Claim One:
1. A nuclear imaging system for generating a nuclear image of an object, the nuclear imaging system comprising: a nuclear imaging system configured to generate nuclear data; one or more computer processors configured to generate an attenuation correction map for use in reconstructing the nuclear data into an attenuation-corrected nuclear image of an object, the one or more computer processors being configured to: reconstruct the nuclear data into a non-attenuation corrected image, apply a watershed segmentation to the non-attenuation corrected image to generate a segmented image including image regions, each corresponding to an element class, determine features of at least one of a) the image regions and b) boundaries between the image regions depending on image values of the non-attenuation corrected image, and assign attenuation values to the image regions based on the determined features to generate the attenuation correction map; a nuclear image reconstruction processor configured to reconstruct the nuclear data into an attenuation corrected nuclear image using the attenuation correction map.
