  • Patent number: 8965072
    Abstract: A storage unit stores data of a plurality of previous images of a plurality of regions generated during a previous catheter procedure. A route map generating unit arranges a plurality of first catheter images or blood vessel images included in the plurality of previous images according to the positional relationship between the plurality of regions to generate a route map indicating the distribution of the plurality of first catheter images or blood vessel images. A specifying unit specifies a specific portion of a second catheter image included in a current image generated during a current catheter procedure. A calculating unit calculates the position of the specified specific portion on the route map on the basis of the positional relationship between the current image and the previous image. A display unit displays a specific previous image corresponding to the calculated position.

  • Patent number: 4781977
    Abstract: A cyclodextrin adsorbing material composed of a water-insoluble resin substrate to which a ligand having such a size as to be included by cyclodextrin is chemically bonded via a spacer radical; a method of separating and purifying cyclodextrin from an aqueous solution containing it, which comprises bringing said aqueous solution into contact with the above adsorbing material to adsorb cyclodextrin on the adsorbing material, and subjecting the adsorbing material to a desorption treatment to recover cyclodextrin; and a method of increasing the amount of cyclodextrin yielded, which comprises carrying out a cyclodextrin-forming reaction by an enzymatic method in the presence of the above adsorbent material.
