Abstract
A method of generating an image of a scanned subject includes: emitting, by multiple ultrasonic elements of an array, multiple respective ultrasonic signals into a subject, the multiple respective ultrasonic signals defining at least two beam portions traveling in different directions; receiving, by the multiple ultrasonic elements, multiple respective ultrasonic echo signals; and generating at least one image of a portion of the subject from the received multiple ultrasonic echo signals. A negatively focused wavefront including the at least two beam portions traveling in the different directions may be emitted. Multiple negatively focused wavefronts may be generated and emitted.
Claims15
A method of generating an enhanced image, the method comprising:
- acquiring multiple sequential scans, in each of the scans:
- emitting, by multiple ultrasonic elements of an array, multiple respective ultrasonic signals into a subject, the multiple respective ultrasonic signals defining at least two beam portions traveling in different directions;
- receiving, by the multiple ultrasonic elements, multiple respective ultrasonic echo signals;
- generating, by the multiple ultrasonic elements, multiple respective receive signals caused by the ultrasonic echo signals;
- and
- storing scan data of the subject using the multiple receive signals;
- combining the scan data of two or more of the multiple sequential scans using weights to implement at least one of temporal and spatial processing;
- and
- generating at least one enhanced image of a portion or all of the subject using the combined scan data.
