A method of segmenting CT scan data comprises transforming intensity data into transformed data values. In a first option, the method includes convolving the CT scan data with a mask to obtain energy data wherein the mask has band pass filter characteristics, generating a histogram of the energy data and segmenting the CT scan data based on energy values in the generated histogram. In a second option, the method includes transforming the intensity data into Hounsfield scale data, and segmenting the image based on predefined Hounsfield scale values.
