Problems solved by technology

[0005] The existing technology uses the human body physical simulation model to establish the gold standard to achieve quantitative testing, but due to the high price of the human body physical simulation model, the popularity rate is not high
In addition, when using the physical simulation model of the human body, CT scanning needs to be continuously performed during the quantitative test, so it brings a lot of inconvenience to the verification of the algorithm

Abstract

The invention provides a simulation method and a quantitative test method of liver perfusion. The simulation method of liver perfusion includes the steps that a liver model is built, wherein the input of the liver model comprises at least one contrast agent concentration curve input to the liver model and weight coefficients corresponding to the contrast agent concentration curves, the contrast agent concentration curves are dominant parameters, and the weight coefficients corresponding to the contrast agent concentration curves are hidden parameters; a hepatic cell contrast agent concentration curve of the liver model is acquired according to different combinations of the hidden parameters and the dominant parameters and serves as the output of the liver model to simulate liver perfusion. The quantitative test method of liver perfusion is carried out based on the simulation method of liver perfusion. According to the simulation method and the quantitative test method of liver perfusion, cost is low, and operation is simple.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a simulation method of liver perfusion and a quantitative test method of liver perfusion. Background technique [0002] Perfusion refers to the function of blood to transport oxygen and other substances carried by blood to surrounding tissues through the network of capillaries. Hepatic perfusion refers to the process in which blood passes through the abdominal aorta and hepatic portal vein, and the oxygen and other substances in it are transported to the liver tissue for utilization or transformation, and it is generally equated with the blood flow process. [0003] Electronic computer X-ray tomography technique (CT) perfusion imaging is to scan the arterial layer of the selected layer after intravenous injection of contrast agent to obtain the time-density curve of each pixel in the layer (time-density curve, TDC), and then according to the curve, calculate perfusion parameters s...
