Evaluation of silicona microstrip detectors as X-ray sensors in digital mammographyMali, Tadej (Avtor) Cindro, Vladimir (Avtor) Mikuž, Marko (Avtor) Zdešar, Urban (Avtor) Jančar, Breda (Avtor) Background. Position sensitive silicon microstrip detectors are used as sensors for X rays in a digital imaging system. Silicon detectors were used inan edgeon geometry, yielding high X ray detection efficiency. Material and methods. A small detector system was assembled and tested. Images of a standard, 5 cm thick phantom were made and evaluated. It is demonstrated, thatthe use of silicon detectors in mammography could significantly contributeto a reduction of dose. All images were made with skin entrance doses lower than 1 mGy. Results and conclusion. Microcalcifications with a diameter of 350microm could still be detected with skin entrance doses of about 0.25 mGy. It was demonstrated that a 5 Ip/mm pattern can be detected. Image processing should further improve the image quality.Slovenian Medical Association - Slovenian Association of Radiology, Nuclear Medicine Society, Slovenian Society far Radiotherapy and Oncology, and Slovenian Cancer Society 19992024-01-22 14:00:50Neznano17931UDK: 539.1ISSN pri članku: 1318-2099COBISS_ID: 14414887Ljubljanaslby Authors
