    Abstract: A process implemented by a controller (120/220/320) with a circuit (121-126/221-226/321-351) includes receiving (S410) a signal stream between an ultrasound imaging probe (110/210/310) that emits multiple beams and a console (190/290/390) that receives image signals from the ultrasound imaging probe (110/210/310). The signal stream includes synchronization information indicating timing of emission of each beam, and the circuit (121-126/221-226/321-351) extracts the synchronization information. The circuit (121-126/221-226/321-351) receives (S430), from a passive ultrasound sensor (S1) that receives energy from each beam, a first signal that includes first sensor information indicative of a location of the passive ultrasound sensor (S1) and generated based on receipt by the passive ultrasound sensor (S1) of the energy received from each beam. A second signal with a predefined signature characteristic indicating the timing of emission of each beam is added (S450) to the first signal based on the synchronization information. The circuit the second signal.

    Abstract: An ultrasound control unit (10) is for coupling with an ultrasound transducer unit (12). The control unit is adapted to control a drive configuration or setting of the transducers of the transducer unit, each drive setting having a known power consumption level associated with it. The control unit includes a control module (20) adapted to adjust the drive setting from a first setting to a second setting, the second having a lower associated power consumption that the first. The second setting is tested by an analysis module (16), the analysis module adapted to determine a measure of reliability of ultrasound data acquired by the transducer unit, for the purpose of deriving at least one physiological parameter, when configured in the second setting. The second setting is only used if its determined reliability passes a pre-defined reliability condition.

    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: A controller (220) for determining a shape of an interventional medical device in an interventional medical procedure based on a location of the interventional medical device includes a memory (221) that stores instructions and a processor (222) that executes the instructions. The instructions cause a system (200) that includes the controller (220) to implement a process that includes obtaining (S320) the location of the interventional medical device (201) and obtaining (S330) imagery of a volume that includes the interventional medical device. The process also includes applying (S340), based on the location of the interventional medical device (201), image processing to the imagery to identify the interventional medical device (201) including the shape of the interventional medical device (201). The process further includes (S350) segmenting the interventional medical device (201) to obtain a segmented representation of the interventional medical device (201). The segmented representation of the interventional medical device (201) is overlaid (S360) on the imagery.

    Abstract: A controller (120) for simultaneously tracking multiple sensors in a medical intervention includes a circuit (121-181) that causes the controller (120) to execute a process. The process executed by the circuit (121-181) includes receiving first and second signals respectively from a first and a second passive ultrasound sensor (S2) used in the medical intervention. The first and second signals respectively include first and second sensor information indicative of respective locations of the first and the second passive ultrasound sensor (S2). The process executed by the circuit (121-181) also includes combining (120) the first signal and the second signal for transmission over only one channel, and providing the first signal and the second signal over the only one channel to a system (190) that determines the location of the first passive ultrasound sensor (51) and the location of the second passive ultrasound sensor (S2) and that has only the one channel to receive the first signal and the second signal.

    Abstract: A system (100) and method (190) for determining the reliability of an ultrasonic tracking device (102) includes a determination device (132) that is configured to receive signals from the ultrasonic tracking device and determine a quantity of sensors (105) of an interventional device (103) in a field of view of the ultrasonic imaging device. An evaluation device (136) correlates a quantity of the sensors in the field of view with a reliability level for the determined orientation of the interventional device and generates a control signal (142) to a feedback device. The feedback device provides feedback to the user concerning the reliability level for the orientation of the interventional device determined by the ultrasonic tracking device. The feedback may be visual and/or audible feedback.
