CURVED 2-D ARRAY ULTRASOUND TRANSDUCER AND METHOD FOR VOLUMETRIC IMAGING |
摘要 |
An ultrasound imaging system includes an imaging probe having an array of transducer elements that is flat and relatively elongated in the azimuth direction and is curved outwardly in the elevation direction. As a result, when the transducer elements are scanned in a step-wise manner, the acoustic pattern of the probe diverges in the elevation direction. The probe therefore provides a large field of view in the near field despite using relatively few transducer elements. The probe also includes sub-array beamformers to delay signals transmitted and received from the transducer elements in respective sub-arrays. The received signals are coupled to an imaging system which includes a signal path that processes the received signals into signals corresponding to a volumetric image. A display coupled to the signal path can then show a volumetric image of anatomical features in a volumetric region adjacent the array of transducer elements. |
