nanoScan® PET/CT


Real dynamic PET-system designed for quantitative studies

The nanoScan® PET system is equipped with the finest detector crystal needles ensuring high spatial resolution down to 700 μm in vivo.

Quantitative results delivered over the widest range of radioactivity levels from 60 Bq to 60 MBq (1.6 nCi – 1.6 mCi). It covers the full range of PET applications from long-term cell tracking to dynamic studies with 11C- and 15O-labelled radiotracers in rats.

Large ring diameter allows imaging of multiple mice and large animals, while the unique, Tera-Tomo™ 3D iterative reconstruction based on real-time Monte Carlo simulation ensures homogeneous image quality over the entire field of view.
Open access to the animal during PET scanning gives full control over the animal studies.
The PET system is also available in triple-modality combination with our high-end SPECT (nanoScan SPECT/CT/PET) or fully integrated with MRI (nanoScan PET/MRI).

Features & Benefits

Resolving precise details with 700 μm spatial resolution

  • Finest lutetium oxyorthosilicate (LSO) crystal needles provide precise signal localization preserving spatial information in raw data
  • Tera-Tomo™ 3D PET iterative reconstruction with real-time Monte Carlo based physical modelling unveiling the tiniest details on the image
  • Large ring diameter and statistical depth of interaction compensation offer homogeneous image quality over the entire field of view

Uncompromised applications with very low level of radioactivity

  • Thick LSO crystals for excellent sensitivity
  • Advanced corrections (random, scatter, LSO background etc.) ensuring quantification at low activity levels
  • Best minimal detectable activity on the market: 60 Bq (1.6 nCi)
  • Inherently optimized for longitudinal studies e.g. long-term cell tracking

Coping with count rate: mastering studies with high dose

  • Multichannel read-out electronics with ultra-fast data processing and advanced dead-time correction
  • Exceptional count rate performance – peak noise equivalent count rate (NECR) for mouse is 850 kcps @ 60 MBq
  • Fully quantitative at 60 MBq (1.6 mCi) and beyond
  • Suitable for dynamic imaging of large animals or for dynamic scanning of up to four mice simultaneously
  • Optimal for imaging of isotopes with short half-life (11C, 13N, 15O etc.)

Largest transaxial field of view

  • Wide bore diameter of 16 cm allowing open access to the animals
  • Large transaxial field of view of 12 cm
