Abstract

The embodiment of the invention discloses a blood vessel parameter calculation method and device, equipment and a storage medium. The method comprises the steps of determining a to-be-detected grid blood vessel image and a blood flow parameter corresponding to the to-be-detected grid blood vessel image; performing initialization setting on the to-be-detected grid blood vessel image based on the blood flow parameters; and inputting the initialized to-be-detected grid blood vessel image into a pre-trained blood vessel parameter network model to obtain target blood vessel parameters at each gridnode in the output to-be-detected grid blood vessel image. According to the embodiment of the invention, the vascular kinetic parameters are calculated through the vascular parameter network model, the problem of complex calculation of the vascular kinetic parameters is solved, and the calculation efficiency of the vascular kinetic parameters and the accuracy of the calculation result are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of blood vessel imaging, and in particular, to a calculation method, device, device, and storage medium of blood vessel parameters. Background technique [0002] Medical imaging technologies such as Computed Tomography (CT), Magnetic Resonance (MR) and C-arm X-ray machines play an important role in medical diagnosis and treatment. Especially when using digital subtraction angiography (DSA) with a large C-arm to image and analyze blood vessels, the current existing technology mainly uses image segmentation methods to segment blood vessel images so that doctors can clearly The morphological structure of the target blood vessel can be accurately observed, and then it can be judged whether there are problems such as stenosis, plaque and aneurysm in the target blood vessel. Further, through blood flow parameter detection equipment, such as Doppler ultrasound examination equipment, the blood...
