A Radiographer should use a grid when the part thickness is above ________  and the technical factors used is above ______.

As a radiographer, you are using a DR system that displays EI#’s as part of the DICOM header. The EI#s are calculated as directly proportional and linear to exposure. The image you have created shows marginal quantum noise and an EI# of 1400. The exposure technique you used was 85 kVp@ 15 mAs. To improve image quality and eliminate the objectionable noise, your next step should be to

DR detector element saturation can result in __________.

A satisfactory radiograph is produced using 8 mAs at 85 kVp without a grid. A second film is requested using an 8:1 grid. What mAs is needed to produce the second radiograph?

In which of the following systems does the radiographer select the anatomic part from the console menu?

A Potter-Bucky diaphragm must move the grid in a direction that is ____ to the direction of the grid lines.

What rule is used in fixed exposure technique systems?

Examples of artifacts that must be accepted include all of the following except1. pacemakers.2. dental bridges.3. pleural drainage tubes secured with safety pins.4. endotracheal tubes.5. heart monitoring lines.

Given the image of a box on an incline shown in Question 21, If the static friction coefficient between the box and the slope is 0.5, what magnitude of horizontal force is required to push the box up the slope?  Provide your answer in kN, but do not include units in your submittal.

Given the image of a box on an incline shown in Question 21, If the static friction coefficient between the box and the slope is 0.2, what magnitude of horizontal force is required to prevent the box from sliding down the slope?  Provide your answer in kN, but do not include units in your submittal.
