Assignee: KING'S COLLEGE LONDON
Field: Measurement (Instruments)
Classification: CPC A  G | IPC A  G

Claim 11:
12. A non-transitory computer readable storage medium storing instructions thereon that, when executed by at least one processor, cause a computer device to:
provide, from each of two or more separate ultrasound transmitters, a signal into a coincident region;
receive, at a receiving array, wavefronts representative of the provided signal from each of the two or more separate ultrasound transmitters after interaction of the provided signal with a medium located within the coincident region;
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 the received wavefronts to make an initial guess at the selected one or more parameters; and
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;
using the refined parameters to determine a relative spatial position of the two or more separate ultrasound transmitters, and
performing a coherent signal combination of the received wavefronts received at the receiving array based on the provided signal from each of the two or more separate ultrasound transmitters after interaction of the provided signal with the medium located within the coincident region based upon the determined relative spatial position of each of the two or more separate ultrasound transmitters.
