A method and device for fusion display of cerebral cortex electrodes and magnetic resonance images

Abstract

A method and device for fusion display of cerebral cortex electrodes and magnetic resonance images. The method includes: taking the MRI image obtained by MRI scanning before the patient is implanted with intracranial electrodes and the implanted image obtained by CT scanning after the patient is implanted with intracranial electrodes. Post-CT image (S01); register the MRI image and post-implantation CT image in the same coordinate space (S02); extract electrode image information from the registered CT image (S03); extract the electrode image information from the registered MRI Extract cerebral cortex tissue image information from the image (S04); spatially fuse the electrode image information and cerebral cortex tissue image information, and display the spatially fused information through a three-dimensional visualization method (S05); adjust the effect of the three-dimensional visualization display and angle, and convert the adjusted result into the required format for output and storage (S06). Implementing the method and device for fusion display of cerebral cortex electrodes and magnetic resonance images of the present invention has the following beneficial effects: the position information of the electrodes can be obtained.

Description

technical field [0001] The invention relates to the field of information fusion, in particular to a method and device for fusing and displaying cerebral cortex electrodes and magnetic resonance images. Background technique [0002] Surgery is an important means of treating certain brain diseases. The key to surgical treatment is to locate the lesion, that is, to find out the abnormally excited neuron group. At present, intracranial electrodes are considered to be the gold standard for locating lesions. Intracranial electrodes can directly record the EEG activity of the cerebral cortex and internal brain tissue, and can detect abnormal cortical discharges within 1 cm. It has the advantages of clear graphics and high sensitivity. For those cases where the lesion cannot be clearly identified by non-invasive examination, EEG monitoring with intracranial electrodes is a safe and reliable positioning method. [0003] After the electrodes are implanted in the brain, information o...
