The purpose of a grid is to restore __ in the remnant xray beam signal

An 80-kV photon undergoes a coherent scattering interaction with an orbital electron having a binding energy of 8 kV. What is the energy of the resulting scattered photon?

For a particular radiograph, the exposure indicator shows that twice too much exposure was used. If this radiograph was taken using the AEC, what would the "density" control be set to in order to correct the exposure the next time this procedure is done on a similar patient

When changing to a higher speed of image receptor plate, or the ratio of the grid in an x-ray table Bucky is changed to a lower ratio, the thyristor of the AEC must be:
