Communication & Immobilization
An interaction that produces a satisfying result through an exchange of information
Effective Communication
Sensing devices most often used to determine skin dose directly
Thermoluminescent Dosimeters (TLD)
Blotchy radiographic image that results when an insufficient amount of x-ray photons reach the IR
Quantum mottle/noise
Refers to the radiation absorbed by the epidermis
Skin Dose
According to the U.S Public Health Service, the approximate genetically significant dose for the U.S population is this value
0.20 mSv
Nonverbal messages that, if understood as intended will promote effective communication
Body Language
These types of radiologic examinations should not be performed at all
Nonessential Examinations
Standardization in the processing of digital images. Includes regular monitoring and maintenance of all processing and image display equipment in a facility
Quality Control Program
Represents the dose that, if received by everyone, would equal the total genetic effect of only those actually exposed
Genetically Significant Dose
Tech Factor for Chest X-ray
110-125kVp, 2-3mAs
Types of patient motion (Give an example for each)
Voluntary and Involuntary
System with the highest radiation sensitivity
Hematopoietic
When digital images are acquired, this process is essential to produce a high-quality diagnostic image
Postprocessing
Gently is radiation safety for pediatric patients
Wisely is radiation safety for adult patients
Fluoroscopically Guided Positioning
Shorten exposure time, increase mA
10 days of natural background radiation
An alternative procedure used in place of the radiographic grid for reducing scattered radiation
Air Gap Technique
Well-managed imaging departments use these for each X-ray unit to ensure uniform selection of exposure factors when a properly calibrated AEC is not employed

What does DEXA stand for?
Dual Energy X-ray Absorptiometry
