Paper Abstract

We report here the adaptation of an existing optical respiration monitor, the fiber optic respiratory plethysmograph (FORP), to act as a gating tool to compensate for respiratory motion that occurs during scans in magnetic resonance (MR) scanners. The instrument is based on the principle of bending losses in optical fibers, and features a user-friendly graphical interface written in Visual Basic for Windows. One of the novelties of the system is the use of an optical feedback channel to instruct the subject to inhale, exhale or hold their breath. Results are presented that demonstrate that the instrument is useful in helping a test subject reproduce accurate breath holds.
