摘要： Concepts for the identification of a gain parameter value for ultrasound hemodynamic analysis are proposed. Overall, an output B-mode gain value may be determined which can be used to produce a B-mode ultrasound image having an optimized contrast-to-noise ratio in a region of interest of the ultrasound image. The global B-mode gain may be adjusted, resulting in an improvement of the contrast-to-noise ratio in the region of interest. Using the proposed concept(s), an output B-mode gain may be automatically generated which is suitable for hemodynamic analysis of a blood vessel of a subject, without the need for intervention by a skilled operator.

摘要： A device, system, and method is provided for detecting pain in a cardiac-related region of the body and determining whether that pain is cardiac or non-cardiac. The device, system, and method may include calculating or determining a first feature based on a variation in activity level and a variation in the detected heartrate measurement and a second feature based on a variation in the detected ECG features and a first feature and then subjecting at least the first feature and the second feature to a cardiac pain classifier to determine a cardiac classification.

摘要： There is a need for techniques to avoid or reduce motion artifacts in medical images. According to the invention, there is provided control circuitry for a medical imaging system. The control circuitry is configured to control the medical imaging system to provide synchronized display and nudging to provide a patient with information on the progress of a scan. In this way, patient anxiety may be reduced by providing the patient with a sense of time during the scan, leading to a reduction in motion artifacts.

摘要： There is provided a computer-implemented method (200) for obscuring one or more facial features of a subject in an image. A head of the subject is detected in the image (202) and a location of one or more facial features of the subject is identified in the image (204). A region of the image to modify is determined based on the location of the one or more facial features (206). The determined region comprises a part of the head on which the one or more facial features are located. The image within the determined region is modified to obscure the one or more facial features (208).

摘要： A diagnostic ultrasound system for carotid artery diagnosis has a two dimensional array probe with a low element count and relatively large element size which can cover an area of the carotid artery at its bifurcation. The elements are operated independently with no phasing, and detect Doppler flow spatially beneath each element. The system produces maps of carotid blood flow in two or three dimensions and can assemble an extended view of the flow by matching segments of the carotid flow as the probe is moved over the vessel. Once the carotid artery has been localized, the degree of stenosis is assessed by automated measurements of peak systolic velocity and blood flow turbulence.

摘要： The invention provides a method for guiding the acquisition of ultrasound data. The method begins by obtaining ultrasound data from a plurality of data acquisition planes and performing spatial registration of the data acquisition planes. A number of vessels are then identified in each data acquisition plane. A location of a vessel bifurcation is then identified based on the spatial registration of the data acquisition planes and the number of vessels in each data acquisition plane. A guidance instruction is generated based on the location of the vessel bifurcation, wherein the guidance instruction is adapted to indicate a location to obtain further ultrasound data.

摘要： The invention relates to a system, an ultrasound probe and a corresponding method for measuring arterial parameters using non-imaging ultrasound. The system comprises an acquisition unit for acquiring doppler ultrasound signal from a blood vessel and a processing unit for processing the acquired doppler ultrasound signal and to determine the changes in the blood vessel through the measurements of at least Peak Systolic Velocity (PSV) and Pulse Wave Velocity (PWV). The acquisition unit comprises an ultrasound probe having a plurality of transducer elements arranged in a grid configuration, and comprising a first probe (102a) and a second probe (102b) detachably connected to each other. In the split configuration the ultrasound probe is provided to measure the PWV globally between the carotid and femoral arteries, or the PSV and PWV locally and simultaneously. In the integrated configuration the PSV or PWV may be measured locally.
