Abstract: The invention relates to an ultrasound data visualization apparatus for visualizing ultrasound data showing an object during an interventional procedure. A reference image (65) and a current image (68) of the object are simultaneously displayed, wherein the current image corresponds to a current time interval and the reference image corresponds to a reference time interval and wherein the current time interval and the reference time interval correspond to different phases of the interventional procedure. The current image can be shown therefore with, for instance, a relatively high temporal resolution for allowing a user to observe detailed object changes, which may be caused by the interventional procedure, while an overview over different phases of the interventional procedure can still be provided, because also the reference image is displayed and can be used by a user for comparing the current image with the reference image.

Abstract: System (10) for determining a position of an interventional device (11) respective an image plane (12) defined by an ultrasound imaging probe (13). The position is determined based on ultrasound signals transmitted between the ultrasound imaging probe (13) and an ultrasound transducer (15) attached to the interventional device (11). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI). A position determination unit (PDU) computes a position (LAPTOFSmax, θIPA) of the ultrasound transducer (15) respective the image plane (12). The position determination unit (PDU) indicates the computed position (LAPTOFSmax, θIPA) in the reconstructed ultrasound image (RUI). The position determination unit (PDU) suppresses the indication of the computed position (LAPTOFSmax, θIPA) under specified conditions relating to the computed position (LAPTOFSmax, θIPA) and the ultrasound signals.

Abstract: A method for ultrasound image processing having steps of receiving sequences of ultrasound images imaging an anatomical feature of interest during two cardiac cycles one in the absence of, and the other in the presence of, an invasive medical device in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle. The invasive medical device may at least partially obscure the anatomical feature of interest for each ultrasound image of the further sequence. The location of the invasive medical device is tracked and isolated in the ultrasound image, and the isolated invasive medical device is inserted into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location. The method also controls a display device to display the first sequence of ultrasound images including the inserted invasive medical device.

Abstract: An ultrasound image processing apparatus includes an image processor arrangement that receives a plurality of ultrasound images. Each ultrasound image shows an invasive medical device relative to an anatomical feature during a cardiac cycle. At different phases of the cardiac cycle, the anatomical feature has a different shape. The ultrasound processing apparatus compiles groups of the ultrasound images with ultrasound images in each group belonging to the same phase of the cardiac cycle. The ultrasound image processing apparatus generates an augmented ultrasound image from one of the ultrasound images by removing a shadow region on the anatomical feature of interest caused by the invasive medical device based on a displacement of the invasive medical device.

Abstract: An ultrasound device comprises a transducer arrangement and an acoustically transmissive window over said arrangement, said window comprising an elastomer layer having conductive particles dispersed in the elastomer, the elastomer layer having a pressure-sensitive conductivity. An electroactive material actuator is provided for biasing the transducer arrangement towards the transmissive window. The electroactive material actuator is controlled in dependence on a measured pressure-sensitive conductivity. In this way, a feedback system is provided for controlling a contact pressure. The device can be implemented with low cost and with low power consumption.

Abstract: The invention relates to a spatial configuration determination apparatus for determining a spatial configuration in the surrounding of an ultrasound device, in particular, for determining the orientation of the ultrasound device and of an object in the surrounding of the ultrasound device with respect to each other. The ultrasound device is preferentially arranged at a tip (5) of a cardiac ablation catheter (4) such that, for instance, the orientation of the tip (5) relative to cardiac tissue can be determined. Motion data and/or distance data are determined in different directions from ultrasound data acquired by the ultrasound device, wherein the determined motion data and/or distance data are used for determining the spatial configuration. This allows determining, for instance, the orientation of a tip (5) of an ablation catheter (4) relative to cardiac tissue, without necessarily requiring further orientation determination means.

Abstract: The present invention relates to an ultrasound system. A first non-invasive ultrasound probe receives first ultrasound data having a first field of view and a second invasive ultrasound probe receives second ultrasound data having a second field of view which is different from the first field of view. A tracking unit determines tracking data including a position and orientation of the first non-invasive ultrasound probe relative to the second invasive ultrasound probe. A registration unit registers the second field of view into the first field of view based on the tracking data.
