An ultrasound diaphragmography device includes a plurality of piezoelectric ultrasound transducers arranged in at least two linear arrays for placement on a patient's chest along a cranio-caudal axis of the patient. The ultrasound transducers generate and transmit ultrasound waves that penetrate the patient's anatomy and receive returned ultrasound waves. Circuitry in communication with the ultrasound transducers receive the returned ultrasound waves and analyzes the returned ultrasound waves to determine the quality of the patient's lung function in real-time and compare the movement of the left and right hemidiaphragms.

Disclosed are a method for playing a CEUS movie file, an ultrasound movie file, and ultrasound apparatus. The method comprises: receiving a playing instruction for the movie file which is a dynamic data of generated by ultrasound echoes returned from a target tissue to which ultrasound waves are transmitted by a probe of an ultrasound apparatus; determining an imaging frame rate of the ultrasound images; determining a playback frame rate of the movie file according to the imaging frame rate negatively correlated with the playback frame rate; and playing the movie file with the playback frame rate. By using the playback frame rate which is negatively correlated with the imaging frame rate to play movie files, the movie files with low frame rate can be played more smoothly and the movie files with high frame rate can be played in line with the look and feel of the human eye.

A system and method is provided for providing an indication of viewable and non-viewable parts of an interventional device in an ultrasound image. The system includes a processing unit including a detection and recognition system configured to detect a pattern of echogenic features within ultrasound images, and a memory unit operably connected to the processing unit storing information regarding echogenic patterns on individual interventional devices. The detection and recognition system determines viewable and non-viewable parts of detected echogenic patterns in the ultrasound image by comparing the dimensions of the stored echogenic patterns with the representation of the detected echogenic patterns in the ultrasound images and positions an indicator within the ultrasound image on the display in alignment with the locations of the viewable and non-viewable parts of the detected echogenic patterns on the interventional device.

Arrangements described herein relate to a headset. The headset includes a device. The device includes a transducer configured to interact with a head of a subject. The headset further includes a manually-operated registration system configured to delineate a workspace of the transducer at the head of the subject.

Disclosed are methods and apparatus for viewing a contrast-enhanced ultrasound image and a dynamic data. The method comprises: receiving a first operation, for setting a first viewing range by a first browsing step length that is multiple frames; in response to the first operation, positioning the image data to a viewing neighborhood containing the first viewing range; receiving a second operation, on the view neighborhood by a second browsing step length that is a single frame; in response to the second operation, determining a current image frame corresponding to when the second operation is performed in the viewing neighborhood, and further positioning the image data to an adjacent frame of the current image frame to the user to view frame by frame. As such, doctors are helped to accurately locate desired image frames to significantly improve browsing efficiency with convenient operation and high user-friendliness to save time and reduce workload.

A method for two-dimensional sheare wave elastography imaging comprises: a) acquiring B-mode ultrasound images of a target region in a body; b) selecting a region of interest inside the B-mode image; c) transmitting a shear wave excitation pulse focalized on an excitation region; d) measuring displacements of tracking focal points at different depths positions along laterally staggered tracking lines within the region of interest; e) determining elasticity parameters of the regions between two of the tracking focal points at the same depth and on at least two adjacent tracking lines as a function of the displacements caused by the shear wave at the tracking focal points; f) modifying the appearance of pixel(s) of the B-mode image inside the regions relatively to the grey-scale B-mode image as a function of elasticity parameters determined for the regions; and g) displaying the pixel(s) having a modified appearance at the corresponding pixel of the B-mode image.

A temporal change at each coordinate of interest which is spatially fixed in frame data of a plurality of time phases obtained by transmitting and receiving ultrasound is made understandable. A trace processor derives an amount of temporal change at each coordinate of interest of a plurality of coordinates of interest which are spatially fixed in the frame data over a plurality of time phases. The trace processor also derives an amount of spatial movement of each site of interest based on the amount of temporal change of each coordinate of interest near each site of interest. Further, the trace processor derives an amount of spatial movement of each site of interest for each time phase over a plurality of time phases in a trace period, and traces a motion of each site of interest in the trace period based on the amount of movement derived for each time phase.
