CT Imaging Collimation

To scatter radiation throughout the patient

To make the imaging process faster

To restrict the beam to the anatomy of interest and reduce patient radiation dose (correct)

To increase patient radiation dose

To widen the beam for better imaging

To increase scattered radiation

To reduce beam width at the detector

To shape the beam and remove scattered radiation (correct)

They are used to increase slice thickness

They help restrict the beam and maintain a constant beam width at the detector (correct)

They are used to increase patient radiation exposure

They ensure a variable beam width at the detector
