摘要： A method for anatomical imaging includes acquiring image data representative of three-dimensional volume segments of an image volume of interest in a subject. The image data are acquired in synchronism with corresponding physiological cycles of the subject. Each volume segment contains image data distributed in three dimensions. Acquiring image data includes selecting a sequence of scan lines for each respective volume segment configured to minimize an occurrence of motion artifacts throughout the image volume. The image data representative of the volume segments is combined to produce a representation of a three-dimensional anatomical image of the image volume.

摘要： A multiple aperture ultrasonic transducer having a linear array of elements, each element having a plurality of segments forming apertures of the array, and a connection assembly for interconnecting the segments and connecting the segments to circuits. The connection assembly includes an electrode layer directly adjacent to the segments, at least one insulating layer, and at least one connector layer. The electrode layer has an electrode area for each segment and one of the insulating layers has a connection opening for each segment and connection areas for pairs of segments while the connection layer has segment to segment connectors and segment pad connectors. Each element may be divided into sub-elements with connection cross-overs offset by one sub-element along the array and alternately reversed while alternate middle segments connect to alternate sides. The connection assembly may include interlayer connector layer and may be constructed onto a carrier which may be removed before attachment to a backing body, or the connection assembly may be deposited onto the array before attachment to a backing body. The connection assembly may be fabricated as a single assembly with a monolithic block of piezoelectric material and the assembly diced to a predetermined depth and across a predetermined width so that selected connections between electrode areas and to the pads remain intact. Interlayer vias are staggered and have clearance openings extending into the dicing kerf to reduce space and to insure connection after dicing.

摘要： A harmonic imaging transducer is a structure of two mechanically coupled piezoelectric layers. This two-layer piezoelectric structure may vibrate either in a symmetric mode, wherein the two layers are expanding and contracting in unison, or in an anti-symmetric mode, wherein one layer is contracting while the other is expanding. Symmetric mode vibrations result in first harmonic operation, while anti-symmetric mode vibrations result in second harmonic operation.

摘要： A micro-machined ultrasonic transducer (MUT) having aperture, elevation and apodization controlled by apparatus located on the same substrate as the transducer, or by bias voltage control applied to MUT elements, allows for an efficient and compact ultrasonic probe. The control apparatus may take the form of field effect transistors (FET's), micro-machined relays, or doped regions on the substrate, or any other apparatus that may be located on the same substrate as that of the transducer, or by bias voltage sources connected to the MUT elements.
