    Abstract: A system for determining a position of an interventional device (11) respective an imaging field (B1 . . . k) corresponding to a type (T1 . . . n) of a beamforming ultrasound imaging probe (13) currently connected to an ultrasound imaging system (14). The position is determined based on ultrasound signals transmitted between the beamforming ultrasound imaging probe (13) and an ultrasound transducer (15) attached to the interventional device (11). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI) corresponding to the imaging field (B1 . . . k). A position determination unit (PDU) receives input indicative of the type (T1 . . . k) of the beamforming ultrasound imaging probe (13) currently connected to the ultrasound imaging system (14). The position determination unit (PDU) also computes a position (LAPTOFFSmax, θIPA) of the ultrasound transducer (15) respective the imaging field (B1 . . . k). Computing the position (LAPTOFSmax, θIPA) comprises selecting from a group of beam sequences corresponding to a plurality of imaging probe types (T1 . . . n) a beam sequence corresponding to the type (T1 . . . n) of the beamforming ultrasound imaging probe (13) currently connected to the ultrasound imaging system (14) and assigning detected ultrasound signals to the selected beam sequence.

    Abstract: An ultrasound imaging system according to the present disclosure may include an ultrasound transducer assembly comprising a plurality of apertures that are configured to transmit signals toward and receive signals from a region of interest (ROI) of a subject, a tracking sensor disposed within the subject and configured to move within the ROI, the sensor being responsive to signals transmitted by the apertures, and at least one processor in communication with the ultrasound transducer assembly and the tracking sensor. The at least one processor may be configured to generate a first image of a first portion of the ROI from signals received from at least one activated aperture, identify a position of the tracking sensor using signal data from the tracking sensor that corresponds to at least one signal transmitted by the apertures, and generate a second image of a second portion of the ROI from signals received from at least one other aperture activated based on the identified position, wherein the second portion of the ROI is different from the first portion of the ROI.

    Abstract: A system for localizing a three-dimensional field of view of a beamforming ultrasound imaging probe based on a position indicator disposed within said field of view. The beamforming ultrasound imaging probe transmits and receives ultrasound signals within a three-dimensional field of view comprising a plurality of predetermined sub-volumes, each sub-volume being defined by a two dimensional array of beams. A controller causes the beamforming ultrasound imaging probe to scan the sub-volumes sequentially by transmitting and receiving ultrasound signals corresponding to each beam. A tracking system determines a position of the position indicator within the three-dimensional field of view; and determines a sub-volume in which the position indicator is located. The controller causes the beamforming ultrasound imaging probe to provide a localized field of view including the position of the position indicator by constraining the transmitting and receiving of ultrasound signals to a portion of the sub-volume in which the position indicator is located.

    Abstract: A controller (250) for identifying out-of-plane motion of a passive ultrasound sensor (S1) relative to an imaging plane front an ultrasound imaging probe includes a memory (391) licit stores instructions and a processor (392) that executes the instructions. When executed by the processor, the instructions cause a system that includes the controller (250) to implement a process that includes obtaining (S710). from a position and orientation sensor (212) fixed to the ultrasound imaging probe (210), measurements of motion of the ultrasound imaging probe (210) between a first point in time and a second point in time. The process implemented by the controller (250) also includes obtaining (S720) intensity of signals received by the passive ultrasound sensor (S1) at the first point in time and at the second point in time based on emissions of beams from the ultrasound imaging probe (210), and determining (S730), based on the measurements of motion and the intensity of signals, directionality of and distance from the passive ultrasound sensor (S1) to the imaging plane.

    Abstract: A controller (210) for tracking an interventional medical device (252) in three dimensions includes a memory (212) that stores instructions, and a processor (211) that executes the instructions. When executed by the processor (211), the instructions cause the controller (210) to execute a process. The process includes determining (S320/S420), based on an elevation plane in an ultrasound X-plane mode, a first two-dimensional location of the interventional medical device (252) in the elevation plane. The process also includes determining (S320/S422), based on an azimuthal plane in the ultrasound X-plane mode, a second two-dimensional location of the interventional medical device (252) in the azimuthal plane. The process moreover includes determining (S330/S430), based on the first two-dimensional location and the second two-dimensional location, a three-dimensional location of the interventional medical device (252). Finally, the process includes modifying (S340/S440) ultrasound beam patterns fired in the ultrasound X-plane mode based on the three-dimensional location of the interventional medical device (252).

    Abstract: A radiation therapy system (1) includes an ultrasound (US) imaging unit (2), a registration unit (30), an US motion unit (44), and a real-time dose computation engine (46). The ultrasound (US) imaging unit (2) generates a baseline and real-time US images (3) of a subject body (4) region including a target and one or more Organs At Risk (OARs). The registration unit (30) deformably registers a planning image (32) and the baseline US image (36), and maps (66) radiation absorptive properties of tissue in the planning image (32) to the baseline US image (36). The US motion unit (44) measures motion of the target volume and OARs during radiation therapy treatment based on the real-time US images. The real-time dose computation engine (46) computes a real-time time radiation dose delivered to the tissues based on the tissue radiation absorptive properties mapped from the baseline or planning images to the real-time 3D US images (3).
