Acoustic noise characteristics of a 4 Telsa MRI scanner.
PURPOSE To quantify the acoustic noise characteristics of a 4 Tesla MRI scanner, and determine the effects of structural acoustics and gradient pulse excitations on the sound field so that feasible noise control measures can be developed. MATERIALS AND METHODS Acoustic noise emissions were measured in the ear and mouth locations of a typical adult. The sound pressure measurements were acquire...
متن کاملExperimental Study of Active Acoustic Noise Control in a 4T MRI Scanner In-Situ
Introduction The acoustic noise generated from the MRI system is a serious safety concern as well as a technical challenge for MR and acoustic noise control scientists. The emitted high noise levels can be both annoying and harmful to patients and healthcare workers, especially after long term exposure. Although various passive methods have been proposed to deal with this problem, active noise ...
متن کاملBlind Dereverberation for MRI Acoustic Noise
Abstract. In Magnetic Resonance Imaging (MRI) room, strong acoustic noise during the scan not only creates harmfully annoying environment but also interferes with brain activation response. The presence of reverberation in the MRI environment interferes with efficient noise canceling techniques. In this paper, we present a blind dereverberation method for estimating the broadband MRI acoustic n...
متن کاملSpeech perception in MRI scanner noise by persons with aphasia.
PURPOSE To examine reductions in performance on auditory tasks by aphasic and neurologically intact individuals as a result of concomitant magnetic resonance imaging (MRI) scanner noise. METHOD Four tasks together forming a continuum of linguistic complexity were developed. They included complex-tone pitch discrimination, same-different discrimination of minimal pair syllables, lexical decisi...
متن کاملA Structure Design Method for Reduction of MRI Acoustic Noise
The acoustic problem of the split gradient coil is one challenge in a Magnetic Resonance Imaging and Linear Accelerator (MRI-LINAC) system. In this paper, we aimed to develop a scheme to reduce the acoustic noise of the split gradient coil. First, a split gradient assembly with an asymmetric configuration was designed to avoid vibration in same resonant modes for the two assembly cylinders. Nex...
