Figure Lengend Snippet: PCD-CT images from the image uniformity module of the ACR CT accreditation phantom. The mean CT number in the ROIs, and the CT number difference between the peripheral ROIs and the central ROI were within the ±5HU limit for the ACR image uniformity criteria. Display FOV = 210 mm, matrix size = 512 × 512, reconstructed with IR (strength 3), Br44 kernel at 3.0 mm slice thickness. Window width/level = [400/40] HU
