METHOD FOR REMOVING A NOISE OF A PET SIGNAL IN A PET-MRI FUSION DEVICE USING MODELING AND A PET SYSTEM IN THE PET-MIR FUSION DEVICE USING THE SAME CAPABLE OF EXTRACTING AN IMAGE WITH AN EXTRACTED PET DIGITAL SIGNAL
METHOD FOR REMOVING A NOISE OF A PET SIGNAL IN A PET-MRI FUSION DEVICE USING MODELING AND A PET SYSTEM IN THE PET-MIR FUSION DEVICE USING THE SAME CAPABLE OF EXTRACTING AN IMAGE WITH AN EXTRACTED PET DIGITAL SIGNAL
PURPOSE: A method for removing a noise of a PET signal in a PET-MRI fusion device using modeling and a PET system in the PET-MIR fusion device using the same are provided to minimize the deterioration of sensitivity by removing disturbance elements.;CONSTITUTION: A PET(Position Emission Tomography) analog signal is converted into a digital signal with a constant sampling frequency(S110). A PET digital signal is grasped through modeling using a sampling point of the PET digital signal(S120). The PET digital signal is extracted to be included in an image composition(S130). The image is composed of the extracted digital signal(S140).;COPYRIGHT KIPO 2012
