Contrast adjustment of a decomposed X-ray image relative to the contrast of another X-ray image

摘要

An X-ray system 100 uses a display (114) to display pictures (124) generated in response to an X-ray first range of energy levels and an X-ray second range of energy levels different from the first range of energy levels. Pictures resulting from a substantially single range of X-ray energy levels also are displayed. A source (102) of X-rays transmits X-rays at the first range of energy levels through an object (106) to create in an image sensor (108) a first image and transmits X-rays at the second range of energy levels through an object to create a second image in the image sensor. A processor (110) calculates a first decomposed image from the first and second images according to a first decomposition algorithm, calculates a second decomposed image from the first and second images according to a second decomposition algorithm and calculates a contrast adjusted image in response to the first and second decomposed images. The first picture is displayed in response to the contrast adjusted image and the second picture is displayed in response to the first image.
