Floating surface coils, such as the anterior array coil, are ignored in PET attenuation correction for PET/MR because their position is difficult to determine. This leads to quantitative bias in reconstructed PET images. This study investigates the potential to improve quantitative accuracy in PET when using a new lightweight "AIR Technology" anterior array coil, as compared to the traditional anterior array coil. Metrics of quantification accuracy and error variation were explored with a phantom and clinical study.
