To address infection control when doing digital imaging, you must make sure to cover the sensor or PSP with a sleeve. This is especially important because you cannot disinfect the sensors or PSP.
both statements are true
first is true and second is false
first is false and second is true
both statements are false.
What are the two phases that CBCT is comprised of?
data distribution
data acquisition
data reconstruction
data configuration
The first phase of CBCT involves an x-ray unit connected to an x-ray detector that circles the had of a patient producing 2D images. The second phase involves reconstructing those images into 3D information.

50-60
60-70
70-80
80-90
At what point do you need to put your mask on while exposing digital images?
you don't need one
you only need one when you are cleaning the room
immediately prior to processing
after washing your hands, before putting your gloves on.
What types of image receptors are used in digital radiography?
A) charged-coupled device (CCD) sensor

Comparing PSP images to sensor images, the PSP images are lower resolution/quality when looking at line pairs per millimeter (lp/mm). PSPs can produce 15-20 lp/mm where sensors can produce 24 lp/mm at the maximum resolution settings.
