Title: The Innovations of Gerrit H Van Yperen
Introduction
Gerrit H Van Yperen is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of magnetic resonance imaging, holding a total of eight patents. His work has advanced the technology used in medical imaging, providing better diagnostic tools for healthcare professionals.
Latest Patents
One of his latest patents is titled "Magnetic resonance method and device." This invention relates to a method for imaging diffusion parameters of a body using magnetic resonance. The method involves an adjustment pulse sequence and an imaging pulse sequence. The adjustment pulse sequence measures preparation MR signals, while the imaging pulse sequence measures position-dependent MR signals. The imaging pulse sequence is adjusted based on information from the preparation MR signals measured during the adjustment pulse sequence.
Another significant patent is "Eddy current compensation in magnetic resonance imaging." In this invention, an MRI device operating according to a spin-echo method applies switched gradient magnetic fields in the form of slice selection, phase encoding, and read gradients. The switching of these gradients causes eddy currents in metal parts of the apparatus, which can disturb the applied magnetic fields. This invention compensates for the disturbing effects of the eddy currents by supplementing a sequence of switched gradient magnetic fields with additional gradient fields. These additional fields have a zero net effect but induce further eddy currents that compensate for the disturbances caused by the regular switched gradient magnetic fields.
