Exam 10: Dynamic Imaging: Fluoroscopy

The analog to digital converter:

Which of the following does not require any additional devices for spot filming during the fluoroscopic procedure?

Use of which of the following systems will result in less radiation dose to the patient?

A typical high-resolution monitor will have:

In fluoroscopy,shape distortion is caused by:

Distortion of the fluoroscopic image that appears as unequal magnification is:

Each electron that interacts with the output phosphor will result in significantly fewer light photons being produced in comparison to the number of light photons it took to release that electron.

Early versions of digital fluoroscopy used the standard system and added:

The purpose of a camera tube or CCD is to record the fluoroscopic image.

Which of the following produces an image with more noise?

Fluoroscopic equipment should be inspected every:

The input phosphor is ______________ than the output phosphor.

The process that the exit radiation from the anatomic area of interest interacts with the input phosphor for conversion to visible light,which are converted to electrons by a photocathode,then focused by electrostatic focusing lenses,and accelerated toward an anode to strike the output phosphor is:

___________ imaging is accomplished with fluoroscopy as opposed to radiography.

Releasing the pressure applied to the ________________ will terminate the radiation exposure during fluoroscopy.

Which of the following requires more radiation to produce quality fluoroscopic images?

The __________________________ consists of a light-emitting material (like cesium iodide)to absorbs x-rays and emits light.

Which of the following has the possibility of demonstrating veiling glare and pincushion distortion?

A disadvantage of using magnification mode during fluoroscopy is:

Which of the following is easier to move around and allows better access to the patient during a procedure?
