Exam 8: Image Production

Fluoroscopy produces

Scattered and secondary radiation must be eliminated during radiographic imaging.

The ability to remove electrons from an atom is

Imaging tissues with lower atomic numbers results in

Coherent scattering

At higher kilovoltages within the diagnostic range

All of the radiation that reaches the image receptor is used to create the radiographic image.

A low-kilovoltage x-ray beam results in

Place the following digital imaging steps in the correct order,from beginning to end: I remnant radiation reaches the digital image receptor II the manifest image is displayed on a monitor III the manifest image can be adjusted because it is composed of digital data IV the latent image is processed by the computer

The computer is associated with

Place the following image intensification steps in the correct order,from beginning to end: I electrons are accelerated toward anode II light energy is converted to electrons III electrons strike phosphor and are converted to light IV remnant radiation is converted to light

Another name for remnant radiation is

The image from the output phosphor of the image intensifier is displayed on a television monitor.

Flux gain of the image intensifier is the

An example of an anatomic structure typically imaged with fluoroscopy is the

In the image intensifier,the input phosphor

For every 4-5 cm of tissue,the x-ray beam quantity is reduced by approximately

With the photoelectric interaction,after the incident photon ejects an inner-shell electron,the energy of the photon is

Scatter radiation may

At higher kilovoltages within the diagnostic range
