摘要： 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.

摘要： 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: (a1) converting a PET analog signal into a digital signal having a predetermined sampling frequency; (b1) determining whether the resulting PET digital signal is to be included in image reconstruction based on modeling using sampling points of the PET digital signal or an integration value of the PET digital signal; and (c1) extracting only the PET digital signal that will be included in image reconstruction. The method allows acquisition of molecular-level images without declined performance of a PET detector.
