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 that an original blood vessel image iscollected, and a blood vessel grid matrix is determined based on the original blood vessel image; and blood vessel parameters corresponding to the original blood vessel image are determined accordingto the blood vessel grid matrix and a pre-trained blood vessel parameter network model. According to the embodiment of the invention, the blood vessel grid matrix is determined based on an original blood vessel image; according to the blood vessel grid matrix and the pre-trained blood vessel parameter network model, the blood vessel parameters corresponding to the original blood vessel image are determined, the problem that the blood vessel parameter calculation process is complex is solved, the training precision of the blood vessel parameter network model can be improved by adopting the blood vessel grid matrix to represent the original blood vessel image, and then the calculation accuracy and precision of the blood vessel parameters 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 techniques such as Computed Tomography (CT) and Magnetic Resonance (MR) play an important role in medical diagnosis and treatment. Especially when medical imaging technology is used 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 observe the morphological structure of target blood vessels, and then judge whether the target blood vessels are There are problems such as stenosis, plaque, and aneurysm. Furthermore, if the doctor wants to further understand the hemodynamic parameters corresponding to the blood vessel image, such as flow resistance, he needs to obtain the physiological parameters of ...
