Fig. 2From: MLAA-based attenuation correction of flexible hardware components in hybrid PET/MR imagingCT images of headphones and RF surface coil. The headphones are composed of two earpads connected with a flexible headband. The RF coil contains highly attenuating materials with CT values larger than 3071 HU, mandating the use of an extended CT scale. CT grayscale windowing: C=0 HU,W=2000 HUBack to article page
