磁粒子成像（MPI）小动物活体

Three-dimensional images at millisecond intervals, providing the potential for real-time 3D imaging in vivo 毫秒间隔三维成像，可做活体实时三维成像

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 比PET快1000倍
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 100%的动物可见性
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  100%用户友好
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 超乎想象的分辨率
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.

Partnering in Innovation

The result of an exclusive collaboration, the MPI system combines Bruker’s leading expertise in analytical magnetic resonance instruments and preclinical

Magnetic Resonance Imaging (MRI) with Philips’ unique strengths in medical imaging.

MPI is a completely new preclinical imaging technique with enormous potential to deliver new insights into disease processes at the organ, cellular and molecular level. With the new MPI system, Bruker further complements its extensive preclinical imaging product portfolio that includes MRI, PET, SPECT, micro-CT, optical molecular imaging and X-ray.
