Abstract
An medical imaging system includes a photodetector array which converts an X-ray image into a series of picture elements arranged in rows and columns of a two dimensional matrix. The picture elements are read from the array on a column by column basis. A spatial filter for the picture elements includes a first filter that applies one filter function to the pixels in each column of the image. The partially filtered pixels are stored in a first memory and then read therefrom row by row in a field interlaced order. The rows of picture elements are sent to a second filter that applies another filter function to each row. The fully filtered picture elements from the second filter either are stored or converted to a video signal for display.
