Cone beam CT for dental and maxillofacial imaging: dose matters.
The widespread use of cone-beam CT (CBCT) in dentistry has led to increasing concern regarding justification and optimisation of CBCT exposures. When used as a substitute to multidetector CT (MDCT), CBCT can lead to significant dose reduction; however, low-dose protocols of current-generation MDCTs show that there is an overlap between CBCT and MDCT doses. More importantly, although the 3D info...
متن کاملEvaluation of Factors Affecting Absorbed Dose, Optimization Methods and Patient Dose Reduction in Dental Cone Beam CT (CBCT)
Introduction: Nowadays the use of cone beam computed tomography in dental imaging is increasing, although this method has a much lower dose than conventional CT scans, it delivers a higher dose than the panoramic and periapical patients therefore, , the aim of this study was to investigate the factors affecting the patients' dose in dental CBCTs and methods of optimizing and reducing the patien...
متن کاملUsing GafChromic film to estimate the effective dose from dental cone beam CT and panoramic radiography.
OBJECTIVES To demonstrate the feasibility of GafChromic(®) XR-QA2 (ISP Corp., Wayne, NJ) as a dosemeter when performing measurements of the effective dose from three cone beam CT (CBCT) units and to compare the doses from examinations of three common dental clinical situations. A second aim was to compare the radiation doses for three digital panoramic units with the doses for the CBCT units. ...
متن کاملEffective dose from cone beam CT examinations in dentistry.
Cone beam CT (CBCT) is becoming an increasingly utilized imaging modality for dental examinations in the UK. Previous studies have presented little information on patient dose for the range of fields of view (FOVs) that can be utilized. The purpose of the study was therefore to calculate the effective dose delivered to the patient during a selection of CBCT examinations performed in dentistry. ...
متن کاملSU-E-I-06: Measurement of Skin Dose from Dental Cone-Beam CT Scans.
PURPOSE To directly measure skin dose using point-dosimeters from dental cone-beam CT (CBCT) scans. To compare the results among three different dental CBCT scanners and compare the CBCT results with those from a conventional panoramic and cephalomic dental imaging system. METHODS A head anthropomorphic phantom was used with nanoDOT dosimeters attached to specified anatomic landmarks of selec...
