A desktop preclinical 3D SPECT platform for fast in vivo screening and longitudinal imaging of gamma- and alpha-emitting radiopharmaceuticals

From fast planar imaging to dynamic 3D SPECT

The γ-eye™ system now supports tomographic 3D SPECT imaging, enabling enhanced spatial assessment while preserving its compact footprint and simplicity

  • 3D SPECT imaging for whole-body spatial assessment of radiopharmaceutical distribution and longitudinal evaluation across different time points
  • 4D dynamic SPECT imaging, enabling quantitative kinetic analysis of radiotracer uptake
  • Fast planar imaging for simple and time-efficient screening, such as the assessment of whole-body distribution and compound kinetics
  • High-throughput imaging of up to four mice simultaneously or one rat*

 

*Available only for planar imaging

From multi-angle acquisition to 3D SPECT

The γ-eye™ uses fast 360° rotation to acquire whole-body projections from multiple angles, enabling tomographic 3D SPECT reconstruction with short acquisition times.

  • Multi-angle whole-body acquisition over 360°, with planar projections acquired every 5°
  • 3D SPECT reconstruction from 72 acquired projections, providing volumetric information in multiple anatomical planes
  • Dynamic 4D SPECT imaging, with sequential reconstructed volumes to follow radiotracer kinetics over time
High Throughput configuration

High-throughput imaging for multi-animal screening

The γ-eye™ is also available in a High Throughput configuration, designed for efficient planar imaging of larger study cohorts while preserving the core functionality of the standard system

  • Field of view of 100 × 200 mm, providing extended coverage for multi-animal imaging
  • Planar imaging of up to 4 mice simultaneously or 1 rat, supporting efficient screening workflows
  • High-throughput performance of more than 110 mouse scans per day, increasing daily imaging capacity for larger study cohorts
