strengthen = to make stronger
strong, used like sara used it could equally have been a typo for storing as well as "make stronger"

To make edges more contrasty, use a high boost filter:
kernel = [-1,-1,-1;-1,17,-1;-1,-1,-1]/9;
highBoostFilteredImage = imfilter(double(grayImage), kernel);
imshow(highBoostFilteredImage, []);
That's one way, anyway. There are others.

After reading your "Answer" I really don't know what you want to do. Perhaps you can find a paper here that did the same thing you would like to do: http://www.visionbib.com/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models
