ULTRASOUND APPARATUS AND METHOD OF DISPLAYING ULTRASOUND IMAGES
An ultrasound apparatus includes: a first display; a second display including a touch panel receiving a user input; a memory storing one or more instructions; and a processor. The processor is configured to execute the one or more instructions to: obtain a first raw data and a first TGC information corresponding to the first raw data from a storage medium; obtain a first ultrasound image by applying the first TGC information to the first raw data; control the first display to display the first ultrasound image; control the second display to display the first TGC information and receive a user input for modifying the first TGC information to a second TGC information; update the first ultrasound image by applying the second TGC information to the first raw data; and control the first display to display the updated first ultrasound image.
Systems and methods for improving ultrasound image quality by applying weighting factors
Systems and methods for improving the quality of ultrasound images made up of a combination of multiple sub-images include giving more weight to sub-image information that is more likely to improve a combined image quality. Weighting factor information may be determined from the geometry (e.g., angle or path length) of a location of one or more specific transducer elements relative to a specific point within a region of interest or a region of an image. In some embodiments, any given pixel (or other discrete region of an image) may be formed by combining received echo data in a manner that gives more weight to data that is likely to improve image quality, and/or discounting or ignoring data that is likely to detract from image quality (e.g., by introducing noise or by increasing point spread).
Ultrasound method and ultrasound system for real time automatic setting of parameters for doppler imaging modes
To lessen the examination time in an Ultrasound system in a vascular Exam routine, it is desirable to: automatically position in the best way Color Doppler ROI and/or Sample Gate; select the best Color Doppler/Beamline Steering angle; and set the Doppler Correction angle. An algorithm is provided that is able to process in real time the Doppler Signal to identify the Doppler Area where the most significant flow is present, and then it analyzes the ‘Shape’ of such Color Doppler Area identifying the Position and direction of the “main” Flow. The vascular Examination routine can therefore be made easier and faster.
ULTRASOUND IMAGING SYSTEM MEMORY ARCHITECTURE
A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.
Acoustic wave processing device, signal processing method for acoustic wave processing device, and program
The acoustic wave processing device includes a data processing unit which performs superimposition processing on first element data or first reception data generated by performing phasing addition on the first element data to generate processed data, an image generation unit which generates a B mode image based on the first element data and the processed data, a bloodstream image generation unit which generates a bloodstream image based on bloodstream information included in the first element data, a region setting unit which sets a bloodstream image region, a processing region setting unit which sets a region for processing in the data processing unit based on information relating to the bloodstream image region, and a display image generation unit which generates a synthesized image of the B mode image and the bloodstream image.
ULTRASONIC IMAGING OF ACOUSTIC ATTENUATION COEFFICIENTS WITH ELEVATION COMPOUNDING
An ultrasound system produces maps of acoustic attenuation coefficients from B mode image signals. A plurality of maps located in different parallel and elevationally separated planes (A, B, C, D, E) are produced, then compounded in the elevation direction. Confidence maps may also be produced for one or more attenuation coefficient maps, and the confidence map displayed or its measures used to determine weighting for the compounding process. The compounding of elevationally separate planes improves attenuation coefficient estimation in the presence of blood vessels affecting the estimates in one or more of the planes.
Providing user interface in ultrasound system
There are provided embodiments for providing a user interface for performing a filtering process upon a vector Doppler image. In one embodiment, by way of non-limiting example, an ultrasound system comprises: a processing unit configured to form vector information of a target object based on ultrasound data corresponding to the target object and form a user interface for performing the filtering process upon the vector Doppler image based on the vector information.
Ultrasonic diagnostic device, signal processing device, and program
A shear wave velocity is accurately measured. Time change data of a displacement of a tissue due to a shear wave generated in a test object is calculated from a reception signal obtained by transmitting an ultrasonic wave to the test object and receiving a reflected wave. The time change data of the displacement is converted into spectrum data indicating a displacement distribution in a frequency space having a spatial frequency and a time frequency as two axes. Spectrum data in a predetermined region is extracted by rotating the spectrum data by a predetermined angle in the frequency space, and filtering the rotated spectrum data. A velocity of the shear wave is calculated based on the extracted spectrum data in the predetermined region.
Ultrasonic diagnostic apparatus and method for controlling pulse repetition frequency
The ultrasonic diagnostic apparatus according to the present embodiment includes processing circuitry. The processing circuitry is configured to determine a scan region of an ultrasonic wave according to a scan target. The processing circuitry is configured to set a pulse repetition frequency for each raster of rasters so as to correspond to the scan region. The processing circuitry is configured to control a scan performance according to the pulse repetition frequency.

Systems and methods for improving the quality of ultrasound images made up of a combination of multiple sub-images include giving more weight to sub-image information that is more likely to improve a combined image quality. Weighting factor information may be determined from the geometry (e.g., angle or path length) of a location of one or more specific transducer elements relative to a specific point within a region of interest or a region of an image. In some embodiments, any given pixel (or other discrete region of an image) may be formed by combining received echo data in a manner that gives more weight to data that is likely to improve image quality, and/or discounting or ignoring data that is likely to detract from image quality (e.g., by introducing noise or by increasing point spread).
