Abstract
The FDA has approved the SenoScan slot-scanning Full-field Digital Mammography system. A high power Tungsten-target x- ray tube enables breast imaging with 0.22 s effective exposure time. A 21-cm X 29-cm area is scanned in less than 6 seconds, at a typical clinical technique of 30 kVp, 170 mA. The detector comprises a Thalium-doped Cesium Iodide scintillator coupled to a combination of four CCDs abutted along their narrow dimension to from a 10-mm by 210-mm slot. With the CCDs operated in time-delay-and-integration mode along the narrow dimension, the system functions in a continuous scanning mode. The MTF in the standard and high- resolution modes extend to 10-cycles/mm and beyond 14 cycles/mm respectively. The Detective Quantum Efficiency curve starts at 50 percent at DC and extends to 10 cycles/mm in Standard model. Accordingly the SenoScan system enables screening and diagnostic breast imaging with a limiting resolution approaching that of film-based systems. The overall system design and intrinsic scatter rejection efficiency directly translate in high DQE characteristics that enable screening at a significantly reduced patient dose.
