Embodiment 1
[0096] Embodiment 1 provides a semi-automatic measurement method for intracranial aneurysm morphological parameters, according to figure 1 As shown, the first mask combination of a single aneurysm is obtained through the fully automatic preprocessing module; based on the first mask combination of a single aneurysm, the first aneurysm diameter plane is obtained through the automatic extraction module of tumor diameter plane and blood flow direction and the first blood flow direction vector; based on the first tumor diameter plane, the first blood flow direction vector and the aneurysm mask in the first mask combination, according to the calculation rules of each parameter value in the parameter information, through the core calculation module Acquiring the parameter information of the aneurysm; based on the pre-defined conditions of the circumscribed rectangular frame of the aneurysm, according to the aneurysm mask in the first aneurysm diameter plane, the first blood flow direc...
Embodiment 2
[0098] Embodiment 2 provides a semi-automatic measurement method for intracranial aneurysm morphological parameters, according to figure 2 As shown, the method includes:
[0099] A1. Based on the first mask combination of a single aneurysm, the first aneurysm diameter plane and the first blood flow direction vector are obtained, specifically:
[0100] In this embodiment, a cube convolution kernel with a side length of 3 voxels is used to perform an expansion operation on the aneurysm mask in the first mask combination, and the result of the expansion operation is combined with the blood vessel mask in the first mask combination The overlapping voxels are used as intersection points, and all intersection points are obtained;
[0101] In this embodiment, the geometric center of the intersection point is calculated, and the geometric center is used as the estimated center of the tumor body; the estimated center of the tumor body is used as the center, and an area of the same ...
Embodiment 3
[0147] Embodiment 3 provides a semi-automatic method for measuring morphological parameters of an intracranial aneurysm, the method comprising:
[0148] The first mask combination is the connected domain information of a single aneurysm mask extracted in advance from the three-dimensional medical image to be analyzed and the connected domain information of the blood vessel mask to which the single aneurysm mask belongs, specifically:
[0149] In this embodiment, the three-dimensional medical image to be analyzed is segmented by an automatic segmentation algorithm to obtain multiple first aneurysm masks and multiple first blood vessel masks; one first blood vessel mask matches one first aneurysm mask code;
[0150] In this embodiment, for a first aneurysm mask and an associated first blood vessel mask, the first aneurysm mask and the first blood vessel mask are divided into connected domains, and the first aneurysm mask and the first blood vessel mask are obtained. The connect...
