TīmeklisThoracic Radiographic Exposure. From a technical standpoint, thoracic radiographic exposure should be obtained using a high peak kilovoltage (kVp) (80-120 kVp) and low milliampere-second (mAs) (1-5 mAs) technique. This technique allows for latitude (long gray scale) images, which are important when evaluating the structures of the thorax.
