METHOD FOR CONVERTING SCAN INFORMATION OF COMPUTED TOMOGRAPHY SCANNER INTO BONE PARAMETERS

摘要

The method for converting scan information of a computed tomography apparatus of the present invention into a skeleton parameter comprises: providing a computed tomography apparatus, a subject, and two phantoms of which components are known; Acquiring scan information of a subject and scan information of two phantoms corresponding to each other through photographing by a computed tomography apparatus; Receiving, by a calculation device, scan information of a subject and scan information of two phantoms; Calculating, by the computing device, an energy attenuation coefficient of the computed tomography apparatus through a physical function model corresponding to the two phantoms and including a known component of the two phantoms and scan information of the two phantoms; Providing an energy correction coefficient to a calculation device; And obtaining, by the computing device, a skeleton parameter of the subject through a truth relationship function including an energy attenuation coefficient of the computed tomography apparatus, scan information of the subject, and an energy correction coefficient.
