Three elements of dr and CT imaging

The basic unit of CT image is called voxel. A voxel is a unit of volume, which has three elements, namely, length, width and height. According to the thickness of the fault and the size of the matrix, the minimum unit of volume that CT can scan; Pixel is the smallest unit of CT image, and the corresponding voxel, the size of voxel is expressed as pixel in CT image. The smaller the pixel, the higher the resolution of the image.
