Varian 4.7T Research MRI
- Don Wilson (Unlicensed)
Device use type: 2 (Fee for service)
Location: University Hospital
Description:
The 4.7T system is very unique; the strongest full-body system in Canada* and only one of the two systems in the world at this field stregth. It provides a good balance between taking an advantage of the high-field system while avoiding some of the downsides of the ultra-high field systems.
The system is dedicated to Allan H. Owen and his family for a donation that helped to secure funds not only for this particular system, but also for the whole facility.
The system has been recently (in 2008) upgraded with a new gradient and shim coil sets, and enable various applications:
high resolution brain imaging
functional imaging (fMRI)
brain spectroscopy
sodium brain imaging
knee imaging (sodium and proton)
Features:
Sequences available
Imaging
