Understanding Automatic Exposure Control

Front

What type of technique adjustment is usually required for destructive diseases in radiography?

Back

Decrease

Front

What is the primary role of backup timers in Automatic Exposure Control (AEC) systems?

Back

To prevent excessive exposure

Front

Is AEC appropriate for every exam in the radiography department?

Back

False

Front

Which factor should be decreased to eliminate motion in radiographic imaging?

Back

Time

Front

What principle does a phototimer AEC system operate on?

Back

It uses a light-sensitive device to measure the amount of radiation.

Front

Define Automatic Exposure Control (AEC).

Back

AEC is a system that automatically adjusts the exposure time in radiography to achieve optimal image quality.

Front

What is the consequence of using AEC inappropriately?

Back

It can lead to underexposure or overexposure of the radiographic image.

Front

What does SID stand for in radiography?

Back

Source-to-Image Distance.

Front

How does increasing kVp affect image quality in radiography?

Back

Increasing kVp enhances image contrast and reduces patient dose.

Front

What is the function of a photomultiplier tube in AEC systems?

Back

It detects the amount of radiation and sends a signal to terminate exposure.
