A method for processing image data, comprising:
- obtaining first positron emission tomography (PET) scan data;
- performing a reconstruction operation based on the first PET scan data to generate a first initial PET image;
- and
- obtaining first information of a region of interest by segmenting the first initial PET image using a segmentation model.

A method for determining a kinetic parametric image, comprising:
- obtaining at least two sets of scan data of a target region, time information corresponding to the at least two sets of scan data being different;
- obtaining a region of interest of the target region by inputting the at least two sets of scan data into a trained segmentation model;
- determining one or more values of one or more kinetic parameters based on the region of interest and a pharmacokinetic model, the one or more kinetic parameters being related to metabolic information of a tracer in the target region.
