Interactions
Contrast
Density
Random
100
The positive side of the Xray tube is called this?
What is Anode
100
This interactions is good for the patients?
What is Comptons
100
What is the main controller of contrast? Is contrast the Quality or the Quantity?
What is KVP, Quality
100
What is the main contoller of Density?
What is MAS
100
Name three things that negativly effect the X-ray
What is OID, SID, Geometry, To light or dark, Motion
200
The Filliment is on this side of the X-ray tube?
What is the Cathode
200
This interaction is characterized as a sudden brakeing around the nucleus? Where is this done?
What is Brems and the Tube
200
When adjusting contrast by using KVP what "rule" do we follow? What will this do to the Density?
What is 15 percent rule and double it.
200
When changing Density what percent do you want to go up or down to make a noticable change on the X-ray film? As a good rule how much do normally adjust the MAS?
What is 30 percent and 50 percent
200
Incresing the OID will do what to the X-ray image and what can we do to compinsate for this? And when we compinsate for OID we also have to adjust the what?
What is magnifiy the image and increase the SID and adjust the MAS and or KVP
300
The target is located on this side of the tube and has an angle of how many degrees?
What is Anode and 12 degrees
300
The interaction happens when the "k" shell is knocked from the nucleus? How many KeV's does this take?
What is characteristic and 69.5 KeV
300
DOUBLE JEOPARDY!!!! High KVP will cause this type of contrast? (you must name both names) and will also cause more scatter, what is one this we can do to help reduce the scatter from reaching the IR?
What is Low and Long, use a Grid.
300
What is the definition of Density? In DR the window blank will change the Density on the screen
What is the amount of blackening on a film. Window Level
300
Double Jeopardy!!!! What is the definition of Attenuation? Also X-ray photons can interact with 3 parts of an atom, name them.
What is Attenuation is the reduction in the number of x-ray photons in the beam. Whole atom, electron or the nucleus.
400
the rotor spins at a speed of how many RPM's and is made up of what?
What is 2300 and Tungstun.
400
This interaction happens when the incoming photon caused the electron to "shake" and get "excited"? What energy will this make this happen? (Low or High)
What is classical or coherent. Low energy
400
what is the definition of contrast?
What as the visible differences between any two selected areas of density
400
Doubling the MAS will double the "what" and what law is this considered?
What is Density and reciprocity law
400
What are the 4 things that are needed for X-ray production?
What is seperations of electrons, concentration of electrons, high speed, and sudden braking.
500
When electrons are boiled off the filliment it creates an electric cloud also called this?
What is Thermonic emmision
500
This interaction creates the "whites" on the X-ray? Good or bad for the patient?
What is photoelectric and Bad.
500
In DR radiography adjusting the Window "blank" will change the contrast on the screen?
What is Window Width
500
Density is this percent greater on the cathode side of the tube and what "effect" is this?
What is 45 percent and Anode heel effect
500
High KVP- what are 4 things we can think of when we use High KVP
What is low and long, comptons, bad for pt, scatter,
