title = "Search for optimal tube voltage for image plate radiography",
abstract = "Purpose: To search for the tube voltage which results in the highest clinical image quality per effective dose unit for chest and pelvis radiography respectively, using image plates. Methods: Two anthropomorphic phantoms were imaged with several different tube voltages. For the chest phantom, the tube voltage was varied between 70 and 150 kV, and for the pelvis phantom between 50 and 102 kV. The mAs settings were chosen so that the effective dose to the phantom was the same, regardless of the tube voltage, for the two examinations respectively. The clinical image quality of the resulting images was evaluated by a panel of experienced radiologists with visual grading analysis of defined anatomical structures taken from the European Image Criteria. Images produced with the standard tube voltage settings (125 kV for chest and 70 kV for pelvis) were used as reference. These two kV settings were previously used for screen film radiography. Results: For both the chest and the pelvis examinations the image quality at a constant level of effective dose increased when the tube voltage was reduced. Conclusions: The image quality of image plate radiography can be increased by lowering the tube voltage compared to what was used for screen film radiography.",
