ACFs relevant for PET quantification. Attenuation maps, ACFs, and acquired emission data (after gap filling) in case of headphones and RF coil. The sinograms (ACFs and emission data) correspond to the same transversal plane as used for illustration of the attenuation map. The solid green line specifies the manually segmented emission sinogram support. Only LORs located within the emission sinogram support contribute to the PET image of the phantom/patient. This is not the case for the LORs illustrated by the dashed green lines, which penetrate only the hardware but not the phantom/patient. Their approximate location within the sinogram space is given by the dashed green circles
