Grids are necessary to apply to imaging when:
A part measures over 3 cm
A part measures over 10 mm
Greater than 70 kVp is applied
Less than 70 kVp is applied
Greater than 70 kVp is applied
Rationale: A grid is positioned between the part of the patient and the image receptor in efforts to clean up scattered or divergent rays that may be more detrimental to image quality. Grids are advantageous to image quality when part thickness exceeds 10 cm and kVp values are greater than 70.
