Definitions
- an ultrasonic imaging apparatus including a front end for transmitting and receiving an ultrasonic wave using a transducer and a host PC electrically connected to the front end, the same operation when operating in Live Mode Generates a real-time ultrasound image based on the RF data obtained by transmitting ultrasound pulses to the object in phase, and when operating in the cine reproduction mode or the image reconstruction mode, non-real-time ultrasound based on the obtained RF data Ultrasonic waves, characterized in that to generate an image, and to use the harmonic components to generate the real-time or non-real-time ultrasound image to adjust the phase between successive frame data, and extract the harmonic components through a method of synthesizing the continuous frame data It provides an imaging device.
- the synthesis process of the harmonic extraction unit 136 will be described assuming that N is 3.
- the beamformer 134 focuses RF data having the same phase stored in the data storage unit 132 to generate three consecutive received focusing signals having the same phase (eg, O °).
- the phase controller 135 adjusts the phases of the received focus signals having the same phase to 0 °, 120 °, and 240 °, respectively, so as to have a phase difference of 120 °.
- the harmonic extractor 136 may extract harmonic components by adjusting a phase of RF data having a plurality of frequencies (M frequencies) in sequence.
- the sequence preferably means a group unit having M frequencies, but may be interpreted as a group unit in which the same phase difference is adjusted.
- a process of synthesizing the RF data having three frequencies of the harmonic extracting unit 136 will be described on the assumption that N is 2.
- the harmonic extracting unit 136 may determine the respective phases.
- Second harmonic components may be extracted by extracting and synthesizing RF data having the same frequency in a sequence.
