Where is scatter produced?
in the patient
What are the three principle factors that affect scatter production?
Patient thickness, KV, and collimation/beam restriction
What happens to the production of scatter when you increase KVP?
Scatter increases
Describe the contrast if you increase kVp, use both terms
lower contrast or long scale
What happens to the production of scatter if you increase part thickness?
Scatter increases
What happens to the production of scatter if you increase collimation
Scatter decreases
Name the three types of beam restrictors?
Aperture diaphragms, cones/cylinders, collimation
What does PBL stand for?
Positive beam limitation
What is off-focus radiation
x-rays produced, but not at the focal spot it adds to the image blur
What does beam restriction mean
collimation
