Abstract
A method for determining a physical characteristic on a punctual location inside a medium, comprising the steps of: sending an emitted sequence comprising emitted pulses having different amplitudes, receiving a received sequence comprising received pulses corresponding to echoes of said emitted pulses, calculating a phase difference between the received pulses relative to the emitted pulses, and determining the physical characteristic on the bases of said phase difference.
Claims25
A method for determining a physical characteristic on a punctual location inside a medium, comprising the following steps:
- a) sending an emitted sequence of ultrasound waves into the medium towards the location, the emitted sequence comprising at least two emitted pulses having different amplitudes,
- b) receiving a received sequence of ultrasound waves from the location, the received sequence comprising at least two received pulses corresponding to echoes of said emitted pulses,
- c) calculating a phase difference between the received pulses relative to the emitted pulses, and
- d) determining the physical characteristic on the bases of said phase difference.
A method for determining an image of a region inside a medium, the image being composed of a plurality of pixels, and wherein the method comprises for a plurality of locations inside the region, the following steps:
- a) sending an emitted sequence of ultrasound waves towards the location into the region, the emitted sequence comprising at least two emitted pulses of different amplitudes,
- b) receiving a received sequence of ultrasound waves from the location, the received sequence comprising at least two received pulses corresponding to said emitted pulses,
- c) calculating a phase difference between the received pulses relative to the emitted pulses, and
- d) determining the pixel of the image on the bases of said phase difference.
