Technical specifications, layout, power, and software details for the CMI 2409 Magnetocardiograph.
The CMI 2409 Magnetocardiograph system includes a holder, patient bed, workstation, nine SQUID‑based magnetic field sensors housed in a cryostat, and supporting electronics. It requires a dedicated floor space of about 5 m × 4 m and a clear area around the sensors to avoid RF interference.
Power consumption is 250‑260 W with a 100‑240 V, 50‑60 Hz supply, and the system communicates via a minimum 512 kbps LAN. The cryostat holds 12 L of liquid helium, which must be refilled twice a week, and the Windows‑XP software provides real‑time data acquisition at 1 kHz and advanced analysis tools.
