摘要: Abstract Purpose To investigate the dose saving potential of direct-converting CdTe photon-counting detector technology for dedicated breast CT. Materials and methods We analyzed modulation transfer function (MTF), noise power spectrum (NPS) detective quantum efficiency (DQE) two technologies, suitable CT (BCT): a flat-panel energy-integrating with 70 μm 208 μm thick gadolinium oxysulfide (GOS) 150 μm cesium iodide (CsI) scintillator 1000 μm sensor. Results The measurements GOS thicknesses delivered 10% pre-sampled MTF values 6.6 mm−1 3.2 mm−1, DQE(0) 23% 61%. value CsI 6.9 mm−1, was 49%. sensor reached 8.5 mm−1 85%. Conclusion allows significant reduction compared to scintillation used in BCT today. Our comparative evaluation indicates that high may be possible by using detectors, without loss spatial resolution.
