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 ┬Ásec

Scan time = Blanking – Delay
