In a method for making a measurement of the hip in an ultrasound image, an ultrasound image of the hip is obtained. A spatial coherence map associated with one or more lags of the ultrasound waves associated with the ultrasound image is also obtained. Then a quality metric is determined based on the ultrasound image of the hip and the spatial coherence map. The quality metric indicates the suitability of the ultrasound image for making the measurement of the hip. If the quality metric indicates that the ultrasound image is above a threshold quality, then the method then comprises indicating that the ultrasound image is suitable for making the measurement of the hip.

Making measurements of the hip

The present disclosure describes ultrasound imaging systems and methods configured to identify lung abnormalities by determining a uniformity characteristic of a region of interest within ultrasound image frames. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward a pulmonary target region. A processor coupled with the transducer may be configured to generate an image frame from the acquired echoes and determine a uniformity characteristic of the region of interest below a pleural line in the image frame. The processor may also be configured to determine a presence or absence of a lung abnormality, e.g., lung consolidation, within the region of interest based on a value of the uniformity characteristic. If a lung abnormality has been determined to be present, the processor can generate an indicator of the same, which may be displayed on a user interface in communication with the processor.

Ultrasound system for detecting lung consolidation

The present invention proposes an apparatus () and method for detecting bone fracture of a subject on basis of ultrasound images. The apparatus () comprises a first fracture detector () and a second fracture detector (). The first fracture detector () 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 () 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.

Systems, devices, and methods are provided to provide serial monitoring for a patient. An ultrasound system is provided which may include subdividing a portion of the anatomy of a patient into a number of zones. Imaging data may be received by an imaging device. This imaging data may be used to generate a severity score for each zone based on imaging parameters within the imaging data. Changes in the severity score for each zone may be displayed over time, such that a medical professional may monitor each zone in a serial manner.

Devices, systems, and methods for guiding repeated ultrasound exams for serial monitoring

Ultrasound image devices, systems, and methods are provided. In one embodiment, an ultrasound imaging system includes an interface coupled to an ultrasound imaging component and configured to receive a plurality of image data frames representative of a subject's body including at least a portion of a lung; a processing component in communication with the interface and configured to determine a metric for each image data frame of the plurality of image data frames based on a threshold comparison; and determine a dynamic air bronchogram (AB) condition of the subject's body based on a variation across the metrics of the plurality of image data frames. In one embodiment, the processing component is configured to determine differential data frames based on differences across consecutive image data frames of the plurality of image data frames; and determine a dynamic AB condition of the subject's body based on the differential data frames.

The present invention proposes an ultrasound system and a method of detecting lung sliding on the basis of a temporal sequence of ultrasound data frames of a first region of interest. The first region of interest includes a pleural interface of a lung. A sub-region identifier () is configured to identify, for each of the ultrasound data frames, a sub-region of a scanned region of the ultrasound data frame, the sub-region comprising at least part of the pleural interface; a lung sliding detector () is configured to derive a parametric map for the sub-region on the basis of at least two ultrasound data frames of the temporal sequence, parametric values of the parametric map indicating a degree of tissue motion over the at least two ultrasound frames; wherein the lung sliding detector is further configured to extract data of the sub-regions from the at least two ultrasound data frames, and to derive the parametric map on the basis of the extracted data.

Extracorporeal motion () relative to a medical subject being imaged is detected, through the imaging or from motion detectors on the imaging probe, and either backed out of the medical images so that it can be determined whether lung sliding exists or measured to determine whether lung sliding detection is to be suspended due to excessive extracorporeal motion. Image sub-regions () corresponding to respective ones of the images are selected for image-to-image comparison such that the selected sub-regions contain only body tissue that is, with respect to imaging depth in the acquiring of the images, shallower than an anatomical landmark within the images. Based on a result of the comparing, lung sliding detection that entails examining image data deeper than the landmark may be initialized. A motion sensor may detect the extracorporeal motion and, based on its output: pair-wise co-register () images to an extent of backing out the effect of the extracorporeal motion and/or determine whether to suspend deciding as to whether lung sliding is, during the respiration, occurring in the subject.

Distinguishing lung sliding from external motion

The invention relates to an ultrasound system () for sequentially performing a predetermined procedure for each of at least one region of interest. The ultrasound system () comprises an ultrasound probe () configured to transmit a first ultrasound signal (SG) towards a region of interest and receive echo signals from the region of interest. The ultrasound system () also comprises a motion sensor () configured to detect a motion of the ultrasound probe () and generate a motion signal (MS) for indicating the motion of the ultrasound probe (). The ultrasound system () also comprises a processor () configured to perform a predetermined procedure for a region of interest on the basis of the echo signals received from the region of interest if the motion signal (MS) indicates that the ultrasound probe () is stationary. The invention also relates to a corresponding ultrasound method.

Ultrasound system and method for detecting pneumothorax

A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds as a function of the range between the wireless probe and a host system. When the probe is within a near field range of the host system, the loudspeaker is silent. But if the probe is moved to an intermediate or a far field range from the host system, the loudspeaker sounds an alert. This audible alert can be used to locate the probe by transmitting a paging signal which, upon reception by the probe, causes the probe to sound its alert. If the probe is moved to an unauthorized location where it is within range of a transmitter or receiver, the reception of a signal by the probe, the transmitter, or receiver will sound an alert signaling the unauthorized presence of the wireless probe.
