Method for manufacturing electrode gyrus scale map

Abstract

The invention relates to a method for manufacturing an electrode gyrus scale map. The method comprises the following steps: S1, registering a postoperative CT thin-layer chromatographic scanning of anelectrode-embedded patient to locate the registered postoperative CT and an MPR nuclear-magnetic sequence in the same standard space; S2, performing cortical segmentation on a preoperative MRP nuclear-magnetic sequence, and respectively marking different gyri to obtain a cortical segmentation template; S3, importing the postoperative CT, the preoperative MRP nuclear-magnetic sequence and the cortical segmentation template into 3D slicer software, and respectively performing transparency adjustment; S4, cutting a brain image along the long axis of an electrode by utilizing the 3D slicer software to display all electrode spots of the electrode on the same plane of the brain image, snipping the brain image displayed on the same plane, and performing image edition; and S5, importing image edition software into a blank template, sequentially setting all electrodes on corresponding positions of the blank template in longitudinal direction at equal interval to obtain the electrode gyrus scale map.

Description

Technical field [0001] The invention relates to a method for making an electrode 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 the nearly 10 million epilepsy patients are drug-refractory epilepsy. These patients need to consider surgical evaluation. Stereotactic electroencephalography (SEEG) is an invasive electrophysiological examination method that has been rapidly popularized recently. It occupies an important position in the diagnosis and treatment of epilepsy and preoperative evaluation. It is also the main method for precise positioning of epileptic areas. The relatively small number of electrode implants and relatively few site restrictions are the main advantages of SEEG, but at the same time it also causes a problem. It is difficult to display electrode groups with complex positional relationships in common fl...

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"
