MRI RF-Coils

Preclinical magnetic resonance imaging of laboratory animals is often mandatory for the in depth understanding of biological and pharmacological processes and has become the accepted gold standard for many investigations. The range of applications has expanded dramatically over the past few years - especially through the introduction of dedicated RF-coils.

Choose from a wide range of different designs, optimized for various applications. Volume coils ensure optimal image homogeneity, while surface
coils guarantee the highest available sensitivity through application optimized geometry and integrated preamplifiers. Multi-channel array designs offer an even greater flexibility by enabling accelerated parallel acquisition applications.

The patented MRI CryoProbe™ opens up new sensitivity dimensions with a x2 to x5 sensitivity boost. Identify finest anatomical details at near cellular resolution and save precious instrument time with a proven up to x6 accelerated throughput.

Fully automatic hardware recognition is included in all coils and ensures safe operation of up to four different coils at a time. Easy-to-use positioning, pneumatic fixation and color-coded plugs ensure reliable coil handling in seconds. The automatic recognition of Bruker coils guarantees safe operation within the power limits of each individual coil. Thus, the non-expert can produce fast and reliable results, whilst the comprehensive flexibility and operation needed by the MR researcher is never compromised.
