The invention discloses a CT perfusion imaging method and equipment. The method includes: acquiring perfusion data obtained by CT equipment scanning the current perfusate, the perfusion data representing a time-density curve; using at least two perfusion algorithms to calculate the perfusion data respectively to obtain various perfusion algorithms. Each initial perfusion parameter is used as each initial perfusion parameter; each initial perfusion parameter is calculated according to the weight of various perfusion algorithms to obtain a target perfusion parameter; and a target perfusion image of the current perfusate is formed with the target perfusion parameter. Through the technical solution of the invention, not only the perfusion state reflected by the perfusion image is more accurate, but also the operation is simplified.
Description
technical field [0001] The present invention relates to the technical field of CT equipment, in particular to a CT perfusion imaging method and equipment. Background technique [0002] In medical equipment imaging, perfusion imaging can provide the microcirculatory blood flow status (perfusion status) of living tissues and organs, and reveal pathological or physiological changes such as cerebral infarction and tumors from the cellular level through the perfusion status of tissues and organs, thereby effectively Contribute to the formulation of treatment plans before and after surgery. At present, CT perfusion imaging has become the most commonly used perfusion imaging method due to its low cost, accurate location of lesion area, and universal applicability to all kinds of patients. Specifically, CT perfusion imaging is to dynamically scan the same layer of the selected layer after intravenous bolus injection of contrast agent, so as to obtain the time density curve (Time De...
