System and method for diagnostic and treatment

A system, comprising:

• a non-transitory computer-readable storage medium storing executable instructions, and
• at least one processor in communication with the non-transitory computer-readable storage medium, when executing the executable instructions, causing the system to implement a method, comprising:
• obtaining first image data relating to a region of interest (ROI) of a first subject, the first image data acquired by a first device, the first image data corresponding to a first equivalent dose level;
• obtaining a model for denoising relating to the first image data;
• determining, based on the first image data and the model for denoising, second image data corresponding to an equivalent dose level higher than the first equivalent dose level;
• determining, based on the second image data, information relating to the ROI of the first subject;
• obtaining information relating to the ROI of the first subject from a treatment plan of the first subject;
• and
• performing a delivery of a treatment radiation beam based on the determined information relating to the ROI of the first subject and the information relating to the ROI obtained from the treatment plan of the first subject.
