Description

  The present invention relates to a medical image system, an interpretation order generation apparatus, and a program.

  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). Along with this, the target of image diagnosis by a doctor has shifted from an image output on a film to an image displayed on a monitor.

  By the way, with the increase in the types of photographing devices and higher-resolution images being obtained, technological advancements have demanded more specialized expertise in doctor diagnosis. In addition, since the amount of images to be taken is increasing, it is difficult for a clinician to make an image diagnosis while facing a patient. Therefore, in a large-scale hospital, a doctor who specializes in interpretation (an interpretation doctor) diagnoses an image, creates an interpretation report (report), and a clinician often diagnoses a disease name based on the result. When notifying the interpretation doctor to the interpretation target, it is necessary to send a paper slip or send the interpretation order to a report system that creates an interpretation report through an electronic medical record or an ordering system at the time of imaging.

For example, the RIS issues an interpretation order, the interpretation report server stores the interpretation order, the interpretation report creation device is in progress of the interpretation report creation (unread interpretation, interpretation in progress, already interpretation), and examination is awaiting definitive diagnosis A technique for displaying whether or not a state is present has been proposed (see Patent Document 1).
