Japanese Patent JP2002523946
Kind Code:
A
Abstract:
An X-ray examination apparatus is provided including: an X-ray image means for providing an X-ray image composed of pixels each having a grey value, and a brightness control system which is coupled to the X-ray image means in order to apply a brightness control signal of the image to the X-ray image means. The brightness control system comprises an X-ray image analyzing means for deriving the brightness control signal from a maximum in the number of times that a grey value occurs in the X-ray image. The apparatus provides optimized brightness in the visual image such that a physician is capable of properly examining changes in weakly absorbing tissues or body parts, such as lungs or the like, thus enabling optimized visual analysis.
