Abstract: The present invention proposes an apparatus (120) and method for detecting bone fracture of a subject on basis of ultrasound images. The apparatus (120) comprises a first fracture detector (122) and a second fracture detector (124). The first fracture detector (122) is configured to receive a first ultrasound image of a region of the subject, to identify a bone in the first ultrasound image, to identify at least one focus area within the region on basis of the identified bone, to generate focus area information indicating position of the at least one focus area, and to instruct an acquisition of a second ultrasound image of the region acquired based on the generated focus area information. The second fracture detector (124) is configured to receive the second ultrasound image, and to detect bone fracture on the basis of the second ultrasound image. The second ultrasound image has a higher resolution in the at least one focus area than in the rest of the region, and the resolution of the at least one focus area in the second ultrasound image is higher than the resolution of the at least one focus area in the first ultrasound image.

Abstract: The present disclosure describes an ultrasound imaging system configured to identify a target placement of an ultrasound probe for viewing a lung pleural line. In some examples, the system may include an ultrasound probe configured to receive ultrasound echoes from a subject to image a region of the subject and a data processor in communication with the ultrasound probe. The data processor may be configured to identify one or more candidate pleural lines and one or more A-lines corresponding to the candidate pleural lines, compute an A-line intensity of at least one of the A-lines, and apply the computed A-line intensity to indicate a target placement of the ultrasound probe for imaging the region for pleural line identification. The system may also include a user interface in communication with the data processor. The user interface may be configured to alert the user of the target placement of the ultrasound probe.

Abstract: A system includes a transducer array configured to obtain ultrasound data of a subject; a processor in communication with the transducer array and a therapeutic device configured to deliver a therapy to the subject, wherein the processor is configured to: receive the ultrasound data; identify an anatomical feature of the subject using the ultrasound data; compute a measure associated with the anatomical feature; determine if the measure satisfies a threshold; determine a change in an operating status of the therapeutic device based on if the measure satisfies the threshold; and output, to the therapeutic device, a control signal representative of the change in the operating status. Associated methods, devices, and systems are also provided.

Abstract: An ultrasound control unit (12) is for configuring visualization of ultrasound data using in use a display unit. The control unit is adapted to acquire ultrasound image data and to automatically control visualization of the most relevant parts and views the data, based on current levels of a number of different monitored physiological parameters. In particular, responsively to one of the physiological parameters entering or leaving a pre-defined range of values (e.g. representative of an alert or normal condition respective for the patient), the control unit determines a most appropriate anatomical region within the image data for representing the changed physiological parameter, and a most useful visualization mode (e.g. view) for presenting or showing that anatomical region within the image data. One or more display frames are generated which show the anatomical region visualized in accordance with the selected visualization mode. A control output is generated for controlling a display panel to display the one or more display frames.

Abstract: A method (20) and device for deriving an estimate of intracranial blood pressure based on motion data for a wall of an intracranial blood vessel, intracranial blood flow velocity, and a blood pressure signal measured at a location outside the brain. The method is based on identifying (28) a time offset between the two intracranial signals (vessel wall movement and vessel blood flow), and then applying (30) this offset to the blood pressure signal acquired from outside the brain to obtain a fourth signal, indicative of estimated intracranial blood pressure.

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: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel at the home of a patient under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by allowing the remotely located imaging expert to enable or disable the transmission of ultrasound energy by the ultrasound system. Other functions of the ultrasound system may also be controlled by the remotely located expert, such as determining whether acquired ultrasound images can be viewed locally on the ultrasound system.

Abstract: An ultrasound imaging system is for determining stroke volume and/or cardiac output. The imaging system may include a transducer unit for acquiring ultrasound data of a heart of a subject (or an input for receiving the acquired ultrasound data), and a controller. The controller is adapted to implement a two-step procedure, the first step being an initial assessment step, and the second being an imaging step having two possible modes depending upon the outcome of the assessment. In the initial assessment procedure, it is determined whether regurgitant ventricular flow is present. This is performed using Doppler processing techniques applied to an initial ultrasound data set. If regurgitant flow does not exist, stroke volume is determined using segmentation of 3D ultrasound image data to identify and measure the volume of the left or right ventricle at each of end systole and end-diastole, the difference between them giving a measure of stroke volume. If regurgitant flow does exist, stroke volume is determined using Doppler techniques applied to ultrasound data continuously collected throughout a cardiac cycle.

Abstract: A Doppler ultrasound instrument (10) includes ultrasound pulse control and data acquisition electronics (12, 24, 26) for acquiring Doppler ultrasound data, an N-channel connector port (14) for simultaneously operatively connecting up to N ultrasound transducer patches (16) where N is an integer equal to or greater than two, and an electronic processor (30) programmed to concurrently determine up to N blood flow velocities corresponding to up to N patches operatively connected to the N channel connector port. The blood flow velocity for each patch may be determined by: determining transducer blood flow velocities for ultrasound transducers (60) of a transducer array of the patch; and determining the blood flow velocity for the patch as a highest determined transducer blood flow velocity or as an aggregation of highest determined transducer blood flow velocities.

Abstract: An imaging device positioning system for monitoring an anatomical region (10). The imaging device positioning system employs an imaging device (20) for generating an image (21) of an anatomical region (10). The imaging device positioning system further employs a imaging device controller (30) for controlling a positioning of the imaging device (20) relative to the anatomical region (10). During a generation by the imaging device (20) of the image (21) of the anatomical region (10), the imaging device controller (30) adapts the control of the positioning of the imaging device (20) relative to the anatomical region (10) to a physiological condition of the anatomical region (10) extracted from the image (21) of the anatomical region (10).
