Method and system for generating virtual CT(Computed Tomography) image and attenuation-corrected PET(Positron Emission Tomography) image based on PET image

摘要

Disclosed is a method and system for generating a virtual CT image and attenuation correction PET image based on PET image. A method of generating a virtual CT image and attenuation correction PET image based on a PET image includes (a) a network learning unit performing machine learning based on a PET image and a CT image included in the PET / CT data; (b) a CT image generation unit receiving a PET image, and generating a virtual CT image from the received PET image based on the machine learning resu And (c) an attenuation correction map generation unit generating an attenuation correction PET image from the virtual CT image.
