摘要:
An ultrasonic apparatus and method are described in which a volumetric region of the body is imaged by biplane images. One biplane image has a fixed planar orientation to the transducer, and the plane of the other biplane image can be varied in relation to the fixed reference image. In a preferred embodiment one image can be rotated relative to the other, and can be tilted relative to the other. An image orientation icon is shown on the display screen together with the two biplane images depicting the relative orientation of the two planar images.

An ultrasound-imaging system and method is provided that permits an operator to acquire an image of a volume-of-interest in a time critical fashion, that is capable of referencing the volume rendering to a standard two-dimensional imaging mode, and permits the operator to selectively choose a number of display-mode parameters that result in an operator directed view of the volume-of-interest. The ultrasound-imaging system comprises an input device configured to receive a plurality of imaging parameters and a controller in communication with the input device. The ultrasound-imaging system generates an operator-directed transmit-beam scan sequence in response to the imaging parameters and transmits a spatially modified transmit-beam scan sequence over a portion of the volume-scan range of the ultrasound-imaging system. Moreover, the ultrasound-imaging system provides the flexibility for an operator to direct a plurality of operator-configurable multi-dimensional views.

A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. The invasive medical device (30) is shown in a detailed ultrasonic image and the balance of the volumetric region (120) in which the device is located is shown in a wide field of view. The detailed and wide fields of view may be displayed separately or overlapping in spatial alignment on an image display (18). The wide field of view may be shown in two or three dimensions. A quantified display may be shown together with the wide and detailed anatomical displays. The detailed view may also be shown in an enlarged or zoomed format.

A composite three dimensional ultrasound image containing position or image information of an invasive medical device (30) is provided. The three dimensional ultrasound image data can be combined with position or image information of the invasive medical device (30) either prior to or subsequent to volume rendering. the three dimensional ultrasound image data and the interventional system data are oriented and sealed to a common frame of reference and then combined. The volume rendering can be performed either on the ultrasound system (12), on the interventional system (20), or separately on both before combining.

摘要:
An ultrasonic diagnostic imaging system has a two dimensional array arranged in multiple patches of multiple transducer elements. Each patch of transducer elements is coupled to a group of microbeamformer delay lines having outputs coupled to a channel of a system beamformer, which beamforms the partially summed beams of each patch into a final beamformed signal. The outputs from multiple patches which are not simultaneously used in the active receive aperture are coupled to a common beamformer channel, enabling the number of patches of the array to exceed the number of channels of the system beamformer without the use of multiplexers.

Apodization control techniques for a microbeamformer including a plurality of microbeamformer channels each including a transducer, a microbeamformer transmitter for driving the transducer, a microbeamformer receiver for receiving signals from the transducer and usually a delay element for delaying the received transducer signals. To improve the generation of waveforms by the transducers, the voltage provided to the microbeamformer transmitters is adjusted and/or the current provided by the microbeamformer transmitters is adjusted. The microbeamformer channels can also be grouped together into patches and/or clusters with the patches and clusters being provided with a common voltage source or current.

A method and a system for using redundant wire bonds (24) for increasing the reliability of ultrasound transducers is disclosed. An ultrasound transducer assembly having an ultrasound transducer, an integrated circuit (20), a plurality of wires (24), and a plurality of bond pads is provided. The integrated circuit includes enlarged lead pads for receiving redundant wire bonds. The ultrasoundtransducer includes a plurality of bond pads configured to receive the redundant wire bonds. Connecting wires, forming signal paths, connect the enlarged lead pads with the bond pads.
摘要:
The present invention combines the benefits of aberration correction with the benefits of microbeamforming in an ultrasound diagnostic imaging system, such that both partial beamforming (in the microbeamformer) and at least some part of the phase aberration detection correction processes are accomplished in the transducer probe proximate the transducer array. Accordingly, aberration correction applied at or proximate the microbeamformer in the transducer probe results in a significant simplification of the overall aberration correction technique for the entire ultrasound diagnostic imaging system.
