Abstract

The invention relates to the technical field of image processing, in particular to an intracranial vessel bounding box automatic planning method and an intracranial vessel bounding box automatic planning device, wherein the method comprises the following steps that: the position of an interested blood vessel in the Willis circle is located on the basis of head CTA three-dimensional volume data, wherein the interested blood vessel is the middle cerebral artery, the anterior cerebral artery or the basilar artery; when the interested blood vessel is the middle cerebral artery, the direction of the artery is analyzed according to the position of the middle cerebral artery, and a corresponding Willis circle bounding box is planned by aiming at different observation directions; when the interested blood vessel is the anterior cerebral artery, the Willis circle bounding box in the observation direction from the front side to the back side is planned according to the position of the anterior cerebral artery; and when the interested blood vessel is the basilar artery, the Willis circle bounding box in the observation direction from the back side to the front side is planned according to the position of the basilar artery. The technical scheme can realize the automatic planning of the bounding box and has the advantages of high planning efficiency and high planning precision.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an automatic planning method and device for intracranial blood vessel bounding boxes. Background technique [0002] The circle of Willis area is an important structure of intracranial blood vessels, and it is also a high-incidence area of ​​intracranial arterial vascular lesions. Doctors need to observe the position, structure and direction of blood vessels in the circle of Willis area according to the three-dimensional rendering results of local CTA three-dimensional volume data. And other characteristics, in order to realize the diagnosis of intracranial arterial vascular diseases. [0003] Since the area of ​​the Circle of Willis is completely blocked by the high-density skull, in clinical practice, in order to observe the blood vessels in the Circle of Willis in the 3D rendering results, the doctor needs to manually plan the bounding box containing the Circle...
