BGA-S Gradient Series

High Performance Integrated Gradient and Shim Systems

An increasing number of preclinical MR imaging applications demand ultra-high magnetic fields with increased requirements to gradient and shimming technology. Bruker BioSpin MRI therefore is introducing the BGA-S series, a complete new series of high performance actively shielded gradient systems with integrated shim coils.

Superior performance on the following major characteristics can thus be achieved:

Ultra high gradient strength
Very short gradient slew rates
Excellent gradient duty cycle (independent of shims and gradients)
Optimal gradient linearity
Very high gradient shielding quality
Maximal shim strength

The new BGA-S series is available for BioSpec^®, PharmaScan^® and ClinScan^® systems.
