Abstract
The present disclosure provides a system and method for medical imaging. The method includes obtaining a first reconstructed image of a target subject; and generating a target reconstructed image of the target subject by inputting the first reconstructed image into a trained deep learning model. An image quality of the target reconstructed image is higher than that of the first reconstructed image.

A method for medical imaging, comprising:
- obtaining a first reconstructed image of a target subject;
- and
- generating a target reconstructed image of the target subject by inputting the first reconstructed image into a trained deep learning model, wherein an image quality of the target reconstructed image is higher than that of the first reconstructed image, wherein the trained deep learning model includes:
- a plurality of primary feature extraction blocks that are connected in series, and a plurality of secondary feature extraction blocks.

A method for medical imaging, comprising:
- obtaining a plurality of sets of initial scanning data, each of the plurality of sets of initial scanning data being acquired by performing a circle of full-angle scanning on a target subject using an imaging device;
- for each of the plurality of sets of initial scanning data, generating initial reconstruction data by performing reconstruction based on the set of initial scanning data;
- generating a third reconstructed image corresponding to a target time point by performing, in a chronological order, interpolating based on the initial reconstruction data of the plurality of sets of initial scanning data;
- and
- generating a first reconstructed image corresponding to the target time point based on the third reconstructed image and a portion of the plurality of sets of initial scanning data.
