Disturbance noises in medical X-ray imaging systems consist of inherent and quantum noises
which obey random Gauss and Polsson distributions
respectively. This paper theoretically provided an optimum threshold selection method for medical X-ray images filter. Through practical process of CT images
medical X-ray images filter based on minimum even-square error has been accomplished in this work.
