【摘要】：為精確定位術(shù)中硬膜下矩陣式電極的圖像坐標(biāo)和序號(hào),本文提出一種圖像處理的矩陣式電極定位聯(lián)合算法。采用電極逐點(diǎn)擴(kuò)展定位算法,向上下左右逐點(diǎn)擴(kuò)展,確定各個(gè)電極初始坐標(biāo)和序號(hào);采用單電極坐標(biāo)區(qū)域提取算法,確定各個(gè)電極最佳坐標(biāo),從而逐點(diǎn)定位所有電極的圖像坐標(biāo)和序號(hào)。本文研究結(jié)果表明,電極序號(hào)定位準(zhǔn)確率達(dá)100%,電極坐標(biāo)定位誤差小于2 mm。本文研究的算法可以精確定位呈弧形排列的矩陣式電極圖像坐標(biāo)和序號(hào),從而輔助繪制大腦皮層功能映射圖,實(shí)現(xiàn)術(shù)中腦功能區(qū)精確定位,因此今后或可廣泛應(yīng)用于基于皮質(zhì)腦電信號(hào)分析的神經(jīng)系統(tǒng)科學(xué)研究和應(yīng)用。
[Abstract]:In order to accurately locate the image coordinates and serial numbers of matrix electrodes in intradural operation, this paper presents a joint algorithm of matrix electrode location for image processing. The initial coordinates and ordinal numbers of each electrode are determined by using the point-by-point expansion algorithm of the electrode, and the optimum coordinates of each electrode are determined by using the single-electrode coordinate region extraction algorithm. Thus, the image coordinates and serial numbers of all electrodes are located point by point. The results show that the accuracy of electrode sequence number is 100 and the error of electrode coordinate positioning is less than 2 mm. The algorithm studied in this paper can accurately locate the coordinate and ordinal number of the matrix electrode image arranged in arc shape, which can help to draw the functional mapping map of cerebral cortex and realize the accurate localization of the functional area of the brain during the operation. Therefore, it may be widely used in the research and application of neuroscience based on EEG analysis in the future.
