Problems solved by technology

Since the data of 3D vascular images based on CT angiography (CT Angiography, CTA) and MR angiography are reconstructed through computer software post-processing, rather than original data, the spatial resolution of imaging and the accuracy of blood vessel display low, and the accuracy of the resulting 3D cerebrovascular model is also relatively low
In addition, due to the partial volume effect, CT angiography has poor

Embodiment Construction

[0022] Such as figure 1 As shown, the method for printing a 3D model of an intracranial aneurysm based on DSA data includes the following steps:

[0023] Step 101, select a patient with intracranial aneurysm, obtain original image data through DSA examination, and output the image data in DICOM format through PACS software system;

[0024] Step 102, import the output image data (DICOM format) into the professional medical 3D model reconstruction system MIMICS (the version of mimics17 is selected in this embodiment), and the MIMICS software system processes the image data to realize the reconstruction of cerebrovascular data;

[0025] Step 103. In the process of cerebrovascular data reconstruction, divide the data into two parts, one part is the data of the skull part with higher density, and the other part is the DSA cerebrovascular data reconstructed by the contrast agent effect, and the MIMICS software system automatically extracts the DSA brain data. blood vessel data;

Abstract

The invention discloses an intracranial aneurysm 3D (three-dimensional) model printing method based on DSA (digital subtraction angiography) data. The method includes the steps: acquiring original DSA image data and outputting the image date; leading the outputted image date into a medicine 3D model reconstruction system to reconstruct cerebral vascular data; automatically extracting the DSA cerebral vascular data by the 3D model reconstruction system; selecting needed DSA cerebral vascular data model to build a 3D model; trimming the obtained model; printing a cerebral vascular and intracranial aneurysm model by the aid of a 3D printer. The intracranial aneurysm 3D model is more refined and more suitable for an entity model, has a smoother surface and can display tiny branch vessels and provide more important reference for operations.

Description

technical field [0001] The invention relates to a method for printing a 3D model of an intracranial aneurysm based on DSA data, and belongs to the medical field. Background technique [0002] Intracranial aneurysms are mostly abnormal bulges that occur on the walls of intracranial arteries, and are the number one cause of subarachnoid hemorrhage. The mortality rate of this disease is extremely high, and it will cause huge losses to patients and families. Intracranial aneurysms are more likely to occur at the bifurcation of the arterial ring at the base of the brain and its main branches. The part where the aneurysm connects with the parent artery is narrow, which is called the neck of the aneurysm. The most prominent part on the far side opposite to the neck of the aneurysm is the base (roof) of the aneurysm, and the part between the neck and the base of the aneurysm is called the body of the aneurysm ( bag). The vast majority of congenital aneurysms are cystic or berry-sh...
