Functional X-ray Imaging Benchwork

The X-ray fluorescence (XF), X-ray luminescence (XL), and X-ray transmission (XCT) imaging benchwork consists of:

(1) a monochromatic source that delivers a pencil beam of 17.4 keV X-rays with diameter tunable from 30 to 100 µm,

(2) a conventional micro-focus (25 µm) polychromatic X-ray source equipped with multiple filter configurations,

(3) a direct-detection deep-depleted X-ray CCD camera coupled to user-adjustable (slit or multiple-pinhole) apertures,

(4) an iXon Andor EMCCD camera with various optical filters, and (5) a Zyla 5.5 CMOS X-ray camera with a pixel size of 6.5µm.

The DE-SPECT SYSTEM

The Dynamic Extremities (DE-) SPECT system is a stationary and organ-dedicated clinical SPECT system based on 48 1-cm thick 3D-position-sensitive Cadmium Zinc Telluride (CZT) detectors and dynamic dual-field-of-view synthetic compound-eye (SCE) collimators. The scanner is designed and optimized to perform hyperspectral imaging of lower extremities in patients suffering of peripheral vascular diseases (PVD).

The MRC-SPECT-2 SYSTEM

The MRC-SPECT-2 system is a MR-compatible preclinical SPECT imaging system. The system presents 24 2-mm thick CZT crystals and a compound-eye collimator with 96 knife-edge pinholes. More details about the multi-detector readout circuitry can be found HERE. The system is currently installed at the Integrated Small Animal Imaging Research Resource (ISAIRR) at University of Chicago.

The ALPHA-SPECT-MINI SYSTEM

The Alpha-SPECTmini system is a high-performance small-animal system for XFCT and targeted alpha therapy imaging applications. The system is based on 24 1-mm CdTe detectors and it is equipped with interchangeable multi-slit and high-energy multi-pinhole collimators. The system is currently installed at the Department of Radiology and Radiological Science at the Johns Hopkins Medical School.
