Abstract

The feasibility of using a flat panel based cone-beam computer tomography (CT) system for 3-D breast imaging with computer simulation and imaging experiments was analyzed. The 3-D phantoms were analytically modeled to simulate a breast loosely compressed into cylindrical shape with embedded soft tissue masses and calcification. It was found that 355-425 μm calcifications were visible in images obtained at 77 kVp with a voxel size of 316 μm and a center dose of 600 mrads. The results show that 300-315 μm calcifications are visible in images obtained at 60 kVp with a voxel size of 158 μm and a center dose of 3.6 rads.
