Description
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.
