The transducer optics are designed to sense diffuse surfaces, including the skin surfaces of finger or toe. The transducer is sensitive to Blood Volume Pulse (BVP) via photo-plethysmographic methods.
The Diode and Phototransistor are mounted side by side on parallel axis in a black polyurethane housing. The Phototransistor is encased in a dark epoxy package which filters out visible ambient light. The transducer has a shielded 3-meter cable.
The ergonomic housing design improves contact with the subject and helps reduce motion artifact.
The TSD200-MRI only operates with the PPG100C-MRI amplifier.
- For MRI applications: Use the MECMRI-TRANS Cable/Filter to connect the TSD200-MRI to the PPG100C-MRI. See BIOPAC Application Notes regarding the proper installation of MECMRI cables for recording in an MRI environment.
- For non-MRI applications: Connect the TSD200-MRI directly to the PPG100C-MRI.
MRI Use: Conditional to 7T
Condition: Conductive parts of transducer are electrically and thermally isolated from subject. (See Specifications for components.)
