Abstract
This disclosure describes systems and methods for crosstalk-free source encoding for ultrasound tomography. This disclosed systems and methods feature real data acquisition acceleration and/or numerical simulation acceleration (or image processing acceleration).
Claims31
A system for ultrasound tomography, comprising:
- a plurality of sources configured to transmit waves at one or more frequencies within a frequency bandwidth;
- one or more receivers configured to receive the waves transmitted by the plurality of sources;
- and
- a processor configured to:
- (a) use a computerized representation of physical property maps of a medium that influence wave propagation;
- (b) model all the sources and the receivers involved in a dataset;
- (c) associate to each of the sources a sinusoidal source time function with a defined frequency of a set of frequencies regularly spaced within a bandwidth of interest;
- and
- (d) perform a wave propagation simulation where sources are transmitting simultaneously for a time Tss+kΔτ, where k is an integer >=1.
