Method for making electrode brain gyri scale map

Abstract

The present invention relates to a method for making an electrode scale map, comprising: S1, registering a postoperative CT thin-layer scan of a patient with embedded electrodes, so that the registered postoperative CT and MPR nuclear magnetic sequence are in the same standard space; S2. Segment the cortex of the preoperative MPR NMR sequence, and mark different brain gyri to obtain the cortical segmentation template; S3. Import the postoperative CT, preoperative MRP NMR sequence and the cortical segmentation template into the 3D Slicer software, and adjust the transparency respectively; S4. Use 3D Slicer software to cut the brain image along the long axis of the electrode, so that all electrode points of the electrode are displayed on the same plane of the brain image, and edit the image after screenshots of the brain image displayed on the same plane ; S5. The image editing software imports the blank template, and arranges all the electrodes at the corresponding positions of the blank template at equal intervals in order to obtain the electric-level brain scale diagram.

Description

technical field [0001] The invention relates to a method for making an electrode brain gyrus scale map, and relates to the technical field of epilepsy surgery. Background technique [0002] Epidemiological surveys show that the prevalence of epilepsy in my country is 6.8‰, and at least 20-30% of nearly 10 million epilepsy patients are drug-resistant epilepsy, and these patients need to be considered for surgical evaluation. Stereotactic electroencephalography (SEEG) is an invasive electrophysiological examination method that has been rapidly popularized recently. It plays an important role in the diagnosis, treatment and preoperative evaluation of epilepsy, and is also the main method for precise positioning of the epileptogenic zone. The relatively small number of electrode implants and limited location are the main advantages of SEEG, but at the same time, it also creates a problem. It is difficult to display electrode groups with complex positional relationships in common...

Problems solved by technology

The combination of the two methods can display the electrode position from the whole and part, which conforms to the habit of reading images in the past, but does not conform to the habit of reading EEG pictures.

Since they cannot be combined with the EEG, the two are completely isolated, so when analyzing the EEG, in order to clarify the electrode position of the corresponding lead, the analyst has to repeatedly switch between the EEG, MRI, and CT for interpretation. It is cumbersome, inefficient, and error-prone, which is obviously contrary to the current medical development trend of "precision medicine"
