7T Animal Scanner

Bruker 7T Biospec Animal Scanner
7T Bruker Biospec Scanner

The Bruker Biospec 7T/30 Scanner is capable a full diversity of modern neuroimaging including structural MRI, functional MRI, diffusion MRI (DTI), double pulsed-field gradient (DPFG), magnetization transfer, susceptibility weighted imaging (SWI), MR spectroscopy and many more. Most of the studies performed in the center are in vivo imaging of rat and mice using designed animal beds for each mice and rats with tooth bar, an artificial respiration mask and water circulation unit to regulate body temperature.

 

 

Shim System

 

The scanner is equipped with a BGA-12 Gradient set (400mT/m, 100microsec risetime) and a B-S20 shim system with 283 mm inner diameter shim coils providing z0, z2, z3, z4, xz, yz, xy, x2-y2,z(xy), z(x2-y2), z2x and z2y shims.

 

 

Coil Configuration
