Patent number: 10048343Abstract: It is an object of the present invention to provide a technique for reducing the degradation of the image quality due to the phase difference between scanning trajectories (blades) in measurement using a non-orthogonal sampling method. Therefore, in the present invention, correction for reducing the phase difference between a plurality of scanning trajectories (blades) measured by using a non-orthogonal sampling method is performed at the time of image reconstruction. For example, the reduction of the phase difference is performed using a method of matching the phases at the intersections between blades, matching the phases of all blades at positions determined by considering the shift amount in the frequency direction, or canceling out the phase change amount of each blade obtained by calculation.Type: GrantFiled: May 8, 2014Date of Patent: August 14, 2018Assignee: HITACHI, LTD.Inventors: Miyuki Takahashi, Hikaru Hanada

Patent number: 10031205Abstract: The present invention obtains high-quality images even in a case of measurement with a radial sampling method. For this purpose, pre-measurement is performed to extract only a component different for each blade from among shift amounts from among echo signals, and a shift amount in k-space of an echo signal by the said component is reflected to a reconstruction process. In the pre-measurement, echo signals are obtained respectively by applying readout gradient magnetic field pulses that change the polarity to the positive and negative and that have the same pulse shape as readout gradient magnetic field pulses to be used in an image acquisition sequence. A shift amount is obtained for each axis of X, Y, and Z of an MRI apparatus as a variation amount of a phase difference between both the echo signals.Type: GrantFiled: August 20, 2014Date of Patent: July 24, 2018Assignee: HITACHI, LTD.Inventors: Hikaru Hanada, Miyuki Takahashi, Kuniharu Oka, Masahiro Takizawa
