  • ULTRASOUND SYSTEM AND METHOD FOR CONTROLLING STEERING ANGLES OF SCAN LINES
    Publication number: 20080045837
    Abstract: An ultrasound system comprises: a probe having a transducer array of n transducer elements for transmitting ultrasound signals, said n transducer elements being associated with respective scan lines; a steering angle calculating unit for calculating steering angles of the scan lines by using series determined by a relation between the steering angles of at least two scan lines; and a control unit for controlling transmission of the ultrasound signals such that the ultrasound signals can be focused along the scan lines based on the calculated steering angles of the scan lines.

  • ULTRASOUND DIAGNOSTIC SYSTEM AND METHOD FOR ADJUSTING OUTPUT OF DIGITAL SIGNALS
    Publication number: 20080009740
    Abstract: There is provided an ultrasound system, which includes: a probe for providing electrical analog signals in response to ultrasound signals reflected from a target object; an analog-to-digital converter for converting the electrical analog signals to digital signals; and a beam former for extracting a part of digital signals at a rate of n times of a center frequency of the electrical analog signals to form a receive beam, wherein n is a positive integer.

  • ULTRASOUND DIAGNOSTIC SYSTEM AND METHOD FOR FORMING MULTIPLE RECEIVING SCAN LINES
    Publication number: 20080009725
    Abstract: Embodiments of the present invention may provide an ultrasound imaging system and method for forming multiple receiving scan lines from one original receiving scan line. Ultrasound signals reflected from one original receiving scan line are converted into analog signals having a center frequency. The analog signals are converted into digital data. The digital data are coarsely delayed, wherein the coarsely delayed data are extracted at a rate of n-times of the center frequency. Data of the multiple receiving scan lines are formed by performing fine delay and interpolation. For the interpolation, parts of the extracted data are selected at a rate of n-times of the center frequency and the multiple receiving scan lines.

  • ULTRASOUND DIAGNOSTIC SYSTEM AND METHOD FOR FORMING IQ DATA WITHOUT QUADRATURE DEMODULATOR
    Publication number: 20080009726
    Abstract: An ultrasound diagnostic system and a method for forming IQ data without a quadrature demodulator are disclosed. Ultrasound echoes from a target object are converted into analog signals, which have a center frequency. The analog signals are converted into digital signals and parts of the digital signals are extracted at a rate of n-times of the center frequency, wherein “n” is a positive integer. Focused-receiving signals are formed with the extracted digital signals and IQ data are obtained by selecting at least one pair of the focused-receiving signals. The focused-receiving signals in each pair have a phase difference of ?/4 with respect to each other, where “?” is a wavelength determined with the center frequency.
