Image processor

Abstract

An apparatus for processing image data of a computerized tomography system having image data acquisition and main storage devices is provided. The image processing apparatus includes an image processor memory for storing image data and a plurality of operation means having processing apparatus for sequentially performing processing operations on the image data. The apparatus further includes a process controller for providing the image processor memory and the operation means with control data specifying the processing operations to be sequentially performed by the plurality of operation means and for generating sequence selection data. The apparatus also includes a sequencer means for selecting the sequence in which the processing operations are to be performed in accordance with the sequence selection data. The image processing apparatus permits selective interconnection of the image processor memory and the plurality of operation means under control of control data comprising a program to perform processing functions. Alternative schemes of interconnection may be utilized to perform different processing functions. The image processor and plurality of operating means are arranged in parallel. Accordingly, additional operating means may be readily added to the image processing apparatus to enhance the capability of the apparatus. Functional checks are performed on the inputs and output of the image processor memory and each of the operating means by a process controller.
