With a combination of the largest pixelated detector heads in the industry, wide range of single and multi-pinhole collimators, and multiple reconstruction algorithms, the Inveon SPECT system delivers high sensitivity and resolution, and supports many SPECT imaging applications.

Detector Heads
The Inveon high resolution SPECT detectors deliver sub-millimeter resolution with the largest pixelated detector heads in the industry. The SPECT module detects gamma rays from 30 keV to 300 keV, providing sensitivity to the most widely used research and clinical single photon isotopes. Key features of the detector head include:

• Large active area (150 mm x 150 mm) permits greater pinhole magnification, improving sensitivity while maintaining a large field of view (FOV)
• Small detector crystals (2 mm x 2 mm x 10 mm) provide high intrinsic detector resolution

Collimators
Inveon delivers an extensive suite of collimators for every application. The following collimators are available:

• 0.5, 1.0, 2.0, and 3.0 mm single pinhole collimators
• LEAP (low-energy all-purpose) parallel hole collimator for planar imaging
• Mouse brain and mouse whole-body multi-pinhole collimators

Multi-pinhole Data Acquisition and Reconstruction
Multi-pinhole reconstruction and calibration software allows you to produce high resolution images in a fraction of the time required with traditional collimators. Since a single multi-pinhole collimator configuration is not optimal for all preclinical studies, Inveon includes a range of multi-pinhole collimator configurations and an innovative software calibration tool. Operators can select a different multi-pinhole collimator configuration for each study and calibrate the scanner with a simple automated process. This method increases the versatility of Inveon and provides higher quality images than traditional manual calibration methods.
