Effect Of Field Of Views On Cone Beam Computed Tomography Radiation Dose: Phantom Study, Warangkana Weerawanich, Anchali Krisanachinda

Chulalongkorn Medical Journal

Background : Cone beam computed tomography (CBCT) devices with various types of field of view (FOVs) are currently available in dentistry. Thus, the selection of proper FOVs and number of scans should be considered according to the clinical applications and ALARA principle. Objective : To study the effect of the number of scans and FOVs: one scan of large FOV, one scan of medium FOV and multi-scans of small FOVs, on the radiation dose from CBCT systems using a phantom. Research design : Experimental study (in vitro). Setting : Oral and Maxillofacial Radiology Clinic, Faculty of Dentistry, Mahidol University Methods …
