The MILabs VECTor7 is a PET/SPECT system with an ultra-large detector surface, featuring one M7 collimator and one M5 collimator for mice and rats. Designed for high-resolution imaging, it supports SPECT resolution down to 0.13 mm ex vivo and 0.25 mm in vivo, as well as 18F PET imaging with resolution <0.6 mm. It offers positron-range-free imaging of PET isotopes and simultaneous multi-isotope PET imaging at <0.75 mm resolution. It is the only system on the market suitable for quantitative sub-mm imaging of high-energy theranostic isotopes.


  • Integrated high-resolution CT subsystem.
  • Integrated Optical Imaging subsystem.
  • Each modality can be performed separately: PET/SPECT/CT/OI
  • Multi-mouse bed with gas anesthesia and heating module for maintaining optimal conditions.
  • Cardiac and respiratory monitoring and gating with temperature control.
  • Positron-range-free PET for specific isotopes like 124I, 76Br, and 82Rb.
  • Dual-isotope PET compatible with Positron-range-free PET.


The system comes with an acquisition PC and a reconstruction PC with basic image processing and analysis software.

  • VivoQuant Viewing and Analysis Software.
  • Imalytics Preclinical Software for comprehensive modality analysis.

Performance Levels

The U-CT system supports ultra-fast scans with low X-ray radiation doses. It can be integrated with MILabs PET, SPECT, and OI modules. The different modules can be performed separately It is suitable for imaging mice and rats. Performance levels include:

  • Standard CTSD: Reconstructed voxel resolution down to 30 μm.
  • High-Resolution U-CTHR: Voxel resolution down to 10 μm.

Optical Imaging

The U-OI system enables fully automated optical imaging using bioluminescence, VIS-NIR fluorescence, and Cherenkov imaging. It features ultra-sensitive imaging technology with automatic focus, a computer-controlled filter wheel, and supports 3D/4D fluorescence and bioluminescence tomography.
