Abstract

The principle and technique of real-time pseudo-coloring enhancement for medical density images by liquid crystal light valve (LCLV) are discussed in detail. We present a simplied hybrid field effect mode of LCLV, and give the mathematical formula of projection light intensity. With this result, the characteristics of this pseudo-coloring method are discussed and the rule of optimum system is pointed out. Experiments prove our analysis method is effective. We set up a real-time pseudo-coloring system for medical density image, which can be used in practice. Some pseudo-coloring images of X-ray density pictures are shown in this paper.
