Low-cost MR-compatible moving heart phantom.
For the development and evaluation of cardiac magnetic resonance (MR) imaging sequences and methodologies, the availability of a periodically moving phantom to model respiratory and cardiac motion would be of substantial benefit. Given the specific physical boundary conditions in an MR environment, the choice of materials and power source of such phantoms is heavily restricted. Sophisticated co...
متن کاملA low-cost mri compatible keyboard
Neuroimaging is a powerful tool to explore how and why humans engage in music. Magnetic resonance imaging (MRI) has allowed us to identify brain networks and regions implicated in a range of cognitive tasks including music perception and performance. However, MRI-scanners are noisy and cramped, presenting a challenging environment for playing an instrument. Here, we present an MRI-compatible po...
متن کاملMR compatible spirometer
Introduction: MR compatible spirometer is needed for (i) monitoring of anaesthetized patients and (ii) sequence synchronization and/or image reconstruction. Patient motion is likely to induce motion artifacts (ghosting) in image thus reducing its quality during MRI acquisitions. When breath-hold acquisitions are not possible, as for uncooperative children, an alternative technique is proposed, ...
متن کاملAn adaptive MR-compatible lens
Introduction We present an MR-compatible adaptive membrane lens, which is integrated into a wide-angle objective to form part of an optical tracking system. This work is motivated by the need for optical head tracking devices for use in prospective motion correction [1], but an alternative application could be high-resolution eye tracking for fMRI. The challenge for in-bore cameras is the limit...
متن کاملAn extension of olfactometry methods: An expandable, fully automated, mobile, MRI-compatible olfactometer.
BACKGROUND fMRI experiments on olfaction offer new insights into the complex, but in contrast to other sensory systems, less studied cognition of odors. To perform these experiments is still a challenge. NEW METHOD To address the challenge posed by MR settings, an olfactometer design is presented including specific improvements to the limited number of already existing olfactometers. Innovati...
