Title:
超音波観測装置
Document Type and Number:
Japanese Patent JP4590293
Kind Code:
B2
Abstract:
An ultrasonic observation apparatus in which the frame rate can be made higher than that in a mechanical or conventional electronic scan method. The ultrasonic observation apparatus includes: an ultrasonic endoscope including ultrasonic transducers; a transmission aperture setting unit for setting ultrasonic transducer groups as transmission apertures; a transmission frequency setting unit for setting respective frequencies of drive signal groups for the transmission apertures; a drive signal generating unit for generating the drive signal groups having the set frequencies; a reception aperture setting unit for setting ultrasonic transducer groups as reception apertures; a signal processing unit for performing signal processing on reception signal groups respectively outputted from the ultrasonic transducer groups; and a control unit for controlling the transmission aperture setting unit to sequentially change regions of the ultrasonic transducer groups to be set as the transmission apertures at a predetermined time interval.
