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 B-GA12S HP gradient set (660 mT/m, 4570 T/m/s microsec risetime) and a B-GA12S HP shim system with 114.5/198 mm inner/outer diameter, shim coils providing z0, x, y, z, 2xy, x2-y2, z2, zx, zy, z3, z4 shims.
