Latest Patents

Masaaki Umeda's latest patents underscore his innovative approach to MRI technology. One significant patent details a magnetic resonance imaging apparatus that includes processing circuitry designed to optimize the acquisition of plural echo signals. This apparatus sets a pulse sequence that allows for the repeated application of a refocusing pulse post-excitation, facilitating data collection on multiple slices that are parallel to each other. The design enhances imaging by ensuring that the slice thickness for refocusing is greater than that for the excitation pulse while avoiding consecutive data collection on adjacent slices.

Another noteworthy invention by Umeda is the imaging parameter determining method employed in MRI technology. This method utilizes processing circuitry to determine essential parameters based on the application of inversion and flip pulses. Key variables, such as the intensity of the slice selecting gradient magnetic field, are precisely controlled to enhance the selection process, thereby improving the quality of the MRI scans.
