The antenna extends from -10 to 10 cm horizontally, in the center of the plot. An illustration of a preliminary design of the catheter antenna. The portion from the tip to the electronic circuitry is inserted into blood vessels. Figure 10 MR images of a perforated cardboard in tap water. Figure 11 SNR versus radial distance, a comparison between theory and experiment at 1.5 Tesla.
Radial distance is in millimeters.
A 1cm 1cm portion of the image is shown. Figure 13 Large FOV rabbit image, taken with the catheter antenna, without sensitivity correction. To allow for peripherals be seen, the brightness around the catheter antenna is saturated. The dark path in the center corresponds to the aorta.
