    Abstract: The invention relates to an inductive disturbance reduction device (18) for reducing an inductive disturbance of a signal like an ultrasound signal to be transmitted via first connection conductors (25, 26) of an electrical connector (11), which is caused when ablation current flows through a second connection conductor (24) of the electrical connector. The inductive disturbance reduction device is adapted to induce a voltage, which at least partly compensates a voltage induced in the electrical connector, in order to reduce the inductive disturbance in the signals to be transmitted via the first connection conductors of the electrical connector. Since the inductive disturbance is reduced, a high quality electrical connection can be provided, without necessarily using, for instance, a technically relatively complex and expensive coaxial connector. The inductive disturbance reduction device may be integrated, for instance, in a part of the electrical connector or in a cable.

    Abstract: The invention relates to a contact determination apparatus for determining a degree of contact between a device (2) and a moving object (3), wherein the contact determination apparatus comprises a motion distribution providing unit for providing a motion distribution being indicative of motion in the surrounding of the device and a contact determination unit (14) for determining a degree of contact between the device and the object based on the provided motion distribution. Since the degree of contact between the device and the object is determined based on the provided motion distribution and not simply based on, for instance, a peak of an A-mode signal, the determination of the degree of contact can be less disturbed by artifacts like ring-down artifacts or by blood scattering, if the object is, for instance, tissue. This can lead to a more accurate determination of the degree of contact.

    Abstract: The present invention relates to a monitoring apparatus (100, 200) for monitoring a structural change in an object (280, 340), such as a heart wall tissue. Tissue at first and second locations exhibits first and second velocities. The monitoring apparatus (100, 200) comprises an ultrasound signal providing unit for providing ultrasound signals of the object (280, 340) for different times. The monitoring apparatus (100, 200) further comprises a discontinuity determination unit (120, 220) for determining a discontinuity of the first and second velocities based at least in part on a change in time of tissue velocity differences and of tissue velocity sums. From the discontinuity an ablation depth can be determined, which is an important parameter while performing an ablation procedure. For example, it can be used for determining the progress of ablation within the object and for determining when the ablation has reached a desired dimension.

    Abstract: The invention relates to an imaging system for imaging a periodically moving object. An assigning unit (18) assigns ultrasound signals like A-lines to motion phases based on a provided phase signal,wherein an ultrasound images generation unit (19) generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. The ultrasound images are temporally consecutively displayed on a display unit (21) for showing the periodic movement of the object (24).The resulting dynamic, movie-like image of the object allows a user like a physician to more reliably determine properties of the object like a thickness of a tissue wall, in particular, during an ablation procedure. The imaging system is therefore particularly useful for monitoring cardiac ablation procedures.

A selecting unit (20) is used to select an ultrasound image from the generated ultrasound images, wherein a display unit (21) displays the selected ultrasound image. The selected ultrasound image corresponds therefore to a single motion phase only such that motion artifacts in the displayed ultrasound image are reduced. The imaging system is particularly useful for, for instance, monitoring cardiac ablation procedures.

    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.
