WebMathematically, a measurement made by a CT detector is proportional to the sum of the attenuation coefficients that lie along the ray defined by the pencil-beam of x-rays, hence the term raysum. The CT scanner, being an inherently electronic imaging device, produces a digital image that consists of a square matrix of picture elements, i.e. pixels.
