Facilities and Resources


FastSPECT (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. In progress, completion expected Fall, 2007

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 2008.

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
Testbed 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 four 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.
