Liver motion during cone beam computed tomography guided stereotactic body radiation therapy.
PURPOSE Understanding motion characteristics of liver such as, interfractional and intrafractional motion variability, difference in motion within different locations in the organ, and their complex relationship with the breathing cycles are particularly important for image-guided liver SBRT. The purpose of this study was to investigate such motion characteristics based on fiducial markers trac...
متن کاملPediatric Phantom Dosimetry of Kodak 9000 Cone-beam Computed Tomography.
PURPOSE The purpose of the study was to evaluate the radiation dose of the Kodak 9000 cone-beam computed tomography (CBCT) device for different anatomical areas using a pediatric phantom. METHODS Absorbed doses resulting from maxillary and mandibular region three by five cm CBCT volumes of an anthropomorphic 10-year-old child phantom were acquired using optical stimulated dosimetry. Equivalen...
متن کاملKnowledge of Iranian dentists about cone beam computed tomography. A questionnaire study
Introduction: Cone beam computed tomography (CBCT), is a relatively new imaging technique in dental and maxillofacial fields, with versatile abilities and applications. If the advantage of CBCT is well understood and established; the technique will be properly applied in dental planning and treatment along with tremendous benefits to the patients. This study was designed to evaluate the knowled...
متن کاملA Phantom Study on Target Localization Accuracy Using Cone-Beam Computed Tomography
The purpose of this study is to evaluate the 3-dimensional target localization accuracy of cone-beam computed tomography (CBCT) using an on-board imager (OBI). An anthropomorphic pelvis phantom was used to simulate a range of offsets in the three translational directions and rotations around each of the three axes. After a translational or rotational offset was applied, a CBCT scan of the phant...
متن کاملComparison of transportation and centering ability using RECIPROC and iRace: A cone-beam computed tomography study
BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...
