prefix - Answers comes before the root to modify the meaning
root - Answers foundation of the word; it's basic meaning
suffix - Answers comes after the root to modify the meaning
what does the term "anti" represent in the word antisepsis? - Answers prefix
what does the term "sepsis" represent in the word antisepsis? - Answers root
which of the following is the correct sequence in which a medical term is usually defined? -
Answers suffix, prefix, root
what is a combining vowel? - Answers vowel included at the end of the root
what is a combining form? - Answers refers to the root plus the combining vowel
when do you drop a combining vowel? - Answers when the suffix begins with a vowel
when do you keep a combining vowel? - Answers when the suffix begins with a consonant
what is an acronym? - Answers a new word is formed by taking the first letter of other words,
such as GERD
what is meant by the term "exposure"? - Answers the amount of radiation received by the image
receptor
what is your imaging goal? - Answers to get the best image quality with the least amount of
radiation
if you increase mA, will exposure increase or decrease? - Answers increase
if you increase time, will exposure increase or decrease? - Answers increase
if you increase kV(penetration) , will exposure increase or decrease? - Answers increase
if you increase SID (image receptor to the x-ray tube), will exposure increase or decrease? -
Answers decrease
what is the appropriate exposure to the patient evaluated by in digital imaging? - Answers
exposure indicators
what is the ideal exposure in mAs? - Answers 30 mAs
what is the range for Deviation index? - Answers -3 through +3
what does the term "brightness" pertain to when it comes to radiologic imaging? - Answers how
, dark/light the image is on a monitor
true or false : brightness is maintained by the computer software so that the image is never too
dark or too light - Answers true
is brightness related to exposure to the IR? - Answers no
what is radiologic contrast? - Answers differences between two adjacent radiographic shades
of gray
what is high contrast? - Answers larger differences (black & white)
what is low contrast? - Answers smaller differences (many similar shades of gray)
when looking at contrast in a radiologic image, what do you aim for? - Answers lots of shades of
gray in-between the image
what plays the biggest role in contrast? - Answers kilovoltage (kV)
how does low kilovoltage affect contrast? - Answers the contrast will be higher
how does high kilovoltage affect contrast? - Answers the contrast will be lower
when you have high kV, do you want to have a high or low mAs to maintain the balance? -
Answers lower mAs
when you have a low kV, do you want to have a high or low mAs to maintain the balance? -
Answers higher mAs
scatter radiation adds an extra layer of gray over recorded image, would this higher or lower the
contrast? - Answers lower the contrast
what is a radiographic grid? - Answers device placed between the patient and the IR to absorb
scatter radiation
will use of a radiographic grid make the contrast higher or lower? - Answers higher
where is the radiographic grid located in the imaging system? - Answers above the image
receptor in the buckey tray
What is a collimator? - Answers a device (light box) that has a light to center lead shutters to
restrict the size of the beam
Where is scatter radiation produced? - Answers the patient
if you have a smaller exposure field, will contrast be higher or lower? - Answers contrast will be
higher
