Intraoral receptor
consists of a tubehead, extension arm, and control panel
what is a nomad?
a portable type of intraoral dental x-ray machine that allows for exposures outside of the dental office, is battery powered, produces high-quality diagnostic images, and is approved in many states.
Extraoral PAN machine
A type of dental x-ray machine that contains components such as the x-ray tubehead, head positioner, and exposure controls.
Performance Standards
Regulations set after 1974 by the federal government for the manufacture and installation of dental x-ray equipment
with usage dictated by state and local governments.
required to be registered with the department of community health, healthcare facility regulation, for safety purposes
Intraoral Machine
Components include the tubehead containing the x-ray tube, extension arm for positioning, and control panel with on-off switch, exposure button, and control devices.
Beam alignment device
An instrument aiding in positioning the PID relative to the tooth and receptor
XCP
helps avoid cone-cutting and capture desired structures.
Collimating Device
Used with a beam alignment device to restrict the size of the x-ray beam and limit radiation exposure.
Types of Receptor Holders
disposable Styrofoam bite-blocks, molded-plastic devices like Snap-A-Ray, EndoRay, Uni-bite, and Rinn XCP and BAI Instruments.
Digital Imaging
Utilized in dentistry for diagnosis, treatment planning, and monitoring of oral health, offering advantages like immediate viewing, manipulation, storage, and sharing.
Examples of what digital imaging is need to view
cavities, impacted teeth, bone loss, infections
components of digital imaging fundamentals
proper pt positioning, aiming the image device accurately, ensuring image quality and clarity
Analog Image
Historically used in dental imaging, primarily involving conventional X-ray film.
sensor
digital technology used in modern dentistry to capture images
digitalized
the process of converting an image into a digital form
digital image advantages
immediate viewing, manipulation (adjusting contrast and brightness), easy storage and retrieval, ability to share electronically with other HCPs
Direct Imaging
involves capturing X-ray images onto a digital sensor that is placed in the pt's mouth
Indirect Digital
x-ray images are captured with a traditional machine and film and then converted into a digital format.
Film Composition
Includes film base, adhesive layer, film emulsion, and protective layer in dental x-ray film.
Latent Image Formation
x-rays ionize silver halide crystals, with the thickness of objects determining contrast and the image can't be seen until the film is processed
Intraoral Film Packaging
Consists of x-ray film, paper film wrapper, lead foil sheet, and outer package wrapping.
Intraoral Film Size
Includes periapical, bitewing, and occlusal
Extraoral Film
composed of film types, film packaging, extraoral equipment
extraoral film types
screen film
nonscreen film
extraoral film packaging
no packet
boxed in packages of 50-100
extraoral equipment
intensifying screens
cassettes
Film Processing
A series of steps converting latent images into permanent visible ones; involving development, rinsing, fixing, washing, and drying.
development
hydroquinone and elon
softens the film emulsion
rinsing
stops the development process
removes developer from the film
fixing
removes unexposed silver halide crystals
washing
removes all excess chemicals from the emulsion
drying
films must be dried before they can be handled
Automatic Processor
A device used in film processing to automate the steps of developing, rinsing, fixing, washing, and drying dental radiographs.
Film Mounting
Essential for dental professionals, involves arranging radiographs in anatomic order, can be viewed more efficiently and are easier to interpret
what materials can film mounts be made of?
cardboard, plastic, vinyl
Film mount
Supports and arranges dental images in anatomic order, available in various sizes and configurations, and may be opaque or clear to mask surrounding light.
