CT image reconstruction is made up of ______ and ______

CT image reconstruction is made up of ______ and ______

• A. Detectors and Buffers
• B. Slices and Projections
• C. Voxels (volume elements) and Pixels (picture elements)
• D. Vectors and Grids

Answer: (C)

CT image reconstruction focuses on turning measured data into a digital representation of the scanned area. The reconstruction represents the volume as small 3D elements called voxels, with each voxel holding the attenuation value of a tiny region in space. When that volume is viewed as images, each 2D slice is made up of pixels—the picture elements that form the image on the display. So the fundamental building blocks are voxels in 3D and pixels in 2D. The other options describe hardware components or acquisition concepts, not the basic units of the reconstructed image.
