Absorbed doses for patients undergoing panoramic radiography, cephalometric radiography and CBCT.
OBJECTIVES Contemporary dental radiology offers a wide spectrum of imaging methods but it also contributes to an increase in the participation of dental radiological diagnosis in the patient's exposure to ionizing radiation. The aim of this study is to determine the absorbed doses of the brain, spinal column, thyroid and eye lens for patients during panoramic radiography, cephalometric radiogra...
متن کاملparotid-absorbed doses: a comparison between spiral tomography and panoramic
conclusions there was no statistically significant difference in the parotid absorbed dose between spiral tomography and a panoramic radiograph (p value = 0.18). the overall results of this study were similar to other studies. results for the tube side parotid, the average absorbed doses in spiral tomography of the anterior and posterior parts of the maxilla and mandible, with the 2 mm slice th...
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 کاملDiagnostic Reference Level Arising from Dental Panoramic Radiography
Introduction The present work describes a study in which, based on patient dose measurements, thermoluminescent dosimeters were used to obtain the diagnostic reference level arising from panoramic radiography. Materials and Methods Ten panoramic units and a sample of 15 patients per X-ray unit were studied. Two thermoluminescent dosimeter chips were placed on the skin surface of selected organs...
متن کاملcomparison between absorbed doses in target organs in panoramic radiography, using single emulsion and double emulsion films
the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...
