A
protocol for MRI Quality Control (QC) testing within 15 minutes was developed
in a clinical setting including phantom positioning and image evaluation. The
set-up consisted of a scan protocol using the ACR phantom, based on the ACR
2004 QC Manual. The images were sent from the scanner to a central server
using a DICOM transfer, automatically analysed and compared to predefined
action limits, based on clinical relevance and short-term reproducibility.
Parameters included SNR, ghosting, image homogeneity and 3D geometric
accuracy. Web-based reporting allowed direct feedback at the scanner, while
trend plots provide insight in long-term stability.
