Answer to Question 1

wedge filter

Rationale: A wedge filter will not serve as a means of beam restriction, but rather a means to create a more uniform density on parts of uneven part thickness, e.g., foot, t-spine.

Answer to Question 2

increased SID

Rationale: A grid is suggested with parts measuring over 10 cm and with higher kVp. Increased kVp values influence the amount of scatter radiation produced. In cases where increased OID is a factor with a thicker part, the theory of the air-gap technique could apply, avoiding the need for a grid.
