1. A method for locally enhancing image data represented as pixels having CT numbers, the image data including bony structures, comprising: segmenting pixels within the image data into areas based on the pixel's CT number using a computer, a first area representing a combination of soft tissue and bones having a first density and a second area representing bones having a second density that is greater than the first density; identifying a subset of pixels based on their locations within the second area representative of the bones; applying an enhancement to the subset of pixels within the second area to create an enhanced dataset; and generating a locally enhanced image based on the image data and the enhanced dataset using the computer.
