Inviscan IRIS PET/CT scanner for in vivo preclinical imaging

The IRIS PET/CT scanner, by Inviscan, is dedicated to in vivo preclinical imaging research on small animals such as mice and rats and is well suited to medical research applications such as oncology, neurodegenerative diseases and cardiac studies.

The easy-to-use and high-sensitivity scanner has a PET spatial resolution near 1 mm and a full mouse field of view, and is CT optimised for speed. It also features sensorless cardiac and respiratory gating as well as 4D CT imaging technology.

The IRIS PET/CT scanner is available in single-modality PET, CT or dual-modality PET/CT. IRIS technology is flexible and an IRIS PET or CT scanner can be upgraded to PET/CT at a later stage.

Specifications for PET include: sensitivity of >9% (250–750 keV); spatial resolution of <1 mm (CFOV), average 1.1 mm; axial FOV of 96 mm; trans-axial FOV of 81 mm; energy resolution of <13%; and timing resolution of 1.8 ns.

Specifications for CT include: X-ray tube 20–80 kV, 0–1 mA, 80 W max; detector imaging area of >11.4 x 14.5 cm²; scan time of <7.3 s (ultrafast mode), 20 s (speed mode) or 1 min (high-resolution scan); low dose <6.5 mGy; resolution of 73 μm @ 10% MTF, minimal voxel resolution of <30 μm; axial FOV of >90 mm; dynamic 4D acquisition; and software-based respiratory and cardiac gating.
