Latest Patents

One of his latest patents is a method for correcting magnetic field inhomogeneity in MRI. This method addresses issues caused by factors such as implanted metal and air/tissue interfaces. It corrects geometric distortion in a static magnetic field by adding a compensation gradient. This gradient is applied in the slice selection direction and has a timing that aligns with the standard frequency encoding gradient. Additionally, it utilizes an RF coil that is sufficiently large to minimize the impact of metal implants. The method also includes acquiring two images with complementary slice thickness errors to cancel out the effects of local signal loss due to magnetic field inhomogeneity. Another significant patent involves water-fat imaging with direct phase encoding, which allows for the acquisition of complex images to produce separate images of water and fat components.
