Latest Patents

Wiesler holds a patent for a method titled "Local magnetization spoiling using a gradient insert for reducing the field of view in magnetic resonance imaging." This invention involves a method and related apparatus for suppressing the magnetic resonance signal to an experimentally adjustable depth. By applying a spatially inhomogeneous field between the slice-select pulse and the data acquisition, the signal from near surface regions can be eliminated. This allows for a reduction in the field of view of an image without introducing aliasing artifacts, thereby improving the image's resolution or decreasing imaging time. Experimental tests on a phantom and a human subject indicate that the depth of signal suppression may be continuously varied to depths of over 80 millimeters with modest requirements on power supplies, pulse sequences, and materials.
