Wide aperture array design with constrained outer probe dimension

摘要

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.
