How To: Quick IQ Check

Our in-house Philips training and support engineer, Chris Rinehart, shares his expertise from 18 years in the field on how to ensure Philips Brilliance and Ingenuity systems are performing at their maximum potential.

“At all costs,” says Rinehart, “we want to avoid a misdiagnosis due to an imperfect image. One of the best ways to avoid issues and maintain the highest image quality is the Quick IQ Check.”


Today we’re discussing how to perform a “Quick Image Quality (IQ) Check” on a Philips system. The Quick IQ Check consists of one air calibration and an axial scan, allowing you to measure the main image quality parameter of a CT image.


If your machine’s image quality is low, a radiologist might have difficulty detecting and interpreting the images during a patient’s CT scan. It is important the machine’s IQ meets OEM standards.


Step One: Position the water layer of the head phantom in the center of the scan circle, and zero the couch position.

Step Two: From the Home window, click Quick IQ Check on the utility menu (see Image 1). The Quick IQ Check menu displays.

Step Three: Click the Automatic Test button in the Quick IQ Check menu (see Image 1).

Step Four: Click the Scan button when the Warning sign pops up (see Image 2).
