Abstract

Abstract : In clinics, subdural hematoma is one of the common intracranial hematomas, whose hematoma morphology presents new crescent, and because of simple medicine it usually uses Coniglobus formula to estimate the volume; however, the error is usually larger, and computed tomography generally does not scan the maximum section of the hematoma, that is, the maximum section of scanning layer is often not its actual maximum section; if we bring its value into the Coniglobus formula, it will bring more errors. Therefore, by aid of the maximum section and subsection next to the maximum section of computed tomography images, according to the volume of spherical segment formula, the author derives the formula of calculating the subdural hematoma volume. Then the author builds a model of subdural hematoma with 3-dimensional modeling software and accurately calculates its volume, and compares it with the subdural hematoma volume calculated by the improved formula and the subdural hematoma volume calculated by the Coniglobus formula to verify the accuracy of this method. It has important clinical significance and is of practical value.
