Figure 3.2 Gantry schematic block diagram, CardioMD Series I and II systems
On Series I and II CardioMD systems, the side panel contains all interface connectors to
peripheral devices, including the acquisition PC and the hand controller. A 115 V AC power
supply output is available for the acquisition PC, along with IEEE 1394 FireWire communication,
which is routed directly to the detectors. An input connector for an ECG trigger is also provided.
This R-wave input is also routed directly to the detector EDC modules where the trigger events
are encoded into the data stream going to the PC.
Interconnections of Series III and earlier systems are shown in the diagrams Figure 3.3 and Figure
3.4.
