  • Patent number: 7261694
    Abstract: An ultrasound system and method for calculation and display of tissue deformation parameters are disclosed. The tissue deformation parameter strain is determined by an accumulation of strain rate estimates for consecutive frames over an interval. The interval may be a triggered interval generated by, for example, an R-wave in an ECG trace. Three quantitative tissue deformation parameters, such as tissue velocity, tissue velocity integrals, strain rate and/or strain, may be presented as functions of time and/or spatial position for applications such as stress echo. For example, strain rate or strain values for three different stress levels may be plotted together with respect to time over a cardiac cycle. Parameters which are derived from strain rate or strain velocity, such as peak systolic wall thickening percentage, may be plotted with respect to various stress levels.

  • Patent number: 7261693
    Abstract: A soft tissue diagnostic apparatus for diagnosis of stress and injury in anatomical soft tissue by detecting the response of the soft tissue to acoustic energy and a method of detecting soft tissue damage or stress and treating the tissue. An acoustic transmitter transmits excitation acoustic energy toward a target area of soft tissue of a subject. An acoustic receiver receives responsive acoustic energy generated by the soft tissue in response to the excitation acoustic energy transmitted by the acoustic transmitter and generates an output signal representative of the response of the soft tissue to the excitation acoustic energy. An analyzer receives the output signal of the acoustic receiver and provides an indication of at least one of stress and injury in the soft tissue based on the output signal. Areas of stress are inhibited to find the origin of soft tissue pain.

  • Patent number: 7238157
    Abstract: Methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.

  • Patent number: 7226416
    Abstract: Ultrasonic imaging utilizing multiple sets of transmit pulses differing in amplitude, frequency, phase, and/or pulse width is disclosed. One embodiment has phase differences between the k transmit signal as 360 k ? ? d ? ? e ? ? g ? ? r ? ? e ? ? e ? ? s providing for constructive interference of the kth order harmonic pulse, while an amplitude modulation of each transmit profile is constant between sets. These sets of pulses are transmitted into media of interest and received echoes from these pulses are combined to form art averaged signal. The averaged pulses represent the net common mode signal received from each of the transmit sets. This combined signal set is used to reconstruct an ultrasound image based on broad beam reconstruction methodology.
