How To: 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).
