A dual-energy subtraction technique for microcalcification imaging in digital mammography—A signal-to-noise analysis

Breast cancer may manifest as microcalcifications (μCs) in x-ray mammography. However, the detection and visualization of μCs are often obscured by the overlapping tissue structures. The dual-energy subtraction imaging technique offers an alternative approach for imaging and visualizing μCs. With th...
