Patent number: 7903854Abstract: Volume data formed of tomographic images (medical images) is stored in a storage unit of a data center. Recorded in a tag area of each tomographic image is site information indicating the site contained in each tomographic image. A data server of the data center reads the volume data from the storage unit in response to a transmission request from a medical facility. Then, the data server extracts from the volume data the tomographic images of the same site as designated by the transmission request. The data server transmits the extracted tomographic images to the medical facility which made the transmission request.Type: GrantFiled: August 6, 2007Date of Patent: March 8, 2011Assignee: FUJIFILM CorporationInventors: Hideyuki Sakaida, Shinichi Takeyama, Takuma Sakamoto

Publication number: 20090245609Abstract: An image server has a medical image DB for storing plural medical images, an anatomical illustration DB for storing plural anatomical illustrations that are used for comparison with the medical images, and an attribute information DB. In the attribute information DB, a file name of each anatomical illustration and a site depicted in each anatomical illustration are associated with each other. Upon receipt of a transfer request of anatomical illustration from a client terminal, a CPU of the image server reads out a medical image corresponding to the file name included in the transfer request from the medical image DB. The CPU inputs the read out medical image to a site recognizing section and to recognize the site being shot. The CPU then reads out an anatomical image corresponding to the site recognized by the site recognizing section from the anatomical illustration DB and transfers it to the client terminal.Type: ApplicationFiled: September 20, 2007Publication date: October 1, 2009Applicant: FUJIFLIM CORPORATIONInventors: Hideyuki Sakaida, Takuma Sakamoto

Publication number: 20080235395Abstract: A medical image transfer system consists of a plurality of transfer servers for transferring individually a medical image from a modality to an image server, and a control server for controlling the transfer servers. The transfer server sends information tagged to the medical image to the control server, to inquire about a destination of the medical image and an editorial process to be executed on the tagged information to adapt it to the destination. The control sever determines one of the image servers as the destination on the basis of the tagged information as received from the transfer server, and notifies of the destination and the editorial process necessary for the destination as a response to the inquiry. The transfer server executes the assigned editorial process on the tagged information and then transfers the medical image with the processed tagged information to the assigned destination.Type: ApplicationFiled: March 13, 2008Publication date: September 25, 2008Applicant: FUJIFILM CORPORATIONInventor: Takuma SAKAMOTO
