The invention discloses a method and device for measuring morphological parameters of an intracranial aneurysm image. The method includes constructing a three-dimensional model including a parent artery and an aneurysm on the parent artery according to intracranial image data. The three-dimensional model includes The virtual parent artery matched with the parent artery and the virtual aneurysm matched with the aneurysm; the neck plane of the virtual aneurysm is determined based on the three-dimensional model, and the target morphological parameters are determined based on the three-dimensional model and the neck plane. The morphological parameters include at least morphological parameters of the virtual aneurysm. It can be seen that the implementation of the present invention automatically measures the morphological parameters of intracranial aneurysms through the three-dimensional model of intracranial image data and the neck plane of the virtual aneurysm included in the three-dimensional model, which can not only improve the measurement of the morphological parameters of intracranial aneurysms The accuracy of the results can improve the measurement speed of the morphological parameters of intracranial aneurysms, thereby providing scientific reference for medical staff when making treatment decisions.
