Abstract
A method for attenuation correction of a phantom image in a PET imaging system includes obtaining raw scan data of a scanned phantom, a non attenuation corrected template image of a stock phantom of like type to the scanned phantom, and an attenuation map of the stock phantom. The method further includes generating a non-attenuation corrected raw image of the scanned phantom based on the raw scan data, registering the template image and attenuation map to the raw image through a rigid image transform, and applying the registered attenuation map to the raw scan data to enable reconstruction of an attenuation corrected final image.
