Fig. 2.

(a) A representation of the pressure field of a single element transducer with a central rotation 0° (green) and central rotation ${\theta }_{c,n}$ (blue). (b) The area between C1 and C2 stays in the FOV of all the tilted transducers, and the thickness of this area is $2R_S$. (c) Each area ($A_n$) stays in the FOV of the tilted transducers with a central rotation of ${\theta }_{c,n}$.
