storage function. The image reconstruction method comprises: obtaining an original image; obtaining input image data according to the original image; performing, on a generator network, a first mapping operation on the input image data according to a first mapping function so as to obtain output image data; and forming a reconstructed image according to the output image data. In the present invention, on the generator network, the first mapping operation is performed on the input image data of the original image according to the first mapping function so as to obtain the output image data, thereby directly implementing image reconstruction, so that the image of a radioactive tracer in a low dosage can be clearly presented, facilitating clinical diagnosis of doctors; since the volume of data acquired in a mapping manner is relatively low, the speed of image reconstruction is relatively fast, thus facilitating improving the working efficiency, and since the scanning time required is also relatively short, the occurrence of artifacts can be avoided, thereby improving image quality.
