Model for Imaging in MRI Using the Rotating RF Field

Figure 1

(a) Front and rear views of the actual RRFC system designed for head imaging, measuring approximately 340 mm in diameter and 480 mm in length, and showing custom-made air turbine , the inductively coupled RF link, and infrared (IR) photo-interrupter . The front view of the disassembled rotating cylinder shows the RF surface coil loop that is connected to a printed circuit board situated at the end of the rotating cylinder and is tuned by a variable capacitor network . (b) Schematic diagram of RRFC in side-view showing the major system components.
