  • Dual frequency band ultrasound transducer arrays
    Patent number: 7727156
    Abstract: Ultrasound probes that transmits/receives ultrasound pulses with frequencies both in a low frequency (LF) and a high frequency (HF) band, where the radiation surfaces of said HF and LF bands at least have a common region. Several solutions for transmission (and reception) of LF and HF pulses through the same radiation surface are given. The arrays and elements can be of a general type, for example linear phased or switched arrays, or annular arrays or elements with division in both azimuth and elevation direction, like a 1.5D, a 1.75D and a full 2D array. The LF and HF element division and array apertures can also be different.

  • Wide aperture array design with constrained outer probe dimension
    Patent number: 7300403
    Abstract: The invention presents solutions for large apertures of an ultrasound array under given dimension constraints given by the application for the ultrasound probe, for example by an endoluminal application. The invention has applications to annular arrays for 2D and 3D imaging, and also to linear or curvilinear arrays for 2D and 3D imaging. The invention further provides large aperture of arrays for dual frequency band operation with large difference between the dual bands.
