An apparatus and method of imaging an imaging region (7) employ an acoustic transducer array (10′) to produce image data for the imaging region (7), wherein there are one or more obstructions (15-1, 15-2, 15-3) between the acoustic transducer array (10′) and at least a portion (5) of the imaging region (7). One or more processors exploit redundancy in transmit/receive pair paths among the acoustic transducers in the acoustic transducer array (10′) to compensate for missing image data of the imaging region (7) due to the one or more obstructions (15-1, 15-2, 15-3), and produce an image of the imaging region (7) from the compensated image data.
