X-RAY IMAGE DATA PROCESSING APPARATUS

摘要

An X-ray image data of a patient into which an X-ray contrast medium is being administered is processed in an X-ray image data processing apparatus so as to obtain the X-ray image data having an improved S/N ratio. The processing apparatus mainly comprises a linear differential filter that is composed of a plurality of multipliers and an adder. The X-ray image data is multiplied by a plurality of differential coefficients, and thereafter the results of these multiplications are summed.
