Description

  The present invention relates to a medical image system, and more particularly to a medical image system that uses a medical image stored in a portable storage medium.

  In recent years, in the medical field, digitization of medical images taken of patients has been realized. For example, a medical image captured and digitized by an image generation apparatus (modality) such as a CR (Computed Radiography) apparatus, a CT (Computed Tomography) apparatus, or an MRI (Magnetic Resonance Imaging) apparatus is used together with patient information and examination information. It is stored and managed in PACS (Picture Archiving and Communication System).

  Specifically, imaging order information including patient information and examination information is sent to the modality from HIS (Hospital Information System) and RIS (Radiological Information System), and the modality is operated by the imaging engineer. According to the shooting order information. A medical image obtained by the imaging is generated in a data format based on the DICOM (Digital Imaging and Communications in Medicine) standard, and then transferred to the PACS. In HIS and RIS, medical images stored in the PACS can be referred to based on patient information and examination information.

  When a patient uses a plurality of medical institutions, it is convenient that medical information of the same patient can be exchanged between the plurality of medical institutions. As such an example, in a medical institution cooperation system in which a plurality of medical institutions are configured to be able to transmit and receive data via the Internet, it has been proposed to exchange information on medical information and the like by e-mail (Patent Document 1). reference).

Also, as a method of providing medical images managed by PACS to other systems and general patients, a portable type compatible with PDI (Portable Data for Imaging) in IHE (Integrating the Healthcare Enterprise), apart from the provision by the network Provision by a storage medium is also performed. In this method, medical images are stored in a storage medium such as a CD-R (Compact Disk Recordable) or a DVD-R (Digital Versatile Disk Recordable), and data is transferred by transporting the storage medium. The PDI also defines a directory structure and index files in a storage medium, and data exchange between different medical institutions is guaranteed.
