produces uniform radiographic exposure over body tissues of varying thicknesses
what happens to receptor exposure as scatter decreases?
the material filters are made of
factors that affect the thickness of the HVL
types of beam restrictors
the required micrometers of filtration for mammography tubes
inherent filtration
this is how beam restrictors protect the patient
how many HVLs would be necessary to reduce the intensity of the beam to less than 10% of its original value?
with the use of beam restriction, _______ photons exit the tube port window.
to decrease in intensity
purpose of calipers
categories of filtration
what happens to the primary beam when using a filter?
when using a wedge filter, patient exposure will be _______ at the thinnest part of the filter
the primary purpose of beam restriction
what happens to contrast as scatter decreases?
fluoroscopy and mobile equipment are recommended to have this much Al equivalent filtration.
