    Abstract: Extracorporeal motion (130) 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 (164, 168) 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 (170) 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.

    Abstract: Existing gas pocket detection approaches are based on visual observations of B-mode ultrasound images showing comparisons between normal soft tissue and gas pockets, which are time-consuming and dependent on operator experience. The present invention proposes an ultrasound system and a method of detecting a gas pocket. The ultrasound system comprises: an ultrasound probe (110) for transmitting an ultrasound signal toward the ROI and acquiring an ultrasound echo signal reflected from the ROI along a plurality of scanning lines; an obtaining unit (130) for obtaining a second harmonic component of the ultrasound echo signal for each depth of a plurality of depths along each scanning line of the plurality of scanning lines; and a deriving unit (140) for deriving a change in a center frequency of the second harmonic component along with the depth.

    Abstract: Dynamically identifying a stationary body of fluid (102) within a test volume by scanning within the volume can entail using a first part of a pulse sequence to acoustically interrogate a region within the volume to detect pre-existing movement (124) and, via a separate acoustic interrogation constituting the second part of the pulse sequence, acoustically interrogating the region to distinguish solid from fluid. The scanning is with both interrogations as a unit, so as to span the volume with the interrogations. The body is identified, dynamically based on an outcome of the interrogations. The scanning may span, for the identifying, a current field of view (116), including normal tissue, within an imaging subject. The procedure, from scanning to identifying, may be performed automatically and without need for user intervention, although the user can optionally change the field of view to further search for stationary fluid.

    Abstract: A method and system is for assisting a user in positioning an ultrasound probe relative to a subject's body. In use, the user moves the probe through a series of positions, and ultrasound image data is captured for each position, the data at each position corresponding to a particular imaging view of the anatomical region being imaged. An assessment procedure (16) is operable to process ultrasound data for different imaging views, and to determine for the data for each view a rating, representative of the suitability of the data for that view for observing one or more anatomical features or deriving one or more clinical parameters from the data. Guidance feedback is generated (18) for the user for assisting the user in positioning the probe, wherein the guidance feedback is based on a history (26) of image view quality over time over the course of the imaging procedure. For example, a trend in image view quality over time may be determined and output to a user, from which the user can quickly tell whether they are moving toward (in the case of increasing quality) or away from (decreasing quality) an optimum imaging position.

    Abstract: An ultrasound system and method enable ultrasonic imaging by inexperienced personnel under the guidance of a remotely located diagnostic imaging expert. Improper use of the scanning device is prevented by controlling the device to present only low quality images to the person conducting the scan, while images of high quality are sent to the remote expert for diagnosis. Thus, an effective diagnosis by the expert is facilitated while providing at the scanning site only images which, while sufficient to provide visual guidance of the scanning procedure, cannot be used improperly by persons at the site of the patient being scanned.
