This paper develops a method for automatic colorization of images (or two - dimensional fields presented as images), in order to clearly visualize the intensity level. Medical images like X - ray, CT scan, MRI and Ultrasound images are generally gray images. In these type of appli cations, brightness level are very important for good diagnosis . In generally used pseudocoloring methods intensity information is lost due to simple to one transform. Hence a parametric path in RGB color cube is introduced for preserving the brightness level. The obtained spiral can provide a number of color spectra by altering its parameters. in pseudocored image. This method can also applied on images of higher number of bits. Here this technique is taken as the tool for enhancing the gray medical images. A hybrid scheme is also applied in which a specific window of gray image is psudocolored with a color spectra other than the applied on remaining image. Human beings can only discern a few dozen gray level values while they can distinguish thousands of colors, the use of color for human interpretation could only improve the diagnos is process . It can produce a n image in different color spectras for visualising the medical image clearly and effectively hig hlight the disease areas, which results in better diagnosis .
