MRI Subject Feedback

BIOPAC offers a range of subject feeback devices for use inside the MRI. These transducers provide accurate results inside the scanner without the need for additional filtering or signal conditioning. The Hand Response Pump Bulb Transducer uses no electrical components which greatly simplifies the setup procedure. See each product page for conditions related to MR use and list of components.

TSD115-MRI Variable Assessment Transducer

The TSD115-MRI incorporates a slide control with graduated scale that allows the user to gauge their subjective response to a variety of different stimuli. Multiple TSD115 transducers can be used simultaneously allowing several people to answer the same question or otherwise respond to stimuli. The transducer is lightweight and fits easily into the subject’s hand or lap. The TSD115-MRI includes an 8m cable which terminates in an SS type connector, with pinout to accommodate MRIRFIF pins (1-5).

This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.

Hand Response Pump Bulb Transducer

The Pump Bulb Transducer works well when the subject has to give a Yes/No or On/Off Response. The subject holds the bulb in one hand and squeezes to give a response. Use two bulbs for more complicated responses. The bulb is attached to a length of tubing that connects to a TSD160A High Sensitivity Differential Pressure Transducer.

Interface:

  • DA100C General Purpose Transducer Amplifier

TSD121C-MRI Hand Dynamometer

Use to measure clench force. The lightweight, ergonomically designed transducer provides direct readings in kilograms or pounds. The isometric design improves experiment repeatability and accuracy. This device has electrical components and requires the filt

Interface:

  • MECMRI-DA
  • DA100C General Purpose Transducer Amplifier

TSD110-MRI Pressure Pad / Respiration Transducer

The TSD110-MRI can be mounted in the scanner so that the subject can tap it to respond to a stimulis. Multiple transducers can be used for more complex applications.
