Systems and methods for object imaging

One or more computer-readable storage media having computer-executable instructions embodied thereon for imaging an object, wherein when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

• instruct a detector array to acquire tomographic image data of the object at a plurality of frequencies;
• generate a composite image of the object at each of the plurality of frequencies using the acquired tomographic image data;
• determine a scaling factor for a first material at each of the plurality of frequencies;
• determine a scaling factor for a second material at each of the plurality of frequencies;
• and
• decompose the composite images into a first discrete image and a second discrete image using the determined scaling factors, wherein the first discrete image contains any region of the object composed of the first material and the second discrete image contains any region of the object composed of the second material.

An imaging system for imaging an object, said system comprising:

• a detector array configured to acquire tomographic image data of the object at a plurality of frequencies;
• and
• a processing device coupled to said detector array and configured to:
• instruct said detector array to acquire tomographic image data of the object at a plurality of frequencies;
• generate a composite image of the object at each of the plurality of frequencies using the acquired tomographic image data;
• determine a scaling factor for a first material at each of the plurality of frequencies;
• determine a scaling factor for a second material at each of the plurality of frequencies;
• and
• decompose the composite images into a first discrete image and a second discrete image using the determined scaling factors, wherein the first discrete image contains any region of the object composed of the first material and the second discrete image contains any region of the object composed of the second material.
