Gamma Imager

The Gamma Imager:

Compact
All modalities have been designed to minimize total footprint. The Gamma Imager is laptop operated for maximal portability.

Upgradable
Each module can be purchased spearately: switching from one modality to another is fast and easy

Fast and easy
Quantitative information is easy to get from planar scintigraphy or microSPECT

Real time
Micro SPECT and micro CT acquisitions are performed simultaneously, with real time display of both modalities and their registered fusion.

Sub-mm
Sub millimetric spatial resolution with pinhole collimation

Planar scintigraphy

• Gamma Imager is fast, easy to operate and provides reliable quantitative information
• Powerful hardware and software tools generate high resolution scintigraphic images on which regions of interest can easily be drawn for quantitation purpose
• Full body mouse biodistributions are saved in a list mode file allowing separation of the image contributions of different radioisotopes as well as opening any time frame of interest
• Gamma Imager is compatible with a wide range of radioisotopes, including ¹²⁵I, ⁸¹mKr, ²⁰¹Tl,⁹⁹mTc, ¹²³I, ¹¹¹In
• Gamma Imager is operated from a notebook computer and the ideal solution for multi sites experiments including small animal facilities

Micro SPECT

• Switching from planar scintigraphy to microSPECT imaging is very easy and convenient
• This cost effective solution has been designed to provide state of the art performance with minimal footprint, compatible with any lab bench-top
• During acquisition, a micro SPECT reconstructed transaxial slice is displayed and refreshed continuously for close experiment monitoring
• Dynamic studies are available in micro SPECT mode with 1 minute time resolution
• Parallel collimation and high resolution pinhole collimation are available

Micro SPECT / CT

• Gamma Imager - SCT hardware and software provide 3D image fusion that combines microCT high resolution anatomical image with microSPECT functional information
• MicroCT large field of view is compatible with large rat imaging as well as full body mouse imaging
• Gamma Imager-SCT performs both micro SPECT and micro CT acquisitions simultaneously
• Fused micro SPECT / microCT images are displayed in real time and refreshed continuously during the experiment

Fast, easy and quantitative biodistributions
