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.

An image registration systemfor registering a live stream of ultrasound imagesof a beamforming ultrasound probewith an X-ray imageis described. The image registrationsystem identifies, from the X-ray image, the position of a medical devicerepresented in the X-ray image; and determines, based on ultrasound signals transmitted between the beamforming ultrasound probeand an ultrasound transducerdisposed on the medical device, a location of the ultrasound transducerrespective the beamforming ultrasound probe. Each ultrasound image from the live streamis registered with the X-rayimage based on the identified position of the medical device. The registration includes determining an offset from said identified position that is based on i) a predetermined spatial relationship of the ultrasound transducerrespective the medical deviceand ii) the determined location of the ultrasound transducerrespective the beamforming ultrasound probe

An energy application apparatus applies energy to an object. An energy application unit applies energy to the object, wherein the energy application unit is adapted to use electrical current for applying the energy. A current measuring unit measures the electrical current used by the energy application unit and provides a signal being indicative of whether the energy is applied to the object based on the measured electrical current. The signal can be used by, for instance, a monitoring unit and/or a display unit for using and/or indicating the information whether energy is actually applied or not, without requiring a direct communication between the energy application unit and the monitoring unit and/or the display unit.
