Abstract: There is provided an ultrasound system for forming strain images by decreasing decorrelation of receive signals, which vary with time or space. More specifically, the decorrelation between the receive signals obtained without and with applying stress to a target object is reduced to decrease an error, which occurs during the calculation of a delay. Also, a center frequency, which varies with depth of a target object, is compensated to form the strain image.

Abstract: A focusing method plays a big role of determining a resolution of an ultrasonic image. Focusing is performed by controlling an arrival difference of a signal up to a focal point by an electronics delay circuit. Here, the focusing method for focusing an ultrasonic signal having emitted to a focal point of an object via an array transducer including a plurality of elements, obtains an optimal focusing time delay curve according to the ultrasonic signal travelling velocity to thereby obtain an optimal ultrasonic image. Using only data obtained without any modification of the structure of an existing ultrasonic imaging system, a focusing time delay curve is estimated. Thus, a resolution can be enhanced with only a simple calculation.

Abstract: An apparatus and method capable of producing a tissue Doppler image without repeatedly transmitting ultrasound signals by the ensemble number to each scan line. An ultrasound beam is transmitted in a non-sequential manner and a plurality of receive beams received in response to each transmission of the transmit beam are grouped into an increment data group of a scan line index increasing direction and a decrement data group of a scan line index decreasing direction. Auto correlation is performed on the increment data group of the scan line index ascending order and decrement data group of the scan line index descending order, weights are applied to respective auto correlation values for the increment and decrement data group, and then the auto correlation values with the weight applied are summed to compute a mean phase. At least one of velocities, powers and variances in response to the mean phase is outputted to produce TDI.
