  • Publication number: 20240136062
    Abstract: [Problems] Provision of a system for assisting diagnosis/treatment of stroke which can easily provide supportive information so that the type of stroke can be determined appropriately and corresponding treatment strategy can be implemented. [Solutions] When the device for assisting diagnosis/treatment of stroke 101 acquires information of CT images, DWI, ADCmap, and MRA images indicating state of stroke from the device for providing information about state of stroke 103, it uses the acquired information of images and the information about laboratory findings to determine the type of stroke in a unit of stroke type determiner trained to use the predetermined information of images and the predetermined information about laboratory findings to determine the type of stroke corresponding thereto.
