Abstract
A reconstruction method of an Emission Computed Tomography image, an apparatus, a device, and a storage medium are provided in the present disclosure. The method includes: acquiring a first ECT image sequence, inputting the first ECT image sequence into a trained intermediate frame prediction network to obtain an estimated second ECT image sequence, and reconstructing a target second ECT image sequence based on the estimated second ECT image sequence serving as a prior image. Temporal resolutions of both the target second ECT image sequence and the estimated second ECT image sequence are higher than that of the first ECT image sequence.
Claims20
A reconstruction method of an Emission Computed Tomography (ECT) image, comprising:
- acquiring a first ECT image sequence;
- inputting the first ECT image sequence into a trained intermediate frame prediction network to obtain an estimated second ECT image sequence;
- and
- reconstructing a target second ECT image sequence based on the estimated second ECT image sequence serving as a prior image, wherein temporal resolutions of both the target second ECT image sequence and the estimated second ECT image sequence are higher than that of the first ECT image sequence.
A reconstruction method of an ECT image, comprising:
- acquiring ECT image data;
- obtaining a first ECT image sequence by image reconstruction based on the ECT image data, wherein the first ECT image sequence comprises a plurality of first ECT images corresponding to a plurality of first timestamps;
- generating a plurality of estimated second ECT images based on the first ECT image sequence, wherein a plurality of second timestamps corresponding to the plurality of estimated second ECT images are distributed at intervals with the plurality of first timestamps;
- and
- reconstructing a target second ECT image based on the plurality of first ECT images and the plurality of estimated second ECT images.
