Abstract

The invention provides a medical image processing method, system and device and a computer readable storage medium. The method comprises the steps that first modal image data of a target object is acquired; based on the first modal image data of the target object, a first image reconstruction algorithm is used for generating an initial attenuation image of the target object; a machine learning model is used for processing the initial attenuation image of the target object to obtain an optimized attenuation image of the target object; according to the optimized attenuation image of the target object, attenuation correction is carried out on the first modal image data of the target object to obtain a first modal image after attenuation correction, or according to the optimized attenuation image of the target object, a second modal image of the target object is determined. The medical image processing method, system and device and the computer readable medium can be used for obtaining themore accurate attenuation image under the situation that a patient is free of additional scanning.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a medical image processing method and system. Background technique [0002] Positron Emission Tomography (PET) is the highest level of nuclear medicine imaging technology today, and it has shown excellent performance in the fields of oncology, cardiovascular disease, nervous system disease research, and new drug development research. PET reconstructs the gamma photon pairs of tracers in the human body to produce images reflecting the metabolic function of the scanned object. However, the resolution of PET is low and cannot provide structural information of the patient, making it difficult to locate the lesion only relying on PET images. Therefore, it is necessary to provide a method for obtaining a structural image of a target object from positron emission tomography data. Contents of the invention [0003] One aspect of the present application provides a medical ima...
