The invention discloses an intracranial
aneurysm surface area positioning method and device,
computer equipment and a storage medium, and the method comprises the steps: obtaining an intracranial
angiography image, and constructing a three-dimensional
aneurysm blood vessel model based on the intracranial
angiography image; segmenting the three-dimensional
aneurysm blood vessel model along a tumor neck to obtain a three-dimensional aneurysm model, and performing UV expansion on the three-dimensional aneurysm model to obtain a UV plane model; determining a farthest point on the tumor neck boundary space curve along the
blood flow direction and the highest point of the aneurysm on the three-dimensional aneurysm
blood vessel model, taking a mapping point of the highest point on the UV plane model as a pole, taking a
ray formed by the pole and the mapping point of the farthest point on the UV plane model as a polar axis, and establishing a polar coordinate
system on the UV plane model; and positioning and dividing the surface area of the intracranial aneurysm according to the polar coordinates of the area segmentation points of the three-dimensional aneurysm model at the mapping points of the UV plane model. According to the method, the surface area of the intracranial aneurysm can be accurately positioned.
