Question

A quality assurance test for digital imaging receptors is to check for dark noise. What is the purpose of this test?

A. To determine the maximum exposure that can be detected
B. To listen for static in the reader
C. To assess the level of detector noise in the system
D. To evaluate the monitor's window level settings

Answer 1

To assess the level of detector noise in the system

Step-by-step explanation:

Dark noise is the noise generated in a light sensor photodevice ( such as a

digital imaging receptors) when the photo-cathode is protected from any exterior optical radiation while the device is connected to a power source.

The purpose of any dark noise test is likely to assess the level of detectable noise inbuilt in the system because excessive noise can sometimes reduce the quality of images produced.
