Radiation Ch 1
Question | Answer |
---|---|
Bisecting Technique | An exposure technique in which the central beam of radiation is directed perpendicular to an imaginary line that bisects the angle formed by the recording plane of the image receptor and the long axes of the teeth. |
Cone | Older term used to describe the position indication device or beam indicating device. |
Computed Tomography (CT) | Radiographic imaging technique that images a solid slice of tissue while blurring out other structures. |
Cone Beam Computed Tomography(CBCT)& Cone Beam Volumetric Imaging (CBVI) | CT scanning that is designed specifically for maxillofacial use. |
Digital Imaging | A method of producing a filmless radiographic image using a sensor and trasmitting the electronic info directly into a computer which serves to acquire, process, store, retrieve, and display the radiographic image. |
Dosage | The radiation absorbed in a specified ares of the body measured in grays or rads. |
Sensor | For use in digital imaging. an electric or specially coated plate that is sensitive to x-rays. Placed intraorally to capture a radiographic image when xposed to x-rays. |
Oral Radiology | Procedures that pertain to producing radiographs of the teeth and/or the oral cavity. |
Panoramic Radiography | Procedure performed with a special purpose x-ray that uses a stationary patient and a simultaneously moving x-ray source and image receptor to produce an image of the entire dentition and surrounding structures. |
Paralleling Technique | Intraoral technique that places the image receptor positioned parallel to the long axes of the teeth while the central beam of radiation is directed perpendicularly toward both the teeth and the image receptor. |
Position Indicating Device (PID) | Also called Beam Indicating Device (BID). An open ended, cylindrical or rectangular device attached to the tube head at the aperture to direct the useful beam of radiation. |
Radiograph | An image produced on photo sensitive film by exposure to rays. |
Radiography | The making of radiographs by exposing and processing x-ray film. |
Roentgen Ray | The first name given to the x-ray. Named after Wilhem C. Roentgen. |
Roentgenograph | The first name given to radiographs. Named after Wilhelm C. Roentgen. |
Tomography | A radiographic technique used to show detailed images of structures located within a predetermined plane of tissues while eliminating or blurring those structures in the planes not selected. |
X-Ray | Radiant energy of short wavelength that has the power to penetrate substances and to record shadow images on photographic film phosphates and digital sensors. |
X-Ray Film | Intraoral film packaged in a moisture proof outer plastic or paper wrap. |
