Abstract:

The objective of this document was to develop a source of pulsed, tunable, monochromatic x-rays using an RF accelerator and terawatt laser for use in medical imaging and treatment. The prototype development is essentially complete and the accelerator and laser are under construction. Delivery of both systems is scheduled for August 2000. System commissioning is scheduled for September 2000. Applications research has produced three-dimensional CT images of animals at resolutions between 35 and 50 microns using monochromatized fan beam geometries. Currently under investigation is comparison of standard mammography with high resolution, two and three-dimension monochromatic plain film and phase contrast imaging.
