Measuring vibrations in MRI with an inexpensive device

Correspondence: [email protected] Vibrations of MRI systems impair the image quality and the results of studies in different ways. In functional studies the noise could affect the subjects brain activation [1] whereas in structural studies, especially diffusion tensor imaging (DTI), the vibrations could have direct or indirect impact on the image itself [2]. Setups for measuring and simulating vibrations have been proposed before [3,4]. But most of them are not readily available or suitable for multicentric studies. Here we demonstrate the use of a general purpose accelerometer and an electronics prototyping platform to quantify the occurring frequencies and the acceleration. Ergebnisse Hintergrund Back round
