Method for ultrasonic imaging, particularly of moving bodies, such as surgical utensils, tissues, flows, or the like
First Claim
1. A method for ultrasonic imaging, particularly of moving bodies, such as surgical utensils, tissues, flows, or the like, which includes the following steps:
- Periodically emitting ultrasonic pulses along a predetermined view line and with a predetermined repetition rate through one or more transducers;
Receiving the echoes produced by the body and/or the tissues or flows and transforming them into echo signals;
Processing the echo signals for extracting information therefrom and for generating an image based on such information, characterized by the following additional steps;
determining a real time vector difference between the echo signals of two pulses successively emitted at predetermined time intervals;
using said difference signal as an information signal for ultrasonic imaging.
