Paper Abstract

Ionizing radiation from medical imaging now accounts for over 95% of all man-made radiation exposures and is the single largest radiation source after natural background radiation. As a result, new techniques are under development for reducing radiation exposure incurred in diagnostic radiography. It was the purpose of this study to determine if a transmission X-ray tube and generator system in conjunction with a flat-panel detector is capable of achieving diagnostic quality radiographic images at reduced radiation doses. It was found that transmission tube technology, in combination with a flat-detector system, is capable of producing radiographic images of sufficient quality for diagnostic medical imaging within certain parameters. It is postulated at this time that when low mAs is required, as in imaging of neonatal and young pediatric patients, the transmission tube may prove to be very effective in obtaining diagnostic images at reduced radiation dose.
