ABSTRACT:
An ultrasonic imaging system may include a transducer array having a novel distribution of transducer elements. Preferred embodiments of the system include a transducer having a linear, curved linear, or matrixed array of piezoelectric transducer elements. The transducer may include a novel distribution of transducer elements applied to the elevation elements, wherein the elevation aperture is divided into three sections, that is, a central section having an array of fine-pitched elements, and upper and lower sections. The novel distribution of transducer elements may be applied to the elevation elements wherein the system is adapted for a first mode of operation characterized as a near-field mode (e.g., at shallow depths), such that the transducer elements in the central section are activated to effect various purposes, e.g., beam steering and electronic focusing, and the transducer elements in the outer sections are generally not activated. The system is also adapted for a second mode of operation characterized as a far-field mode, wherein the transducer elements in both the central and outer sections are activated.
