Patent ID: 8605861

Claim:
A filtered medical image display system, comprising: an interface processor for receiving data indicating, image characteristics of a first medical image obtained using a medical imaging device and in the absence of an image filter, wherein the first medical image comprises a positioning image obtained using a first X-ray radiation dose, and imaging device settings; a computation processor for using the image characteristics data and imaging device settings in, computing a change in image display characteristics occurring in a filtered portion of said first medical image in response to filtering a medical imaging beam responsible for producing said filtered portion of said first medical image, and determining an adjustment of image display characteristics of said first medical image by scaling image display characteristics of said first medical image including said filtered portion, to increase brightness of said first medical image having brightness subtracted in said filtered portion, in response to the computed change in image display characteristics occurring in said filtered portion in response to said filtering; and a display processor for using the determined adjustment in said image display characteristics of said first medical image in generating data representing a second medical image, wherein the second medical image comprises a diagnostic image obtained using a second X-ray radiation dose higher than the first X-ray radiation dose.
