Beliefs and behaviors of radiographers concerning “Digital Chest Radiography”
Aims Chest radiography is the first choice for the investigation of cardiovascular and respiratory disease. Radiographer technologists are responsible for managing the radiation exposure to patients and providing adequate image quality according to the ALARA concept. The knowledge and experience of radiographers in performing chest radiography helps to improve the diagnosis of diseases. The aim...
متن کاملQuality comparison of direct digital panoramic radiography and computed radiography panoramic
BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
متن کاملOptimization of Dose and Image Quality in Full-fiand Computed Radiography Systems for Common Digital Radiographic Examinations
IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...
متن کاملComparison of storage phosphor computed radiography with conventional film-screen radiography in the recognition of pneumoconiosis.
Traditional film-screen radiography (FSR) has been useful in the recognition and evaluation of interstitial lung diseases, but is becoming increasingly obsolete. To evaluate the applicability of storage phosphor digital computed radiography (CR) images in the recognition of small lung opacities, we compared image quality and the profusion of small opacities between FSR and CR radiographs. We sc...
متن کاملGeneral Screen Film Radiography and Its Limitations
X-rays are electromagnetic (EM) radiation with characteristics of short wavelengths, very high frequencies and very high energy. High energy EM radiation exhibits characteristics of both waves and discrete bundles of energy called photons. X-ray photon energy is usually measured in kilo-electron volts (keV) and diagnostic x-ray energies are typically 10 to 150 keV. Such high energy EM radiation...
