Adding false color to grey-scale x-ray images - help!

[frasesmo]

I've my dissertation next year, and would like to investigate the use of airport style x-ray images in radiological x ray images. The airport style images colourise pixels of a greyscale image based on their darkness (ie. black-->green, grey---->orange, light----->blue).

This mean I need some help please on turning about 20-30 of greyscale images such as:





To images which use colour in this style:

(as you can see, dense things - which would represent bone - are blue; medium things - representing the soft tissue - are orange; and thin/'soft' things - representing air or fluid - are green).
Is there a way in which I can do this easily to 20 images- such as to assign pixels along the greyscale to different colours?

Thank you!

There are several ways to do this, but here's a good place to start: Google {Photoshop tutorial "gradient map"}

If u have any questions after working through a couple of the tutorials, don't hesitate to ask.

Even better, because Photoshop is really designed for artists, not scientists or technologists, if u know how to program in Matlab, Mathematica, or could purchase a scientific graphing software package like "Origin", you will get better & more quantitative results.
