BIOPAC Expands MRI Product Line

MRI Solutions for Human and Animal Life Science Research

BIOPAC offers data acquisition systems, MRI Smart Amplifiers, transducers, stimulus options, electrodes, and leads with advanced software tools for safe data collection, subject monitoring, and cleaner physiological signals in the MRI environment. BIOPAC has expanded its line of specialized MRI products. MRI Smart Amplifiers and the MRI Cable/Filter systems provide isolated and RF-filtered interfacing between the subject/MRI chamber and the MRI control room to improve signal quality and optimize safety.

With BIOPAC’s expanded line of MRI Smart Amplifiers and compatible transducers, you can record physiological signals such as: ECG, EEG, EGG, EMG, EOG, noninvasive blood pressure for human and animal, pulse, respiration, SpO2, temperature, electrodermal activity, hand grip strength (dynamometry), finger twitch, and a variety of pressure-based signals.

For small animal cardiovascular and neuro studies, use the TSD104A-MRI Pressure Transducer or a Micro Pressure Measurement System to record pressure signals such as BP, LVP, and cranial pressure. Measure microvascular blood perfusion with the Laser Doppler Flow System. See fMRI App Notes for more on connections, analysis tools, and safety when recording physiological data in MRI or fMRI.

BIOPAC’s MRI solutions include: Airflow & Gas Analysis Biopotential Signals Gating (Trigger/Synch); Blood Pressure; Electrodermal Activity; Laser Doppler Flow; Pulse; Respiration; Stimulation; Subject Feedback; Temperature; and more. Transducer signals are typically high level and slow moving. These two features allow the transducer signal to be easily filtered to remove MRI artifact, if any.

Systems include AcqKnowledge software with rich display and monitoring features, plus automation and scoring routines to provide a flexible solution for life science research. MRI Smart Amplifiers incorporate advanced signal processing circuitry which removes spurious MRI artifact from the source physiological data.

Use the BIOPAC Remote Monitor licensed feature for a simplified view of subject data across an IP network on another computer or a mobile device. The monitor displays trend data and current data values. It’s a convenient way to view the data on other computers in the MRI suite.

Each MP System includes all the necessary hardware and software required to turn any computer into a powerful data acquisition workstation specifically designed for life science applications. The MP System will reduce your equipment setup time and increase the quality of your physiological data. The MP System gives you publication results with minimum effort. MP Systems and amplifiers are placed in the MRI Control Room, and specialized cable systems optimize data quality with isolated and RF filtered interfacing between the subject/MRI Chamber and the Control Room. Filter leakage currents and dielectric isolation satisfy IEC60601-1.

BIOPAC’s range of amplifiers further enhances your ability to create a system to suit your application requirements. Amplifiers snap together and pull apart for simple substitutions. The system is small and easily transported from the lab to the MRI Control Room. To put together a system for your specific needs, select a Starter Systems, then add the amplifier modules, transducers, isolated RF cable/filter systems, and electrodes to match your research design.
