| description | The invention provides an intracranial aneurysm detection method, which comprises the following steps of: extracting bone and blood vessel parts from original CTA (Computed Tomography Analysis) data, and performing three-dimensional reconstruction to obtain a three-dimensional head model; performing six-dimensional cutting and projection on the three-dimensional head model to obtain six groups of two-dimensional pictures; detecting the six groups of two-dimensional pictures to obtain two-dimensional positions of the aneurysm in different directions; and fusing the two-dimensional position of the aneurysm to determine the position of the aneurysm in a three-dimensional space. According to the method, through three-dimensional reconstruction of the skull and the blood vessel, the characteristics of the aneurysm are enhanced, so that the aneurysm is easy to identify by the target detection model, the success rate of aneurysm detection is further improved, and small blocks only containing the aneurysm are sent in |
