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)
The fEMG Electromyography Smart Amplifier is designed specifically for recording facial EMG signals and electrical activity from other small muscle groups. Use with AcqKnowledge™ software to analyze facial expressions and startle paradigms. BIOPAC’s new Smart Amplifiers are designed for great data. Smart Amplifiers improve performance by amplifying the physiological signal close to the subject, which allows a high-level […]
A System to Measure Physiological Response During Social Interaction in VR Children with Autism Spectrum Disorder (ASD) have a difficult experience in responding to social cues and actions. This pilot study measured the effectiveness of Virtual Reality in creating a social environment for children, measured with a BIOPAC MP Series data acquisition system and Worldviz […]
