Siemens 3T Trio with Total Imaging Matrix (TIM) Application Suite

Siemens 3T Trio with Total Imaging Matrix (TIM) Application Suite

The Trio 32-channel system represents state-of-the-art in MRI hardware. It is capable of BOLD EPI, diffusion-tensor imaging, arteriole spin labeling, perfusion and diffusion imaging, and spectroscopy. With 32 usable receiver channels as standard, the system allows for the use of 4 to 16 current-phased array coils to improve sensitivity and speed of acquisition, and is ready for future coil designs with more than 16 elements. Also installed, are the Biopac MP150 Data Acquisition System (BIOPAC Systems Inc., www.biopac.com) and the GSR EDA Galvanic Skin Response Amplifier (GSR100C; BIOPAC Systems Inc, www.biopac.com) – to provide reliable and consistent real-time monitoring of skin conductance responses.  Go to 3T Service Center website >

Siemens Avanto 1.5T Mobile MRI System

Siemens Avanto 1.5T Mobile MRI System

The Avanto is the most advanced system of this strength in the Siemens product line. It features an ultra-short, 150 cm-long whole-body superconductive 1.5T magnet, with 5th generation active-shielding technology with counter coils, External Interference Shielding and excellent homogeneity (based on 24 plan plot, 50 cm DSV type, 0.8 ppm). The system comes equipped with a 12-element Matrix head coil capable of ultra-fast parallel acquisition in 4- (CP mode), 8- (dual mode) or 12- (triple mode) channel settings. This MR system is integrated into a trailer equipped with functional imaging capabilities.

Elekta Neuromag Vector View 306 Channel Meg

Elekta Neuromag Vector View 306 Channel Meg

This 306 channel MEG system is comprised of 204 planar gradiometers and 102 magnetometers and is capable of collecting up to 128 channels of simultaneous EEG data at up to 5 kHz sampling frequency. The planar gradiometers provide sensitivity to sources close to the sensor array whereas the magnetometers provide sensitivity to distant sources, including sources originating from the small head of a child. This provides additional advantages over previous gradiometer-only systems. This system has 24 bit A/D conversion providing the largest dynamic range of currently-available MEG systems.  Go to MEG Land website>

EEG System

EEG System

MRN has a 128-channel BioSemi ActiveTwo electrophysiology system for recording high-density EEG during the performance of cognitive tasks (www.biosemi.com). Electrode caps for four different head sizes are maintained with the system. Acquisition computers use BioSemi software to record EEG data and all stimulus and behavioral response codes for later analysis. Software from Neurobehavioral Systems is available for precise presentation of visual and auditory stimuli and online monitoring of behavioral performance. The event-related potential software system ERPSS (courtesy of Steve Hillyard, UCSD, San Diego, CA) and EEGLab (courtesy of the Swartz Center for Computational Neuroscience, UCSD, San Diego, CA) are available for analysis of the EEG data. MRN also has the capability for concurrent EEG/fMRI using the BrainAmp MR system from brain products.

Mind Input Device

Mind Input Device

Testing subjects in a magnetic environment is a challenge, particularly if the test requires manual switching and/or signal transmission. Subject-response devices must be non-magnetic and preferably non-metallic to reduce unwanted signal noise that would need to be filtered. In addition, these devices must restrain the wrist to limit unwanted movement, while keeping the fingers comfortably positioned on the response switches.
