A multifunctional probe includes a hand-held housing, a signal detector and an array probe. The signal detector is flexibly disposed on the hand-held housing or at its first end. The array probe is disposed at one end (e.g., second end) of the hand-held housing and electrically coupled to the signal detector. The first contact time of the signal detector in contact with the living body may at least partially overlap with the second contact time of the array probe in contact with the living body. The signal detector and the array probe generate the first electronic signal. The multifunctional probe includes a flexibly-connected signal detector and an array probe, which can contact and/or detect the living body at the same time. Thus, the detection efficiency and accuracy are effectively increased. A detection method applied to the multifunctional probe is also provided.

The present invention related to an ultrasound imaging system win which the scan head includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When using a hierarchical two-stage or three-stage beamforming system, three dimensional ultrasound images can be generated in real-time. The invention further relates to flexible printed circuit boards in the probe head. The invention furthermore related to the use of coded or spread spectrum signaling in ultrasound imagining systems. Matched filters based on pulse compression using Golay code pairs improve the signal-to-noise ratio thus enabling third harmonic imaging with suppressed sidelobes. The system is suitable for 3D full volume cardiac imaging.
