Abstract

A method comprising: receiving a radiograph of at least a portion of a patient's body, wherein the radiograph is a digital grayscale image, and wherein each pixel of the grayscale image corresponds to a localized exposure index (EI) value; generating an HSL (Hue-Saturation-Lightness) image from the radiograph, wherein: a hue channel and a saturation channel of the HSL image are generated based on the localized EI values, a luminance channel of the HSL image is generated based on the intensity values of the pixels; and transforming the HSL image to an RGB image which conveys both the portion of the radiograph and the localized EI values.
