  • Patent number: 5471988
    Abstract: Provided on the side of a distal end of an insertion part are an observation ultrasonic transducer for acquiring an ultrasonic image and a therapeutic ultrasonic transducer for outputting a therapeutic ultrasonic wave so as to be focused. Positioning or the like between the observation ultrasonic transducer and the therapeutic ultrasonic transducer is so conducted that a focusing point at which the therapeutic ultrasonic wave is focused is locked to a predetermined position within a scanning range of the observation ultrasonic wave. If the position of the focusing point is locked whereby a lesion part to be treated is set to a predetermined position on an ultrasonic image, it is necessarily possible to conduct the position setting to the focusing point. It is also made possible to confirm the position of the lesion part and to acoustically observe a state of the lesion part during irradiation of the therapeutic ultrasonic wave.

  • Patent number: 5279301
    Abstract: An ultrasonic image analyzing apparatus determines, on the basis of ultrasonic tomographic image information on a body portion being inspected, the properties of the tissues of the inspected portion, and causes a lesion portion to be displayed on a color image screen or the like, thereby allowing a diagnosis. The apparatus enables appropriate parameters for image analysis which correspond to the object organ, a body mark, and the type of ultrasonic probe used, to be automatically set. The apparatus also enables the size, the shape, the manner of scanning, etc. of regions of interest (ROIs), which are provided on the image of the portion being observed for the purpose of calculating the parameters, to be set in correspondence with the directions in which the ultrasonic wave from the probe propagates. Accordingly, the apparatus makes it possible to perform optimal image analysis with respect to the observation-object portion, and hence, perform correct diagnosis.
