FIELD: image forming device.
SUBSTANCE: method comprises steps of generating an attenuation map from an anatomical image data set acquired from a subject; reconstructing an emission image data set acquired from subject to generate an emission image, reconstructing including correcting for attenuation of emission radiation in subject using attenuation map; calculating a value for a quality assurance metric quantifying alignment of attenuation map with emission image; subsequent to storing, retrieving an instance of emission image and an instance of calculated quality assurance metric from image storage; and displaying or printing emission image together with calculated quality assurance metric.
EFFECT: more accurate generation of emission image.
