Robust Control of a Hard Disk Driveecially-designed CCDs (charge coupled devices) with a 25-µm pixel pitch. The detector element fill factor approaches 100%. We have produced and are testing CCD structures that utilize both surface and buried channel structures. We are developing selenium blocking layers that are optimized for electron signal transfer to a CCD.

Digital mammographic application of a single photon counting pixel detectorer. We have tested the image quality and the stability of our acquisition system imaging some phantoms used for mammografic quality checks. Our system allows to see low contrast details with a patient dose comparable with that given in mammographic examinations.

Characterization of an FFDM unit based on a-Se direct conversion detectorcomplete characterization of such system: detector response, MTF, NPS and DQE calculation will be presented. MTF and DQE at Nyquist frequency (5.88 lp/mm) are equal to 38% and 15%, respectively. The detector linearity is very good under the typical mammographie tested exposure conditions.

Breast Cancer Screening using a Dedicated Breast CT Scanner: A Feasibility Studyn Rose’s criterion (SNR≥5), that breast CT can produce excellent image quality at mean glandular doses comparable to mammography. The potential to identify smaller lesions may improve early detection performance, which in turn would likely result in a reduction of breast cancer mortality.

Full Field Digital Mammography with a CCD Based Slot-Scanned Detector. Physical Characteristics Mease) at different detector exposures. Result shows that while the MTF for scan and subscan directions are quite similar, differences between colums (scan direction) and rows (subscan direction) appear for NPS and NEQ.
