  • Publication number: 20100099988
    Abstract: An ultrasound diagnosis apparatus that can perform predetermined input operations without using an operation table or a remote controller. To realize improved ergonomics in an ultrasound diagnosis apparatus, predetermined input operations, such as storing moving images or change of scanning mode, can be performed during examinations analyzing physical operations of an ultrasound probe from generated images. An image data analyzing unit acquires movement data of an ultrasound probe by analyzing image data generated by processing the received signals from the ultrasound probe. An operation converting unit converts the acquired movement data to a predetermined input operation data. A system control unit controls each of units in the ultrasound diagnosis apparatus based on the input operation data from the operation converting unit.
