Abstract

The embodiment of this specification discloses a method and a system for determining a bypass vessel in intracranial and intracranial blood flow reconstruction guided by multimodal information. The scheme includes: obtaining the thin-slice magnetic resonance image of the patient's brain; obtaining the cranial structure model of the patient's brain; obtaining the whole cerebral angiography image of the patient's brain, obtaining the information of the blood vessel structure of the patient's brain; obtaining the cerebral blood flow of the patient's brain Flow perfusion and metabolism images, to obtain the metabolism and perfusion level information of the patient's brain; to obtain the patient's whole brain neuron electrical activity energy spectrum and functional connection topographic map, to obtain the patient's brain neuron activity level information; the skull structure model, blood vessel Structural information, cerebral blood perfusion and metabolism information, and neuron activity level information are fused to obtain a multi-modal stereoscopic image of the patient's brain; according to the stereoscopic image, the surgical area for the patient's cerebral hemispheres is determined, and candidate bypass vessels are determined. By adopting the method of the present invention, the selection accuracy and rationality of candidate bypass vessels can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and system for determining a bypass vessel for intracranial and intracranial blood flow reconstruction. Background technique [0002] In the prior art, intracranial and extracranial blood flow reconstruction (also called cerebral vascular bypass) is a commonly used clinical method for the treatment of ischemic or hemorrhagic cerebrovascular diseases (such as moyamoya disease, intracranial artery occlusion). Its purpose is to anastomose the extracranial artery (the superficial temporal artery commonly used in clinical practice) as the donor vessel with the intracranial artery (recipient vessel, the cortical branch of the middle cerebral artery commonly used in clinical practice) through surgical methods, so as to utilize extracranial blood. It can supply intracranial blood flow, improve cerebral blood perfusion insufficiency, reduce intracranial vascula...
