Systems and methods for ensuring coherence between multiple ultrasound transducer arrays

A system for maintaining coherence of ultrasound waves during a procedure, the system comprising:

• (a) a plurality of transducer arrays, each transducer array comprising a plurality of transducer elements;
• (b) a plurality of retention arms each for receiving one of the transducer arrays;
• (c) a connecting frame for receiving and mechanically retaining the arms in fixed, known angular relation to each other, wherein the connecting frame is configured to provide a finite series of allowed, angularly displaced mounting locations for the retention arms;
• and
• (d) a processor configured to:
• (i) determine relative locations of the plurality of transducer arrays with respect to one another and the connecting frame;
• (ii) determine a location of the connecting frame relative to an anatomic region of interest;
• (iii) thereafter, determine a spatial arrangement of the transducer elements in each transducer array with respect to the anatomic region of interest based on the relative locations of the transducer arrays and the location of the connecting frame relative to the anatomic region of interest;
• and
• (iv) based on the determined spatial arrangement of the transducer elements in each transducer array with respect to the anatomic region of interest, adjust a transmission configuration of the transducer elements in the plurality of transducer arrays to achieve a desired focusing property with respect to the anatomic region of interest while maintaining coherence therebetween.
