Figure 4: Experimental setup for open 47.5mT scanner.

Figure 4:

A) The primary MR coil used for imaging (same spiral design as Fig. 2) tuned to 2.075 MHz with 20 KHz BW. B) EMI detector #1 is a tuned 10 turn RF pick up coil with diameter = 5cm. EMI detector #2 is an ECG electrode (not shown). C-D) The open 47.5mT low field scanner shown with subject and the two EMI detectors, including the electrode attached to subject’s wrist. Experiments were performed in 2 shielding configurations. C) The open shielding configuration included a copper box surrounding the head open on one side. D) The flexible shielding configuration included the addition of copper mesh, grounded to the copper box and draped over the subject.
