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.

Apparatus and method for creating tissue doppler image using synthetic image

An ultrasound diagnostic device includes a plurality of channels configured to receive data and a scan line data forming unit including a plurality of sub-scan line data forming groups and a data summing unit. The sub-scan line data forming group forms partial data of scan lines, and the data summing unit forms scan line data of the scan lines by summing the partial data. The sub-scan line data forming group includes a plurality of sub-scan line data forming units for forming the partial data of the scan lines by using the receiving data and providing a transmission path of the receiving data. First data lines transmit the receiving data between at least one of the sub-scan data forming unit and the channels, and second data lines transfer the receiving data between the sub-scan line data forming units.

Ultrasound diagnostic device and method for forming scan line data

An ultrasound system and method for forming ultrasound data corresponding to a receive scan line independent of a synthetic aperture. The ultrasound system includes the ultrasound data forming unit configured to: form scan line data corresponding to each of the receive scan lines by using data provided from the receive channels; form accumulated data by accumulating the scan line data corresponding to the receive scan lines of the same position; set a storing start position for storing the accumulated data based on the transmit synthesizing number; and store the accumulated data by shifting the storing start position by 1, thereby forming ultrasound data corresponding to each of the receive scan linen lines.

Ultrasound system and method for ultrasound data

The present invention relates to a method of removing an effect of side lobes in an ultrasound synthetic image. The method includes: a) setting a plurality of scan lines and defining sequential indices upon the scan lines; b) setting a transmit order of a transmit beam for the scan lines in a non-sequential manner in which increment and decrement of the indices of the scan lines are repeated; c) transmitting the transmit beam based on the set transmit order to obtain a plurality of receive beams in response to each transmission of the transmit beam; d) grouping the receive beams to an increment group corresponding to an increment direction of the numbers of the scan lines and a decrement group corresponding to a decrement direction of the numbers of the scan lines; e) performing an auto correlation upon the receive beams included in the respective increment group and the decrement group; and f) applying weights to the auto correlation results and summing the weight-applied auto correlation results to thereby remove an effect of side lobes.
