CT-scan images

DICOM 16-bit greyscale images. The pixel value, expressed in Hounsfield units (HU). The pixel resolution of each horizontal (X) and vertical (Y) image is 0.195 x 0.195 mm giving a two-dimensional pixel resolution of 0.038 mm². Each slice integrates a thickness (Z) of 0.4 mm, making the voxel (volume) resolution of 0.0152 mm³. The pixel value, expressed in Hounsfield units (HU), represents the linear attenuation of the X-rays, which depends mainly on the density of the material.
