G-SPECT is an innovative, high-performance full-ring SPECT system developed for large animals. G-SPECT offers an up to 2.5-fold improvement in spatial image resolution over typical current SPECT systems and an up to twenty-fold reduction in SPECT radiopharmaceutical use to obtain conventional SPECT resolutions. The system is suitable for imaging a wide range of isotopes, including all low- and medium-energy SPECT isotopes such as 201Tl, 99mTc, 123I, and 111In.
Moreover, for research applications, the system has the unique capability to image at unprecedented high resolutions high-energy theranostic isotopes such as 131I, 225Ac/213Bi, and 212Pb and perform targeted PET, including simultaneous multi-isotope PET imaging.
Another exclusive research feature is concurrent PET/SPECT imaging, which makes direct comparisons between co-injected SPECT and PET tracers under identical physiological conditions possible since their images are co-registered in space and time.
The G-SPECT is mainly based on Milab’s proven technology for pre-clinical diagnostic and theranostic applications, including patented stationary multi-pinhole (SMP) image collimation and magnification technologies. With its unique potential for high resolution and fast list-mode acquisitions, groundbreaking static and dynamic SPECT applications can now be translated to large animals.
