In general, flat panel fluoroscopy designs use less radiation than image intensifiers. 

Which of the following is a variable transformer that is used to select the kVp for the x-ray circuit?

In direct conversion digital radiography (DR), how are the x-rays processed to display the image?

During mobile exams, it is the radiographer’s responsibility to request that who leaves the area before an exposure is made?

For a PA chest, the anode should be placed towards the diaphram. 

What is the minification gain for an image intensification tube with an input screen diameter of 8 inches and an output screen diameter of 2 inches? 

What is a look-up table (LUT) in digital radiography?

Minification gain is a decrease in brightness or intensity in a fluoroscopy machine.
