METHOD AND APPARATUS FOR SUPER-RESOLUTION USING WOBBLE MOTION AND PSF IN POSITRON EMISSION TOMOGRAPHY

摘要

PURPOSE: A super-resolution photographing device and a super-resolution photographing method using a PSF(Point Spread Function) and a wobble motion in a positron emission tomography are provided to implement an image with super-resolution based on the PSF according to the position of a PET(Positron Emission Tomography) image. CONSTITUTION: A signal classifying unit(110) classifies an input signal applied through the movement of a bed according to the position of a PET. A first image generator(120) generates a first image set by re-composing the classified input signal. A first image set is a low resolution image set. A parameter measuring unit(130) measures the PSF according to the first image set. A second image generator(140) generates second image information by applying super-resolution algorithm based on the PSF.
