The Imaging facility is used for non-invasive magnetic resonance imaging (MRI) studies on Human subjects. It houses a 3 Tesla whole Body (60 cm wide bore) magnet (Siemens MAGNETOM Prisma), with the capability to map brain activity and anatomy, as well as to provide detailed images of whole body organs, muscles and bones. Currently, the system is being used primarily in Neuroscience research for functional brain imaging (fMRI), an advanced imaging technique that enables to map brain activity. In addition, it is used for developing and testing new acquisition and processing tools for imaging and spectroscopy, and for utilizing these tools for characterizing structural, functional and metabolic features, in health and disease.
Our system offers 64 receive channels, MR gradients capable of high speed (80 mT/m @ 200 T/m/s), and parallel transmit technology and applications. The scanner is equipped with unique coils for whole body 1H imaging and spectroscopy (including 32 channel head coil, 20 channels and 64 channels head/neck coils, , a spine 32 matrix coil, 18 channels breast coil, a 18 channels body matrix coil, a knee coil Tx/15 Rx, a Tx/Rx CP head coil, and a 7 cm loop coil). Among the applications that are included on the system are BOLD imaging, diffusion and perfusion imaging, susceptibility weighted imaging, MR angiography, flow measurements, spectroscopy, neuro-imaging, breast imaging, whole-body imaging, and abdominal imaging.
The facility includes a full range of MR compatible peripheral devices that can be used for fMRI studies: A visual system for presenting high-quality visual stimuli in the MRI, An Audio system including headphones and a dual channel MRI microphone system, A 32-channels Brain Products MR compatible EEG, Response devices, An Eye tracking system, a software for real time fMRI analysis that allows neuro- feedback studies, and a system for physiological data monitoring and acquisition during MRI (including pulse, respiration, EMG, EOG, EEG, and skin conductivity).
Additionally the facility includes an MRI simulator – a non magnetic replication of the MR environment to familiarize and train the participants with the research setting.
