  • Publication number: 20250244433
    Abstract: Provided is a technique of minimizing an influence of TR extension due to a navigator echo for body motion detection without reducing a time resolution of body motion detection in imaging using the navigator echo. In a case in which imaging is performed in accordance with a predetermined pulse sequence by using an MRI apparatus, control of generating a navigator echo at a predetermined timing in the pulse sequence is performed, and control of making a timing at which the navigator echo is acquired different between a case in which a repetition time of the pulse sequence is equal to or greater than a preset threshold value and a case in which the repetition time is less than the threshold value is performed.

  • Publication number: 20250244432
    Abstract: Provided is a technique of improving accuracy of image reconstruction accompanied by body motion correction processing. In a case in which a period during which a body motion occurs is defined as a first period based on a result of detecting a body motion of an examination target disposed in a static magnetic field space, a second period that includes the first period and that is longer than the first period is specified. In measurement data of the examination target collected by magnetic resonance imaging, data collected in the second period is removed or corrected to generate an image of the examination target. As the second period, a detection timing error can be compensated for by extending a start end side of the first period, and data collected at a time at which a signal is unstable due to the body motion can be removed by extending a terminal end side.

  • Patent number: 12150747
    Abstract: Even when imaging is aborted, data collected so far is utilized in image reconstruction, thereby enhancing examination efficiency. A certain priority imaging data available for image reconstruction by a fast-imaging method is determined, when collecting k-space data according to a predetermined imaging method. If collection of the certain priority imaging data is completed when imaging is aborted, imaging reconstruction is executed using the priority imaging data. The priority imaging data is determined based on a relationship between the imaging method under execution, and the fast-imaging method underlying determination of the priority imaging data.

  • Publication number: 20210353906
    Abstract: This catheter includes an outer layer formed of a resin, and an inner member covered with the outer layer. The distal end of the inner member is located proximally of the distal end of the outer layer. The outer layer has a first region extending from the distal end of the outer layer to the distal end of the inner member, and a second region which is positioned proximally of the first region and covers the inner member. The resin which forms the second region of the outer layer has a lower hardness than the resin which forms the first region.
