Description

technical field [0001] The invention belongs to the technical field of perfusion image analysis, and in particular relates to a perfusion image analysis method, system, electronic equipment and storage medium. Background technique [0002] CT perfusion imaging (CT Perfusion, CTP) is a continuous CT scan of the region of interest during the rapid intravenous injection of contrast agent, so as to obtain the time-density change relationship of the region of interest, so it can more effectively and quantitatively reflect the local tissue blood. The change of perfusion volume is of great significance to clarify the blood supply of the lesion, and it is widely used in the early detection of cerebral infarction, stroke examination and cerebral ischemia. [0003] At present, the main analysis process of CTP imaging in clinical practice is to use different mathematical models to calculate various perfusion parameter values, and then use the perfusion parameter values ​​to further com...
