Radio Frequency Quadrature Artifact 
Quick Overview
Artifact Information
NAME
Radio frequency quadrature
DESCRIPTION
Bright spot in the center of the image, ghosting
REASON
RF detection circuitry problem
HELP
Call the service
Radio frequency quadrature artifacts occur when the detector channels of the quadrature detector are disturbed.
A DC offset of one amplifier output can e.g., produce a bright point in the center of the field of view (see also central point artifact), or a higher gain of one detector channel can generate diagonally ghosting.
mri safety guidance
Image Guidance
Radio frequency quadrature artifacts are technical faults and must be eliminated by the service.
