Abstract

The invention relates to a Dynamic parameter determination method and device, computer equipment and A storage medium. The method comprises the following steps: acquiring at least two groups of scanning data of a target area, wherein time information corresponding to the at least two groups of scanning data is different; inputting the at least two groups of scanning data into a trained analysis model to obtain a region of interest of the target region; determining values of kinetic parameters on the basis of the region of interest and a pharmacokinetic model, the kinetic parameters being related to the metabolic information of the tracer agent in the target region; and reconstructing a dynamic parameter image based on the at least two pieces of scanning data and the value of the kinetic parameter. By adopting the method, the efficiency of acquiring the PET kinetic parameters can be improved.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a method, device, computer equipment and storage medium for determining kinetic parameters. Background technique [0002] With the development of nuclear medicine imaging technology, the use of positron emission tomography (PET) parametric imaging can study the absorption, distribution, metabolism and excretion process of drugs in the human body, and the activity in specific tissues at a specific time. The degree and concentration depend on the physiological characteristics of the local tissue (for example, blood flow, receptor density and affinity, etc.) and the input function of the local tissue (for example, tracer activity in arterial blood or plasma, etc.), PET parameter imaging function can According to the quantitative mathematical description of the relationship between the change of the tracer concentration in the tissue and the above-mentioned various ...
