![]() ![]() The second line of transducers can be orthogonal to respective first lines in the transducer plane.Ībstract: An apparatus for ultrasound imaging of a body, particularly a breast of a patient, includes ultrasonic pulse-emitting and pulse-receiving units, disposed in facing relationship at a predetermined distance from each other on opposite sides of a compartment for receiving the body, ultrasonic pulses emitted by the emitting unit and received by the receiving unit after passing through the body being converted into transmit signals and an ultrasonic pulse emitting and receiving unit disposed to define a scan plane substantially perpendicular to the coronal plane of the patient and having one or more electro-acoustic transducers, which emit ultrasonic pulses into the body and receive echoes generated by the anatomic structures of the body, the echoes being converted into reflection signals. The separately determining the first or second sums of at least approximated complex samples can include phase-rotating at least some of the complex samples. ![]() Such apparatus or techniques can include separately determining, for respective focusing locations respective first sums of at least approximated complex samples of reflected ultrasonic energy obtained via respective first lines of transducers, and separately determining, for the specified focusing location, a second sum of at least some the respective first sums of at least approximated complex samples of reflected ultrasonic energy, the second sum corresponding to a second line of transducers in the ultrasonic transducer array. Abstract: Ultrasonic imaging apparatus or techniques can include obtaining at least an approximation of samples of reflected ultrasonic energy and constructing a representation of an imaging plane within the tissue region. ![]()
