In Vivo Imaging

The purpose of the image processing module is to facilitate the acquisition and analysis of fMRI signals, functional optical images of visual cortex and images of normal and diseased retina.

The neuroimaging engineer is responsible for developing, implementing, and maintaining software/hardware systems for image segmentation, image registration, image display, and statistical analysis of fMRI and optical imaging data.

VVRC members should contact the neuroimaging engineer directly for information or to request services.

Hardware and Software at the 3T

Patrick Henry is primarily responsible for the hardware used for stimulus presentation and behavioral data collection at the 3T scanner. Specifically, he is responsible for the proper functioning of the Mac and PC computers and monitors for stimulus presentation, and for the audio-visual presentation systems (e.g. projectors, screens, goggles, head phones), and non-imaging-related data collection (eye tracker). Pat is also responsible for installation and maintenance of commonly used software on these computers, including Matlab, e-prime, and of software that drives peripherals (e.g. eye tracker). He is not responsible, however, for other equipment or peripherals at the scanner (e.g. head coils). If the fMRI technologist on duty cannot troubleshoot the latter equipment, he/she may contact appropriate Phillips personel. Pat is available to trouble-shoot any of the hardware and software issues mentioned above. He can be reached either via telephone (office: 322-4584), pager (831-4602) or e-mail. Pat’s office in Wilson Hall is at 529WH. In addition, to better serve the fMRI community, Pat will also have a second office at the computer lab of the Vanderbilt University Institute of Imaging Science (VUIIS), adjacent to the scanner suite (room B163). Please keep in mind that Pat may not be able to arrive immediately to solve problems, and that the problem may not be easily or quickly solvable. In the rare event when Pat is not available, you or the fMRI technologist may contact Ken Wilkens (ken.wilkens@vanderbilt.edu, phone: 2-4019), Senior VUIIS Engineer, who will try his best to help out.

Software Installation

In the past, we have had a policy that any users can install new software on the computers at the scanner, but only after making an announcement to the fMRI community. This policy has served us well, and we will therefore continue with it, but please remember to announce any software change to the fMRI community (using the fmri@list.vanderbilt.edu email list). It would be useful, however, if we could keep track of the location of the installation software, in case some programs need to be re-installed at short notice. Thus, if you have installed software on one of the console room computers, please contact Pat to let him know. Pat is also available to help in installation of fMRI-related software and hardware in individual labs, including the transfer, import, and reading of fMRI data. At this time, Pat is not able to teach individual laboratories how to use particular fMRI-related software (e.g. SPM, BV), or advise you in data-analysis issues. Similarly, please address problems regarding fMRI data integrity (e.g. spikes) to VUIIS members (e.g. Chris Gatenby, Ken Wilkens). If you are uncertain where to direct specific fMRI issues or requests, Pat will provide assistance in locating the appropriate resources.

Finally, in addition to his functions at the 3T MRI scanner, Pat also ensures proper functioning of the TMS system and optical imaging systems in Wilson Hall.
