The present invention relates to a device () for modifying an imaging of a TEE probe in X-ray data, a medical imaging system () for modifying an imaging of a TEE probe in X-ray data, a method for modifying an imaging of a TEE probe in X-ray data, a computer program element for controlling such device () and a computer readable medium having stored such computer program element. The device () comprises an X-ray data provision unit (), a model provision unit (), a position locating unit (), and a processing unit (). The X-ray data provision unit () is configured to provide X-ray data comprising image data of a TEE probe. The model provision unit () is configured to provide model data of the TEE probe. The position locating unit () is configured to locate a position of the TEE probe in the X-ray data based on the model data of the TEE probe. The processing unit () is configured to define a region in a predetermined range adjacent to the TEE probe as reference area. The processing unit () is configured to process the X-ray data of the reference area into estimated X-ray data of a region occupied by the TEE probe. The processing unit () is configured to modify the X-ray data in the region occupied by the TEE probe based on the estimated X-ray data.

Device for modifying an imaging of a tee probe in X-ray data

A system for finding improved views includes a shape sensing optical fiber system disposed on or in a prosthesis to track the prosthesis in a volume. A real-time imaging system employs a non-ionizing radiation source to image the volume having the prosthesis and reference positions in the volume. A search program is stored in memory to search images of the real-time imaging system to identify the reference positions in the volume. An image processing device overlays shape sensing data and images from the real-time imaging system and computes an improved view in accordance with improved view parameters.

An medical viewing system () adapted for acquiring a first set of X-ray fluoroscopy images of an ultrasonic probe () of an echocardiography imaging device at two different viewing angles, wherein a processing unit () of the system is adapted for registering live echocardiography and live X-ray images based on the first set of X-ray fluoroscopy images, localizing cusp nadirs positions of a set of characteristic features () in the X-ray subsequent frames, establishing a set of markers to match the localized positions of the cusp nadirs characteristic features (), and determining an optimal viewing angle of the X-ray image acquisition device (), in which the markers of the second set of markers lie on a single line and are equidistant from each other in the X-ray field of view. This enables a precise alignment of the X-ray imaging device, especially for TAVR procedures.
