ABSTRACT:
An array of Radon transform processors accepts signals representative of the x and y positions of each pixel of an image together with signals representative of the magnitude or brightness of the image. Each Radon transform processor of the array is associated with one value of .theta., an angle relative to the x-axis, and each processor is associated with a different .theta.. Each radon transform processor multiplies the current value of x by cos .theta. and the current value of y by sin .theta., and adds the products to produce the value of rho, the distance from the image center along a line at angle .theta., at which each pixel contributes to a line integral. A memory stores the current pixel's magnitude by updating the line integral associated with the current value of rho by adding the pixel magnitude. When all pixels of the image have been evaluated, the memory of each processor of the array is read in sequence, and the value of the line integral for each value of rho is read from each memory. The Radon transform may be processed. A backprojection processor performs an equivalent systolic image generation from the processed Radon transform.
