Title: Innovations of Robert J Perlmutter
Introduction
Robert J Perlmutter is a notable inventor based in Palo Alto, California. He has made significant contributions to the field of magnetic resonance imaging (MRI) with a total of three patents to his name. His work focuses on enhancing the functionality and accuracy of MRI technology, particularly in challenging environments.
Latest Patents
One of his latest patents is for an MRI apparatus with external magnetic field compensation. This innovation addresses the challenges posed by magnetically noisy environments, such as those created by nearby subway trains. The apparatus utilizes a magnetometer type sensor to detect external field fluctuations. After adjusting for the filtering effects of the MRI device's magnet structure, the master oscillator is modified to compensate for these fluctuations. Alternatively, the current of the magnet coil can be adjusted to achieve the same effect.
Another significant patent by Perlmutter is related to an improved image restoration process for magnetic resonance imaging. This technique enhances the accuracy of image points by employing an advanced interpolation method that utilizes surrounding pixels. The interpolation technique ensures a uniform noise variance through a weighted average approach, while also maintaining the sum of the squares of the interpolation weighting functions at a constant. Additionally, the resulting images can be sharpened using a hybrid convolution technique that processes border regions separately.
