FastSPECT I (Fast Stationary SPECT)
Dynamic SPECT system for mice and rats. Uses 24 modular scintillation cameras, each with one pinhole. No motion of aperture or detector, so true 4D imaging is possible.FastSPECT II
Upgraded version of FastSPECT. Better resolution (1-2 mm for normal configuration), improved electronics, list-mode data acquisition, flexible aperture assembly.NanoSPECT
FastSPECT II as configured with 100 µm D pinholes, 18X magnification, 1 nanoliter voxels over 5 mm field of view.FaCT (FastSPECT + CT)
FastSPECT II augmented with cone-beam, helical scan computed tomography system.BazookaSPECT
Photon-counting detector with a fast-readout CCD camera and an image intensifier. Online maximum-likelihood estimation of scintillation position and energy. Detector resolution about 60 µm. Used with pinholes or coded apertures for small-animal SPECT.FastSPECT III
Next-generation stationary SPECT system, being designed for mouse brain imaging. Uses multiple BazookaSPECT detectors. Completion expected early 2009.SemiSPECT
The FastSPECT concept implemented with cadmium zinc telluride (CZT) detector arrays. Submillimeter resolution for mouse imaging.Dual-modality CT/SPECT
A single CZT detector array with a microbore collimator for SPECT, simultaneous cone-beam CT.M3R (multimodule, multiresolution) SPECT system.
Test bed for the study of image quality. Four modular scintillation cameras with easily interchangeable pinhole plates and variable magnification. Used for optimizing task performance for a specified class of objects.Adaptive SPECT prototype
Variation of the M3R concept which allows adaptation of the imaging configuration in response to initial data obtained on a specific subject. Goal is to achieve optimum task performance for that subject rather than a prespecified class of subjects.SiliSPECT
Experimental system for ultrahigh-resolution of small animals at low gamma-ray energy. Uses 4 crossed-strip silicon detector arrays with 50 µm strips–a 4 megapixel gamma camera.ModPET
Experimental small-animal PET system using monolithic sodium iodide crystals. Work in progress.Direct electron imager
An in vivo autoradiography system for high-resolution imaging of beta particles, positrons, or conversion electrons from radionuclides.Other equipment
