The reduction methods of operator's radiation dose for portable dental X-ray machines
OBJECTIVES This study was aimed to investigate the methods to reduce operator's radiation dose when taking intraoral radiographs with portable dental X-ray machines. MATERIALS AND METHODS Two kinds of portable dental X-ray machines (DX3000, Dexcowin and Rextar, Posdion) were used. Operator's radiation dose was measured with an 1,800 cc ionization chamber (RadCal Corp.) at the hand level of X-...
متن کاملEffect of the amount of battery charge on tube voltage in different hand-held dental x-ray systems
PURPOSE Hand-held dental x-ray system is a self contained x-ray machine designed to perform intraoral radiography with one or two hands. The issue about its usage as general dental radiography is still in dispute. The aim of the present study was to assess the relationship between the amount of battery charge and the tube voltage in different hand-held dental x-ray systems. MATERIALS AND METH...
متن کاملSensor Selection for Hand-Held Portable Gas Detectors
Hand-held portable gas detectors often may be configured to have 4, 5, or even 6 different sensors installed by the factory. The sensor selection should be made by the prospective purchaser based on the intended application of the instrument after they take possession of the device. The prospective user needs to convey to the factory such possible applications as Confined Space Entry, HazMat Re...
متن کاملImage Quality and Radiation Dose for Intraoral Radiography: Hand-Held (Nomad), Battery Powered vs. Wall-Mount X-Ray Systems
A hand-held, battery-powered dental intraoral x-ray system (60 kV, constant potential output) was compared to a conventional, wall-mounted intraoral x-ray system (70 kVp, self-rectified output) in terms of image quality, and patient and staff radiation doses. The image quality comparison included quantitative measurements of image sharpness (resolution) and contrast. Patient doses were compared...
متن کاملThe dose received by patients during dental X-ray examination and the technical condition of radiological equipment.
BACKGROUND Implementation of X-ray dental examination is associated with the patients exposure to ionizing radation. The size of the exposure depends on the type of medical procedure, the technical condition of the X-ray unit and selected exposure conditions. The aim of this study was to determine the dose received by patients during dental X-ray examination and the assessment of the technical ...
