Storage Phosphor Digital Radiography in Portable Chest Imaging: Comparison of Image Quality with Conventional Film-Screen System with Variation of mAs

ABSTRACT

PURPOSE: To compare image quality of storage phosphor digital radiography(DR) with film-screen radiography in portable chest imaging, and to assess the minimum X-ray dose that can be applied to DR in adults without image degradation, and also to compare image qualities of low dose and standard dose DR. Materials and Methalos A geometrical phantom similar to the human thorax was imaged by a portable radiographic unit with fixed kVp and variable m
