  • Patent number: 10027872
    Abstract: The accessory apparatus includes an accessory communicator providing a notification channel, a first data communication channel and a second data communication channel. The accessory controller transmits, in response to receiving a transmission request from an image-capturing apparatus through the notification channel, accessory data to the image-capturing apparatus through the first data communication channel and receives camera data transmitted from the image-capturing apparatus through the second data communication channel. The accessory controller has a function of detecting a camera communication error in the camera data and is configured to, when detecting the camera communication error, transmit accessory error information to the image-capturing apparatus and erase the accessory data stored in an accessory data buffer.

  • Publication number: 20180192996
    Abstract: An ultrasonic diagnostic device includes an ultrasonic probe and processing circuitry. The probe conducts ultrasonic scanning on a three-dimensional area of a subject and receives a reflected wave from the subject. The circuitry acquires the correspondence relation between a position in ultrasonic image data on the three-dimensional area based on the reflected wave and a position in volume data on the subject captured by a different medical-image diagnostic device. The circuitry receives, from an operator, an operation to set a position marker, which indicates the position at which blood-flow information is extracted, on a scan area of the ultrasonic image data. The circuitry causes the image generated during a rendering process on the ultrasonic image data to be displayed and causes the position marker to be displayed at a corresponding position on a display image based on at least the volume data in accordance with the correspondence relation.
