SPECT Cardiac Imaging System Incorporates CZT Modules
Spectrum Dynamics' D-SPECT (single photon emission computed tomography) system uses a cadmium zinc telluride (CZT) nuclear imaging detector, which enable high resolution, low-dose nuclear imaging.
The design incorporates nine rotating columns of CZT detectors that are able to focus on specific anatomical points in the body, thereby improving the signal-to-noise-ratio. This also eliminates the need to rotate the gantry or the patient to sample the organ of interest, improving patient comfort, reducing claustrophobia and patient motion problems.
Solid-state CZT based detectors, combined with advanced new reconstruction algorithms, provide the foundation for rapid imaging and clinical applications not possible with conventional sodium iodide based detectors. They also enable dramatic reductions in radiation dose to the patient and significant improvements in image quality.
The Redlen M1762 nuclear imaging module provides a 40 x 40 mm CZT imaging array with 256 pixels. The module provides direct digital readout and averages less than 6 percent energy resolution for Tc-99 based imaging. The module provides a key building block to enable a new generation of direct conversion low-dose, high-resolution nuclear imaging cameras.
