About this file
This document is a technical specifications sheet for the D-SPECT® Cardio Imaging System, a cardiac imaging device manufactured by Spectrum Dynamics Medical, Inc.
The D-SPECT® Cardio is a pixelated crystal detector system with nine detectors utilizing integrated tungsten collimators and cadmium zinc telluride (CZT) semi-conductor crystals. Key detector specifications include a spatial resolution of 2.46 mm pixel pitch, 1024 pixels per detector (9216 total), energy range of 40-170 keV with extrinsic energy resolution of ≤6.2% at 140 keV, detection efficiency of 80% at 140 keV, and maximum count rate exceeding 1,350,000 counts per second with less than 5% count loss. The system features integrated ECG gating with 8 or 16 frames per R-R interval and automatic beat centering. The patient chair/bed accommodates a maximum static weight of 454 kg (1000 lbs) and dynamic weight of 240 kg (529 lbs), with adjustable height between 60-90 cm from the floor. System dimensions are 190 cm height, 225 cm depth in supine mode, and 155 cm width, with a total weight of 670 kg. Operating conditions require ambient temperature between 15-24°C (59-75°F) and 30-65% relative humidity. The system requires 880 VA nominal power with dual UPS options: 120 VAC (95-151 VAC, 60 Hz) or 230 VAC (181-290 VAC, 50-60 Hz). Minimum room requirements are 9'5" x 8'8" for upright imaging and 9'5" x 11' for supine imaging.
