Computing Facilities

Within the MERF Imaging Facility, research workstations are available for investigators to utilize while imaging and post processing data after it is collected. Both Microsoft Windows and Linux-based workstations are available. Several image processing tools are available on these systems including:

  • BRAINS
  • Slicer
  • FSL                               
  • AFNI
  • MatLab
  • LCModel

We are actively involved with the Iowa Institute of Biomedical Imaging (IIBI) and the Institute for Clinical and Translational Science (ICTS) technical groups to provide administration of our computing resources. IIBI provides system upgrades, on-site technical support and backups for all research machines. ICTS currently provides support for the MRI Research Facility's website, scheduling system and the LCModel server.

The MR Research Facility uses the XNAT (Extensible Neuroimaging Archive Toolkit) open source software platform to manage all MR research images. XNAT allows researchers to access and manage their MR images from a secure repository immediately following a subject's research scan. Subject data is confidential and is available for all current MR research projects.

Other Equipment

The MR Research Facility strives to keep our equipment state-of-the-art and to provide tools to investigators that will facilitate their research projects. Below is some of the equipment we provide to all MR Research Facility users:

BIOPAC Physiological Monitoring System
Includes Photoplethysmograph (PPG), Respiratory, Galvanic Skin Response (GSR), Pulse oximeter, air flow and expired gas analysis.

fMRI MediGoggles
MediGoggles permit subjects who require prescription glasses to see visual stimuli from within the scanner without introducing any safety risks to the subject or artifact in the images. The goggles can be customized from –6 to +6 dioptre in 0.5 dioptre increments and are easy to set up and use.

FOMRI II Fiber Optic fMRI Microphone
The FOMRI II system uses fiber-optic technology and an advanced set of noise-canceling algorithms to reproduce high quality speech from recordings within the magnet and is available for general research usage.

Metrasens FerroGuard Freestanding Metal Detector
The Metrasens FerroGuard metal detector is available at the research suite at L169 MERF and is used to screen every research subject for potential hazardous metallic material. The system is movable and can be adjusted to meet the sensitivity requirements of the location.

Avotec Real Eye 5701 eye tracking system
The Real Eye 5701 uses a fiber optic image guide and an infrared illuminator to monitor subject eye movement. It includes a rear-facing mirror so the subject can view stimulus without any interference from the eye tracking system.
