Abstract (en)
[origin: WO2009088307A1] Acoustic probes that transmits/receives acoustic pulses with frequencies both in a high frequency (HF), a and a selectable amount of lower frequency (LF1, LF2,..., LFn,...) bands, where the radiation surfaces of at least two of the multiple frequency bands have a common region. Several solutions for transmission (and reception) of HF, LF1, LF2,.... pulses and signals through the common radiation surface are given. The arrays and elements can be of a general type, for example annular arrays, phased or switched arrays, linear arrays with division in both azimuth and elevation direction, like a 1.5D, a 1.75D and a full 2D array, curved arrays, etc. The element division, array type, and array aperture sizes for the different bands can also be different. Electronic substrate layers with integrated electronic that connects to array elements can be stacked within the probe.
