ADVANCED AUTOMATIC DIGITAL RADIOGRAPHIC HOT LIGHT METHOD AND APPARATUS

摘要

A method for automatically modifying the rendering of an image based on an analysis of pixel values within a selected region of interest. The method includes: providing a digital input image of digital pixel values and tone scale look-up table (LUT); creating a default rendered image by applying the tone scale lookup table to the input image; displaying the default rendered image; selecting a region of interest from the input image; computing the histogram of the pixel values within the region of interest; creating a bright light image by remapping the pixel values within the region of interest based on an analysis of the histogram and the tone scale table; wherein the tone scale lookup table has been adjusted by one or more of increasing or decreasing the overall contrast, and of reversing the polarity of the tone scale LUT; and overlaying the bright light image on default rendered image.
