Classification: CPC A | IPC A

Claim 10:
11. A method of tissue characterization using an acousto-electric effect comprising:
a. providing at least one waveform generation controller for generating a plurality of acoustic waveforms;
b. irradiating said tissue with said plurality of acoustic waveforms;
c. detecting an acoustoelectric voltage signal by means of at least one set of electrodes;
d. processing and analyzing said acoustoelectric voltage signal by at least one signal processing unit;
e. generating information indicative to at least one property of multiple locations within said tissue taking into account said acousto-electric effect;
wherein said at least one waveform generation controller comprises instructions for:

i. generating said plurality of waveforms according to at least one parameter, each of said plurality of waveforms comprising a coded sequence which is different from other coded sequences comprised in other generated waveforms; said plurality of different sequences being used in said analyzing by said at least one signal processing unit; said at least one parameter being a low maximal absolute value of cross correlation between said sequences thereby providing a maximal signal to interference ratio between generated waveforms; and
ii. transmitting said generated plurality of waveforms;
wherein said analyzing comprises separating contributions from each of said received signals based on said difference in said coding sequence of each of said waveforms.
