Dual Channel Gating Systems released
MRI Gating System for Two Signals
Respiration and ECG or BP
The DTU200 is a dual channel gating system for small animal MRI applications (human system available). It sends cardiac trigger pulses to the MRI when a respiration signal is in the quiet phase. Pre-processing filters and gain controls further refine the quality of the signal and ensure reliable triggering.
- Scan from 1-8 ECG pulses after fall of RSP where first acceptable ECG is >100 msec after RSP fall
- Blanking – adjust from 50-300 msec (this will shut off ECG from reaching trigger)
- Delay – adjust from 1-50 msec.
- Trigger pulse – fixed at 100 µsec
Scan time = Blanking – Delay
