In general when regarding linear attenuation coefficient: When photon energy increases what happens to the attenuation coefficient> 

The purpose of collimation in computed tomography is:I. to protect the patientII. to ensure a constant beam width at the detectorIII. to reduce scatter radiation

The radiation beam from an x-ray tube is:

Which of the following refers to the ability of the computed tomography detector to capture, absorb, and convert x-ray photons into electrical energy?

The purpose of the imaging system is to:I. produce x raysII. shape and filter the x rayIII. detect and measure the radiation passing through the cross-section

Interpolation methods that result in a scan wider than what was selected is known as what

Image reconstruction that uses raw data to automatically produce images during patient scanning is called:
