Keywords: New Devices, New Devices, Force Measurement
Motivation: Conventional load cells are not MRI-compatible, and MRI-compatible fiber optic force sensors are expensive and require specialized data collection systems.
Goal(s): Our goal was to develop and test a low-cost, MRI-compatible device for continuous force measurement.
Approach: We developed a hydraulic-based system for measuring continuous compressive forces within the magnet bore during scans.
Results: Pre-cycling increased the measurement repeatability of the device. The device was completely MRI-compatible and measured continuous compressive forces while simultaneous MRI data was acquired.
Impact: Our newly developed device is an inexpensive option for measuring continuous compressive forces during simultaneous MRI scans and is particularly useful for researchers who want to use a conventional electronic data acquisition system.
