PHOTO PLETHYSMOGRAPH FOR MRI
Part #: TSD200-MRI

The TSD200-MRI photoplethysmogram (PPG) transducer operates with the PPG100C-MRI to record the blood volume pulse waveform via optical (photoplethysmogram) methods. The TSD200-MRI consists of a matched infrared emitter and photo diode detector, which transmits changes in infrared reflectance resulting from varying blood flow. Blood is highly reflective of near infrared light wavelengths, due to the heme subunit of hemoglobin. When the PPG transducer is placed on the skin, in proximity to capillaries, the reflectance of the infrared light from the emitter to the detector will change in accordance to capillary blood volume. The PPG waveform peaks when capillary blood volume is maximized.

Details

Compatibility


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.

Connections

  • 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.)
