1. A method for segmenting bones on magnetic resonance (MR) images, the method comprising: retrieving an MR image; performing an enhancement process on the MR image to generate a bone enhanced MR image; registering a computer tomography (CT) based bone atlas to the bone enhanced MR image; generating an MR image with bone segmentation by segmenting the bone enhanced MR image using the CT based bone atlas as a mask, and displaying the MR image with bone segmentation on a display.
