  • Publication number: 20220413079
    Abstract: Distortion generated in an image is effectively corrected in imaging using an EPI sequence such as DWI without extending an imaging time. After one excitation RF pulse of EPI is applied, a navigator scan in which the polarity of the phase encoding is opposite to that of the main scan is performed continuously to the main scan, and the distortion of the image by using the navigator scan data obtained by the navigator scan is corrected. In a case of multi-shot, phase information obtained from the navigator scan data for each shot is used to perform phase correction and multi-shot reconstruction on the main scan data of each shot.

  • Publication number: 20220361769
    Abstract: A load measurement device includes an acquisition unit, a first extraction unit, a second extraction unit, and an output unit. The acquisition unit acquires measurement information output from a load distribution sensor that detects a load distribution received from a sole of a subject. The first extraction unit extracts a region having a load value equal to or larger than a first threshold value as a first region based on the measurement information, and detects the first region as a sole region. The second extraction unit extracts a second region having a load value equal to or larger than a second threshold value that is smaller than the first threshold value from a re-extraction target region defined with the first region as a reference, and adds the second region to the sole region. The output unit outputs information related to a load distribution of the sole region.
