Abstract
Provided is a method for removing noise of a positron emission tomography (PET) signal in a PET-magnetic resonance imaging (MRI) fusion device without using an MRI radio frequency (RF) shield that degrades image quality. The method includes: receiving a PET output signal from a PET-MRI fusion device and performing analog filtering by removing noise components due to an RF pulse frequency based on the relationship between the frequency of the PET output signal and a magnetic resonance (MR) RF frequency (Larmor frequency); and converting the filtered signal into a digital signal through sampling. The method allows acquisition of molecular-level images without declined performance of a PET detector in MRI environment.
