Abstract: In a diagnostic scanner for shear wave elastography imaging an ultrasound exposure safety processoris is configured for spatially relating respective definitions of an imaging zone (324), and an extended dead-tissue zone (312) that includes both a dead-tissue zone and a surrounding margin. Based on whether a push pulse focus (344, 348, 352) is to be within the extended dead-tissue zone, the processor automatically decides as to a level of acoustic power with which the pulse is to be produced. If it is to be within, the pulse may be produced with a mechanical index, a thermal index, and/or a spatial-peak-temporal-average intensity that exceeds respectively 1.9, 6.0 and 720 milliwatts per square centimeter. The imaging zone may be definable interactively so as to dynamically trigger the deciding and the producing, with optimal push pulse settings being dynamically derived automatically, without the need for user intervention. A display of multiple push pulse sites (344-352) allows user manipulation of spatial definition indicia (336) to dynamically control displacement tracking.

Based on whether a push pulse focus is to be within the extended dead-tissue zone, the processor automatically decides a level of acoustic power with which the pulse is to be produced. If the pulse focus is to be within the extended dead-tissue zone, the pulse may be produced with a mechanical index (MI), a thermal index (TI), and/or a spatial-peak-temporal-average intensity (IspTA) that exceeds respectively 1.9, 6.0 and 720 milliwatts per square centimeter. The imaging zone may be definable interactively to dynamically trigger the deciding and the producing, with push pulse settings being dynamically derived automatically. A display of multiple push pulse sites allows user manipulation of spatial definition indicia to dynamically control displacement tracking.

Abstract: Depiction, within a single imaging modality, of an intervention device and body tissue surrounding the device, is improved by interrogating a subject that includes the intervention device and the tissue. An image is created using, for a parameter, a value, of the parameter (160), better suited to one or the other of a device region depicting the intervention device and a tissue region depicting the tissue. The value is used to yield respectively either a first image (152) or a second image (154). Respective presets may correspondingly have different values for the parameter. From jointly the first image and the second image which are both of the single modality, a combination is formed that is an image of the intervention device depicted as surrounded by the tissue. The combinations may be formed dynamically and ongoingly. An apparatus for the improved depiction may be configured for the use of the parameter in a stage prior to image processing conducted on a scan-converted image (146) if such image processing is employed.

Abstract: In some embodiments, ultrasound receive beamforming yields beamformed samples, based upon which spatially intermediate pixels (232, 242, 244) are dynamically reconstructed. The samples have been correspondingly derived from acquisition through respectively different acoustic windows (218, 220). The reconstructing is further based on temporal weighting of the samples. In some embodiments, the sampling is via synchronized ultrasound phased-array data acquisition from a pair of side-by-side, spaced apart (211) acoustic windows respectively facing opposite sides of a central region (244) to be imaged. In particular, the pair is used interleavingly to dynamically scan jointly in a single lateral direction in imaging the region. The acquisition in the scan is, along a synchronization line (222) extending laterally across the region, monotonically progressive in that direction. Rotational scans respectively from the window pair are synchronizable into a composite scan of a moving object. The synchronization line (222) can be defined by the focuses of the transmits. The progression may strictly increase.

Abstract: The present invention relates to an ultrasound elastography system (10) for providing an elastography measurement result of an anatomical site (32) a corresponding method. The system (10) is configured to visualize a suitability for shear wave elastography of the region of interest (33) to the user within the ultrasound image (52) and/or to recommend an elastography acquisition plane (48, 50) for conducting shear wave elastography to the user. By this, proper selection of a location for an elastography measurement may be supported.
