摘要： An automatic calculation method of gray-to-white-matter ratio for head computed tomography of patients with cardiac arrest is disclosed and includes an image registration step, a K-means segmentation step, a segmentation refinement step and a GWR calculation step. Measure the gray-white-matter ratio through brain computed tomography early after cardiac arrest to automatically identify the corpus callosum, caudate nucleus, putamen, and posterior branch of the internal brain cyst. It is a 3D three-dimensional structure rather than a manually selected flat circular area to evaluate the effectiveness of predicting neurological prognosis at discharge.
