Directions

Map

The MRI facility is located in the Cancer Research Institute building at 15 O'Kill Street (Google Maps). O'Kill St runs between Barrie St and George St, parallel to and in between Stuart St and King St W.

To find the MRI facility, go to the south end of the Cancer Research Institute (CRI) building, at 15 O'Kill Street. There is a small parking lot between O'Kill street and the CRI building, and from the street the entrance is not clearly visible because it is in small stairwell.

Once you are at the entrance you will see a sign for the MRI Facility on the wall to the left, and below the sign is a call button. Press the call button to have  someone come and open the door to let you in.

Hours of operation

Monday – Friday* +: 09:00 – 17:00

*The hour lunch-break for the technologist is scheduled between 11AM and 1PM to allow flexibility in study start/end times and maximum scheduling, but is usually from 12-1PM. Any change from 12-1PM will be indicated on the facility calendar and must be done with prior arrangement.

+There may be Maintenance or Facility time listed on the schedule. Scanning is not possible during those times. Time for study setup within the control room may be possible during Maintenance Time – contact the technologist to find out.

Scheduling

Please contact the MR Manager at briend@queensu.ca to schedule your time.

In order to maximize the facility schedule users are encouraged to use the following start times for studies whenever possible:

  • 9:00 - 1.5 hour booking
  • 10:30 - 1.5 hour booking
  • 13:00 - 2 hour booking
  • 15:00 - 1.5 hour booking

Shorter or longer time slots may be booked, preferably starting at one of these 4 start times, to allow other users to book studies before or after.

NOTE: 72 hours notice is required to cancel studies without being charged for the time booked.

Fees

All rates are predetermined by the Facility Management Committee (FMC) and are subject to periodic review. The current rates are as follow:

Rates for members of the CNS (effective May 1st 2024):

  • Research Study rate $500/hr – operator assisted

Additional information on rates is available on SOP #13 Systems Billing Guide and Standard Rates (PDF 956.4 KB)

Standard Operating Procedures

To obtain approval to access the facility all users must attend an MR Safety Training session, read all Facility SOPs and sign the SOP Compliance Statement, and complete a Safety Checklist.

Equipment

A variety of equipment is available for use in MRI Experiments.  Please contact the MR Manager for more details or if you have any other questions.

We provide a state-of-the-art computer system with high performance processors and video cards from Nvidia (GTX 1660 and better), internet connection, high-quality sound card, and connected to the projector and button response box. Matlab and E-Prime are installed for running fMRI studies. Windows and Linux operating systems are available.

If you would like to run from your own laptop, connections are available for connecting the visual display and button response to your laptop via a switchbox.

The PROPixx is a unique DLP LED projector which has been designed to be the most flexible display possible for vision research. The PROPixx features a native resolution of 1920 x 1080, and can be driven with refresh rates up to 500 Hz in RGB mode (1440 Hz greyscale) with deterministic timing.  The projector displays images on a rear projection screen that hangs in the bore.

MRI-compatible audio devices and corresponding ear plugs to allow the delivery of high fidelity audio input to a participant in a MRI environment.  The Sensimetrics system is a well-established standard in the field of fMRI sound research and the choice of many MRI research facilities around the world. This high-quality audio device is required to allow the manipulation of sounds in the full spectrum of human hearing.  Some MRI parameter conditions do apply with this system.

Monitoring and recording of peripheral pulse (top), ECG (middle) and respiration (bottom) through Siemens wireless physiological equipment.

These devices allow for the recording of the most common biometric signals at extremely high fidelity. These signals include ECG (electrocardiogram), GSR (galvanic skin response), heart rate, respiration, end-tidal CO2, Blood Pressure, and accelerations.  We have a complementary system available for our mock scanner.
