Preclinical Magnetic Particle Imaging (MPI) scanner

Three-dimensional images at millisecond intervals, providing the potential for real-time 3D imaging in vivo

MPI is a tomographic imaging technique that detects the magnetic properties of iron-oxide nanoparticles injected into the bloodstream to produce threedimensional images. The new technology, invented by Philips, and first introduced in a 2005 Nature paper, gave rise to a high aspirations for a new era in biological imaging.

Now Bruker has combined its expertise in technological innovation with its passion for pushing the boundaries of understanding, and launched the previously only envisioned possibilities to the imaging community.

1,000 Times Faster Than PET
With MPI, imaging of up to 46 volumes per second can be performed, allowing real time imaging of biological processes at an equal or higher spatial resolution than with PET.

100% Animal Visualization
MPI measures the 3D distribution of injected iron oxide nanoparticles using a 25 kHz RF signal. This signal can easily be recorded from any depth within the animal allowing complete flexiblity in choosing areas of interest.

100% User-Friendly
Bruker’s MPI System incorporates ParaVision® 6 and accommodates Bruker‘s multi-modal bed, providing a seamless transition of your animal to and from your
Bruker MRI system.

Unimagined Temporal Resolution
The ability to acquire high time-resolution images in a matter of milliseconds allows for novel applications in medical and industrial research and ultimately patient
care in which temporal resolution is key.
