Begin by using a 3T MRI scanner equipped with multi-channel receiver head coils for functional magnetic resonance imaging. Use the posterior half to ensure a larger viewing angle without obstruction. Next, set up a T1 weighted MPRAGE sequence by inputting a repetition time of 2.2 seconds and a field of view of 176 by 256 by 208 millimeters.
Provide a spatial resolution of 1 by 1 by 1 millimeter. Bandwidth of 190 hertz per pixel. Flip angle of 13 degrees.
And a scan duration of 3.1 minutes. Set up a gradient echo EPI sequence with a repetition time of 2 seconds, echo time of 30 milliseconds, field of view of 220 by 220 millimeters, in-plane resolution of 1.7 by 1.7 millimeters with 29 slices of 3 millimeters thickness, and a bandwidth of about 1500 hertz per pixel. Now, measure the dimensions of the head coil and scanner bore.
Then, connect the PVC tubes with PVC elbows to construct a simple PVC pipe frame, and with nylon screws, attach the ends of the plastic rod holding the mirror to the frame. Note that the mirror is attached to the plastic rod with plastic screws. Make sure that the screws are loose enough for the mirror to be manually rotated to an optimum angle.
After screwing a segmented rear projection screen to a frame, place the screen inside the back of the scanner, positioning it behind the head coil to maximize the field of view.
