Assume that 200 mA at 0.5 seconds was used to produce a radiograph. Because of patient motion, you want to decrease the exposure time to 0.25 seconds.  What new mA must be used to maintain the same radiographic exposure?

In imaging the breast in the MLO projection, compression to the lower portion of the breast is compromised if: 1. the image receptor is at the correct level2. the patient has a protruding abdomen3. too much axilla and shoulder are under the compression

In the lateral projection of the scapula, the vertebral and axillary borders are superimposed acromion and coracoid processes are superimposed inferior angle is superimposed on the ribs

For mobile equipment, the source to skin distance shall not be less than

If the filtration of a radiographic unit is inadvertently omitted for a series of abdominal exposures, the greatest increase in exposure would occur to the

If the grid ratio was increased and no technical compensations were made, the resulting deviation index would:
