Abstract: A method for converting scan information of computed tomography scanner into bone parameters includes the steps of: providing a computed tomography scanner; providing a test object and two phantoms of known components; using the computed tomography scanner to obtain a corresponding test object scan information and two phantoms scan information; receiving the test object scan information and the two phantoms scan information through a computing device; using the computing device to calculate an energy attenuation coefficient of the computed tomography scanner through a physical function model including the known components and the two phantoms scan information; providing the computing device with an energy correction coefficient; and enabling the computing device to obtain a bone parameter of the test object through a true relationship function that includes the energy attenuation coefficient, the test object scan information and the energy correction coefficient.

Abstract: A method of medical image registration is to be implemented by a computer device, and includes steps of: obtaining an ultrasound target image corresponding to an area of interest in an ultrasound image; for each of multiple computed tomography (CT) images, obtaining a CT candidate image that corresponds to an area of interest in the CT image; for each of the CT candidate images, calculating a similarity between the CT candidate image and the ultrasound target image; making one of the CT candidate images that corresponds to the greatest similarity among the CT candidate images serve as a CT target image; and performing image registration on the ultrasound target image and the CT target image.
