Introducing the X-SPECT® Subsystem

triumphiisystemspectTriFoil's X-SPECT subsystem offers superior imaging capabilities for use in small animal in-vivo studies. By combining two essential imaging technologies on to one scanner, the X-SPECT system allows for the ability to capture two types of images in small animals at the same time and improve efficiency in the research lab. This subsystem provides high quality preclinical SPECT imaging using solid-state Cadmium Zinc Telluride (CZT) detector technology. The X-SPECT subsystem increases the sensitivity possible with SPECT, yielding higher resolution at lower dose levels and faster scan times.

  • System accommodates up to four CZT gamma cameras.
  • High energy resolution (better than 4.5 % at 140 keV) generates clear images by reducing radiation scatter, and is well suited for simultaneous multi-isotope imaging.
  • Compact, high spatial resolution gamma cameras in combination with single and multiple pinhole technologies delivers high sensitivity and SPECT resolution.
  • Wide gamma-ray energy range of 25-250 keV to cover a variety of isotopes (e.g. 99mTc, 123I, 125I, 201Tl, and 111In) for imaging.
  • The Variable 'Radius of Rotation' for SPECT (1.5 to 17.5 cm) enables flexibility for imaging studies allowing the user to zoom in on a specific organ, or image an entire animal.
  • The high sensitivity allows for a significant reduction in acquisition time or delivered dose.
