Abstract:
PURPOSE: An ultrasonic image generation device and a method thereof are provided to selectively use an ultrasonic signal by request of a user, thereby improving device performance. CONSTITUTION: An ultrasonic image generation device (100) comprises an ultrasonic transducer and a pulse generation unit (110). The ultrasound transducer has a broadband frequency transfer characteristic and an ultra-wide band frequency transfer characteristic. The pulse generation unit (110) is provided within the frequency band of the ultrasonic transducer, and generates multiple ultrasonic pulses which have a different center frequency from each other.

Abstract:
PURPOSE: A device and a method for performing analog beamforming are provided to reduce a memory, the operation quantity of a system, and the number of hardware devices for transmitting ultrasonic signals. CONSTITUTION: A device for performing analog beamforming comprises a delay control part(707) outputting first control information showing delay times of first unit time and second control information showing delay times of second unit time about an ultrasonic signal at a position within a predetermined scan area; a first analog device which delays or passes a received ultrasonic signal based on the first delay control information for the first unit time; a second analog device which delays or passes an ultrasonic signal which is delayed or is passed based on the second delay control information for the second unit time; and a combiner(704) adding up ultrasonic signals postponed by the second analog device.

Abstract:
PURPOSE: A two dimensional transducer-array driving apparatus is provided to shorten loading time by controlling driving parts using the control information of delay time and a receiving transducer. CONSTITUTION: Multiple driving parts(110) drive each transducer included in a two dimensional transducer-array. A drive control part(120) controls the multiple driving parts. Each of the multiple driving parts comprises a register, a comparator, a pulse frequency setting part, a multi pulse controlling part, a transmitting signal production part, a signal transmitting and receiving part, a transmitting and receiving switch, and a receiving signal amplifier. A memory stores the control information of the delay time and the receiving transducer. A transmit-receive switch(1127) turns on and off by referring to the control information of the receiving transducer outputted from the register.
