7. A method for modifying an imaging of a transesophageal echocardiography (TEE) probe in X-ray data, the method comprising:
a) providing the X-ray data comprising image data of a TEE probe,
b) providing model data of the TEE probe,
c) locating a position of the TEE probe in the X-ray data based on the model data of the TEE probe,
d) defining a region in a predetermined range adjacent to the TEE probe as a reference area,
e) processing X-ray data of the reference area into estimated X-ray data of a region occupied by the TEE probe,
f) temporarily hiding the TEE probe, or translucently or transparently imaging the TEE probe and/or reducing to an outline of the TEE probe with a color and/or grey scale to indicate a parameter of interest based on the estimated X-ray data during a C-arm rotational acquisition such that the TEE probe is not present in a 3D reconstructed image volume generated after the C-arm rotational acquisition,
g). assigning an intensity gradient to the estimated X-ray data of the region occupied by the TEE probe.
