    Abstract: A controller (310) for identifying positioning of an intravascular ultrasound probe (952) includes a memory (362) that stores instructions (884) and a processor (361) that executes the instructions (884). When executed by the processor (361), the instructions (884) cause the controller (310) to execute a process that includes receiving first signals from at least one element of the intravascular ultrasound probe (952). The process also includes receiving second signals from an external ultrasound probe. Based on the first signals and the second signals, the controller (310) determines a position of the intravascular ultrasound probe (952) in a tracking space that includes the intravascular ultrasound probe (952) and the external ultrasound probe.

    Abstract: The invention relates to a temperature distribution determination apparatus for determining a temperature distribution within an object (20), while an energy application element (2) applies energy to the object, especially while an ablation procedure for ablating a tumor within an organ is performed. A time-dependent first ultrasound signal is generated for an ultrasound measurement region within the object and a temperature distribution within the object is determined based on the generated time-dependent first ultrasound signal and based on a position of the energy application element (2) relative to the ultrasound measurement region tracked over time. This can ensure that always the correct position of the energy application element, which may be regarded as being a heat source, is considered, even if the energy application element moves, for instance, due to a movement of the object. This can lead to a more accurate determination of the temperature distribution.

    Abstract: Ultrasound imaging devices, systems, and methods are provided. In one embodiment, an ultrasound imaging system comprising a processor configured to receive ultrasound channel data representative of a subject's anatomy generated from an ultrasound transducer; apply a predictive network to the ultrasound channel data to generate an image of the subjects anatomy; and output, to a display in communication with the processor, the image of the subjects anatomy. In one embodiment, a system for generating an image, the system comprising a memory storing at least one machine learning network; and a processor in communication with the memory, the processor configured to receive raw channel data generated from an ultrasound transducer; apply the machine learning network to the raw channel data to replace one or more image processing steps, thereby generating modified data; and generate an image using the modified data.

    Abstract: A system and method for tracking an interventional tool based on a spatial alignment of two or more acoustic sensors relative to the interventional tool include operating an acoustic imaging device to generate an acoustic image plane, and operating each acoustic sensor to output a composite acoustic sensing waveform derived from an acoustic sensing of the acoustic beam array. Each composite acoustic sensing waveform can include a plurality of acoustic beam sensing waveforms. The system and method can further include operating a tracking workstation to track a position of the interventional tool relative to the acoustic image plane derived from a waveform profile analysis of the composite acoustic sensing waveforms.

    Abstract: A radiation therapy delivery system (10) includes an ultrasound imaging unit (26), a radiation therapy delivery mechanism (12, 56, 70, 88), a plurality of fiducials (22, 90) located internal to the subject, an image fusion unit (40), and a delivery evaluation unit (38). The ultrasound imaging unit (26) includes a transducer (30) that emits ultrasonic sound waves to image in real-time an anatomic portion of a subject (16) in a first coordinate system. The radiation therapy delivery mechanism (12, 56, 70, 88) delivers amounts of therapeutic radiation in the anatomic portion of the subject in a second coordinate system. The fiducials (22, 90) include implants or a trans-rectal ultrasound probe (80). The image fusion unit (40) registers locations of the plurality of fiducials to at least one of the first and the second coordinate system and tracks the locations of the fiducials in real-time. The delivery evaluation unit (38) identifies locations and the amounts of delivered therapeutic radiation relative to the imaged real-time anatomic portion of the subject.
