Questions and Answers

What is the purpose of consulting the X-ray imaging manufacturer regarding the system’s default configuration for calibration?

To streamline the testing process and ensure correct data scaling. (correct)

To determine the pulse rate for high-output mode.

To select the FOV for calibration.

To understand how to program every procedure into the system.

How does selecting high-output mode impact the pulse rate in the IXE system?

It decreases the pulse rate compared to low or normal mode.

It maintains a constant pulse rate across all modes.

It eliminates the need for pulse rate adjustment.

It increases the pulse rate compared to low or normal mode. (correct)

What is recommended in selecting procedures for acceptance testing of an IXE system?

Avoid selecting any procedures as it can be time-consuming.

Select procedures based on the system's primary function. (correct)

Choose every available procedure for thorough evaluation.

Opt for procedures related to neurological angiography only.
