Answer to Question 1

full wave rectification

Rationale: Full wave rectification is used most often because it is most efficient. There are 4 diodes used so that both positive and negative portions of the pulse create a constant flow of positive energy.

Answer to Question 2

restricting the field size

Rationale: Beam restriction is the single most important factor to minimize patient dose. Beam restriction with intent to restrict the field size will reduce the production of scatter. Decreasing the part thickness, such as use of a compression band, will decrease scatter production
