Latest Patents

Nakai's latest patents include a magnetic resonance imaging apparatus and processing method. This innovative apparatus is designed to display images that accurately represent the conditions of tissues, such as water and fat. The signal processing unit within the apparatus processes signals from each pixel of the first image generated based on an NMR signal. This processing generates a second image by preferentially selecting unprocessed pixels with high signal strength that are adjacent to already-processed pixels.

Another notable patent is focused on time-series image generation methods and programs. This invention aims to acquire more accurate tissue contrast images, such as water-fat separation images, during time-series imaging. It involves creating a static magnetic field non-uniformity map from multiple echo signals obtained in time series. The method includes processing to correct discontinuities in both spatial and time-series directions, ensuring high-quality imaging results.
