    摘要： Beamforming to image an object (310), such as an interventional tool, is enhanced by initializing the beamformer (308) with the object's location, and optionally its orientation. The initializing uses an estimate of the location/orientation. The estimate is derived from the output of one or more sensors (304, 306). These are disposed external to the imaging array (316) that operates with the beamformer. The estimate is made without the need for a result of any imaging based on data arriving by reflected ultrasound. One or more of the sensors may be attached to the object, which may be elongated, as in the case of a needle or catheter used in medical diagnosis and treatment. In some implementations, one or more of the sensors are attached to the imaging probe (302). The sensors may be, for example, ultrasound, electromagnetic, optical, or shape sensors. Alternatively, ultrasound transmitting transducers may be substituted for the ultrasound sensors.

    摘要： An imaging system and method include a medical device (102) having a tracking element (106) mounted thereon. An array (109) of transducers is spaced apart from one another for exchanging energy in a subject between tracking element and the array of transducers. A trilateration module (104) is configured to interpret signals sensed between tracking element and the array of transducers to compute times of flight of signals associated with the transducers in the array such that a position of tracking element is determined in at least two dimensions to locate a position of the medical device in a visual image.

    摘要： Ultrasound aberration, especially in transcranial imaging or therapy, is corrected by capturing the laterally two-dimensional nature of the aberration in the ultrasound being received, as by means of a two-dimensional receiving transducer array (104, 108). In some embodiments, transmissive ultrasound (164) is applied through the temporal window and is, for example, emitted from one or more real or virtual point sources (160) at a time, each point source being a single transducer element or patch or the geometrical focus of a collection of elements or patches. A patch may serve, in one aspect as a small focused transducer in the near field. A contralateral array (104, 108) is, in one version, comprised of the point sources. In some aspects, aberration maps structured, independent-variable-wise, to correspond to the array structure of the receiving transducer embody aberration estimates, the ultrasound device being configured for improving ultrasound operation by modifying device settings to improve the location of ultrasound reception/transmission or correct beamforming. Enhancements include beam placement visualization, and intensity and beam shape prediction.
