First Claim
1. A method for imaging, comprising:
- directing a plurality of radio frequency (RF) beams toward a target organ from a respective plurality of angles, the plurality of the RF beams comprising one or more first pairs of the RF beams, each first pair comprising two of the RF beams that impinge on the target organ from opposite directions;
receiving RF signals reflected from the target organ responsively to the RF beams, the RF signals comprising one or more second pairs of the RF signals engendered respectively by the one or more first pairs of the RF beams using a processor to perform the following steps;
extracting local tissue parameters at multiple points in the target organ by jointly processing the RF signals in each of the second pairs; and
producing images of the target organ using the extracted local tissue parameters.

Abstract
A method for imaging includes directing a plurality of radio frequency (RF) beams (206, 207) toward a target organ from a plurality of angles. The RF beams include one or more first pairs of the RF beams, each first pair including two of the RF beams that impinge on the target organ from opposite directions. RF signals reflected from the target organ are received responsively to the RF beams, the RF signals including one or more second pairs of the RF signals engendered respectively by the one or more first pairs of the RF beams. Local tissue parameters at multiple points in the target organ are extracted by jointly processing the RF signals in each of the second pairs. Images of the target organ are produced using the extracted local tissue parameters. Other embodiments described herein include methods for passive imaging, motion vector analysis, ablation, local heating and application of electromagnetic pressure.
