Which of the following is NOT a component of image enhancement?

Identify each of the following statements as a myth or a fact in regards to digital imaging.  Responses may be used more than once.

The following chest x-ray was taken on a patient in the emergency department. How will the positioning and collimation of the part affect the histogram analysis? chest x-ray 4.jpg

A satisfactory PA chest x-ray is performed on a patient using manual technical factors of 100 kVp and 8 mAs on a patient that is 28 cm in thickness.  The next patient scheduled for a PA chest x-ray measures 24 cm.  Which of the following sets of technical factors would be optimal in maintaining density and keeping patient exposure to a minimum?

The postprocessing feature demonstrated by the red arrows in the following radiograph is called: electronic masking.jpg

Image process algorithms are used to:

The area between S1 and S2 on a histogram represents the:

Refer to the following illustration of a technologist performing a PA chest x-ray using AEC on a CR system. If the positioning remains unchanged and the two outer detectors are selected for this exposure, how will this affect the resulting radiograph? AEC detector chest 2.jpg

A radiographic exposure is made of a lateral lumbosacral spine projection on an obese patient using 78 kVp and 300 mAs and demonstrates adequate density.  Which of the following technical factors will demonstrate maintain density and decrease patient exposure?
