A novel acoustic noise shield constructed of clear acrylic has been developed and evaluated. The results suggest that: 1) it is effective for MR acoustic noise reduction, 2) PET image quality exceeds ACR accreditation testing standards with the proposed acoustic shield in use, showing its compatibility with PET imaging, 3) there is a small impact on PET SUV which can be compensated with attenuation correction, and 4) it does not cause claustrophobia.
