Slide 14 of 15
Notes:
I’d like to conclude with this slide, which presents some of the ImPACT evaluation results for the GE Lightspeed Advantage and the Marconi Mx8000. I’ve tabulated the ImPACT Q-factor, for axial and helical post fossa scans, and MTF10% figures for inner ear scans. For those not familiar with these concepts: Q is a measure of overall image quality relative to dose, MTF is a measure of scan plane resolution.
Our results, to date, suggest that: For the axial post fossa scan, in particular, the Q-value for the GE Lightspeed is significantly higher than Q for the Marconi Mx8000. The Mx8000 has the higher scan plane resolution, but, for reasonable noise at narrower slice widths, dose levels are higher.
Regarding the other 2 scanner manufacturers, since the Siemens Somatom Volume Zoom has the same hardware as the Mx8000, we’re expecting similar results. We will be evaluating the Toshiba Aquilion Multi at the end of June.
