Exam 15: Additional Equipment

The radiographer should stand at least _________ away from the patient and x-ray tube when making an exposure using mobile radiographic equipment.

A common site for mobile fluoroscopy is:

Breast compression:

Which of the following radiographic units does not need to be plugged into the wall while producing x-rays?

The dedicated unit designed to image the thorax in the upright position is the:

During a DXA scan,the anatomy is scanned twice,each time with:

The primary result of a DXA scan is a detailed radiograph of the hip or lumbar spine.

Unless otherwise required,during C-arm fluoroscopic procedures the x-ray tube should be located:

Bone densitometry uses x-rays to determine the level of bone density because:

The exposure amplitude is always _______________________ the tomographic amplitude.

A dedicated chest room allows the radiographer to stay in the room while the images are being processed.

The radiation dose to the breast ______________________ when magnification techniques are used.

This type of dedicated unit is typically used to image the mandible and teeth.

Unless otherwise required,during C-arm fluoroscopic procedures the image intensifier should be located:

The fixed point that is placed at the level of the anatomic structures to be imaged during tomography is the:

The kVp is very low because of the breast's:

The goal of linear tomography is to:

Linear tomography is used to overcome the limitation that some anatomic areas are difficult to see because they are superimposed by other structures.

As compared with standard radiography,patient exposure during tomographic procedures is:

There are generally _____ sets of locks on mobile C-arm fluoroscopic equipment.
