Spectrum - Model D-SPECT Series - Cardiology Digital Spect Imaging System
The D-SPECT open gantry design is about patient access and comfort. The scanner is designed so nuclear departments or cardiology offices can image even the most challenging patients. During a cardiac scan, such as myocardial perfusion imaging, there is no gantry motion, so patients can easily be positioned and scanned. The chair provides the flexibility to image the patient supine position, upright position or any angle in between. It supports up to 1000lb/454kg.
Spectrum Dynamics’ unique implementation of CZT solid-state detectors has established the design as the gold standard of CZT-based SPECT cameras used in Nuclear Medicine.
CZT detectors technical advantages for SPECT imaging, when compared to traditional NaI detectors, include higher sensitivity, improved energy resolution, and increased sensitivity.. CZT eliminates the need for photomultiplier tubes.
Spectrum Dynamics combines the CZT modules in a proprietary and patented column design. These detector columns swivel during a SPECT scan acquisition, while the gantry is in a fixed position and close to the patient There is no perceivable motion for the patient during the scanning session. This design is beneficial in more than one way: focus the field of view in a specific or an for even higher sensitivity gains during a scan acquisition; 3D dynamic imaging of any organ; lower dose protocols; scanner throughput.
The D-SPECT camera contains 6 or 9 detector columns. Spectrum Dynamics’ patented swivel head detectors are pixelated to align with the parallel hole tungsten collimators to allow for faster acquisition.
Each scanner design is optimized to allow for the gantry to be positioned as close as possible to the patient: this ensures the
best image quality in a nuclear medicine scan: proximity with no gantry rotation or motion.
- In-gantry patient positioning guide with touch screen displays positioning information of current scan and previous scan.
- Screen displays pre-scan image for scan start confirmation.
