Exposure/dose
5000 mrem or 5 rem
What is the annual effective dose limit for an occupational worker?
Wide latitude for errors when being used
Controls the quality and the quantity of the x-ray beam.
What is kVp?
The remanence of a previous high exposure that can be found on a CR that wasn't completely erased.
What is ghosting?
A means of providing more information on the image with words such as technique or time.
What is digital annotation?
500 mrem or .5 rem
What is the educational or public exposure annual dose limit?
The combination of inherent and added
What is total filtration?
Numbers created by the manufacturer that represent exposure and can help evaluate proper exposure.
What are EI?
Anything that doesn't add to the diagnosis of a patient on an x-ray. Can be electronical or on the patient.
What is an artifact?
The girls' gun that Dwight Schrutte wore to impress.
What is the Bomont Adams?
Distance, time, and shielding
What are the principles/foundational concepts of personal exposure reduction?
Filtration that isn't in control of the technologist and prevents the release of secondary radiation within the tube.
What is inherent filtration?
What is an OID increase?
Uses a Thin film transistor and a photoconductor with selenium to convert incoming x-ray photons into a visible image.
What is direct conversion digital radiography?
What is a focused grid?
Ionization chamber
What is a means for detecting radiation dose that uses a gas that is ionized and then gauged for exposure that can give immediate read outs? Also found in the AEC which I will learn more about next quarter.
Viewed as grainy or underpenetrated areas on the film and the result of misaligning the tube to the IR.
What is grid cutoff?
A decrease in kVp of 15%, a longer wavelength, and less beam intensity.
What are decreases in image receptor exposure?
The sensing area compared to the non-sensing area on the DR that is directly related to the spatial resolution. The higher the number the better.
What is the fill factor?
The celebrity name of the top two rated films at the box office right now.
What is Barbenheimer?
Worn at the level of the collar
What is a personal monitoring device? Dosimeter?
The ability to clean up scatter that is the product of the height of the lead strips and the space between them.
What is grid ratio?
Primary controller of the image receptor exposure.
What is milliamperes?
What is the LUT?
The unsharpness of the edges of the anatomy in the radiographic image.
What is penumbra?
