Classification: CPC A  G | IPC A  G

Claim 4:
5. An ultrasound apparatus comprising:
two or more separate ultrasound transmitters positioned to transmit a signal into a coincident region,
a receiving array for receiving a wavefront representative of a transmitted signal from each of the two or more separate ultrasound transmitters after interaction of the transmitted signal with a medium located within the coincident region;
location processing logic to:
select one or more parameters which together act to define a relative location of each of the two or more separate ultrasound transmitters in space;
analyze each of the received wavefronts to make an initial guess at the selected one or more parameters;
perform an iterative process to refine the initial guess at the selected one or more parameters, the iterative process operating to refine the initial guess by increasing a correlation between the received wavefronts; and
determine a relative spatial position of each of the two or more separate ultrasound transmitters; and

signal combination logic to use the determined relative spatial position of each of the two or more separate ultrasound transmitters to perform coherent signal combination of the received wavefronts received at the receiving array from each of the two or more separate ultrasound transmitters after interaction of the transmitted signal with the medium located within the coincident region.
