Abstract:
1. An intraluminal MRI probe comprising: a. a first rectangular dielectric sandwich comprising two opposing long sides, two opposing short sides, a dielectric substrate having a thickness in the range of 1-3000 microns, a dielectric constant in the range of 1-1000, a first surface having a surface area in the range of 0.5-10,000 square millimeters, and a second surface having a surface area in the range of 0.5-10,000 square millimeters, a first conducting layer deposited on said first surface, and a second conducting layer deposited on said second surface; a second rectangular dielectric sandwich positioned to face said first sandwich and comprising two opposing long sides, two opposing short sides, a dielectric substrate having a thickness in the range of 1-3000 microns, a dielectric constant in the range of 1-1,000, a first surface having a surface area in the range of 0.5-10,000 square millimeters, and a second surface having a surface area in the range of 0.5-10,000 square millimeters, a first conducting layer deposited on said first surface, a first conducting layer deposited on said first surface, and a second conducting layer deposited on said second surface; b. a third rectangular dielectric sandwich comprising two opposing long sides, two opposing short sides, a dielectric substrate having a thickness in the range of 1-3000 microns, a dielectric constant in the range of 1-1,000, a first surface having a surface area in the range of 0.5-10,000 square millimeters, and a second surface having a surface area in the range of 0.5-10,000 square millimeters, a first conducting layer deposited on said first surface, a first conducting layer deposited on said first surface, and a second conducting layer deposited on said second surface, said third rectangular dielectric sandwich positioned such that one of its long sides is contiguous with a long side of said first sandwich and the other of its long sides is contiguous with a long side of said second sandwich; and c. a fourth rectangular dielectric sandwich comprising two opposing long sides, two opposing short sides, a dielectric substrate having a thickness in the range of 1-3000 microns, a dielectric constant in the range of 1-1,000, a first surface having a surface area in the range of 0.5-10,000 square millimeters, and a second surface having a surface area in the range of 0.5-10,000 square millimeters, a first conducting layer deposited on said first surface, a first conducting layer deposited on said first surface, and a second conducting layer deposited on said second surface, said fourth rectangular dielectric sandwich positioned to face said third sandwich such that one of the fourth sandwich's long sides is contiguous with a long side of said first sandwich and the other of its long sides is contiguous with a long side of said second sandwich and further such that the four sandwiches define a rectangular solid internal volume and the first conducting layer of each sandwich faces said internal volume.
