    摘要： A predetermined number of sectional planes are successively scanned, starting with a sectional plane in an initial position, by shifting a direction of X-ray emission from an X-ray emitting device. A reset operation is effected, after scanning the predetermined number of sectional planes, to switch the direction of X-ray emission to scan a sectional plane in the initial position. An examinee is moved synchronously with the reset operation to set a new sectional plane adjacent the predetermined number of sectional planes to the initial position. A predetermined number of sectional planes are successively scanned, starting with the new sectional plane in the initial position, by shifting the direction of X-ray emission from the X-ray emitting device. After scanning the predetermined number of sectional planes, a reset operation is effected and the examinee is moved to set a new sectional plane adjacent the predetermined number of sectional planes to the initial position. These operations are repeated until all sectional planes are scanned.

    摘要： Disclosed is a technology that prevents a part of a touch panel-equipped display displaying an ultrasonic tomographic image from getting dirty with a fingerprint or scratch when using a drag operation to change the content of the ultrasonic tomographic image displayed on the touch panel-equipped display. According to this technology, the display screen is divided into an ultrasonic image area A1 which displays an ultrasonic image P and an operating part display area A2 which displays buttons (Fov, Pos, ROI, and Dop) for selecting a change to be made in the ultrasonic image P. The operating part display area A2 has a touch panel, and when a finger F selectively touches one of the displayed buttons and is dragged, the displayed image P of the ultrasonic image area A1 is changed on the apparatus side according to the selected changes and drag direction.

    摘要： An omnidirectional camera having a camera for acquiring a digital image, an image data processing device for compressing a signal output from the camera and an external memory is disclosed. In the omnidirectional camera, a writing changeover unit accumulates signals output from a signal processing unit in one of a set of first internal memories until data is accumulated to a predetermined amount. When the data is accumulated to a predetermined amount, the writing changeover unit changes destinations and accumulates signals output from the signal processing unit in the other of the set of first internal memories. The signal is output to a data converting unit from the first internal memory where accumulation reaches the predetermined amount, and the data conversion unit compresses and converts an inputted signal to an image signal and the image signal is inputted to the external memory by an input/output control unit.
