What is Recording high quality speech during tagged cine‐MRI studies using a fiber optic microphone about?

## Abstract ## Purpose To investigate the feasibility of obtaining high quality speech recordings during cine imaging of tongue movement using a fiber optic microphone. ## Materials and Methods A Complementary Spatial Modulation of Magnetization (C‐SPAMM) tagged cine sequence triggered by an electrocardiogram (ECG) simulator was used to image a volunteer while speaking the syllable pairs /a/‐/u/, /i/‐/u/, and the words “golly” and “Tamil” in sync with the imaging sequence. A noise‐canceling, optical microphone was fastened approximately 1–2 inches above the mouth of the volunteer. The microphone was attached via optical fiber to a laptop computer, where the speech was sampled at 44.1 kHz. A reference recording of gradient activity with no speech was subtracted from target recordings. ## Results Good quality speech was discernible above the background gradient sound using the fiber optic microphone without reference subtraction. The audio waveform of gradient activity was extremely stable and reproducible. Subtraction of the reference gradient recording further reduced gradient noise by roughly 21 dB, resulting in exceptionally high quality speech waveforms. ## Conclusion It is poss
