Visualization method and imaging system

A method is provided for visualization of hollow organs of a patient. An x-ray image dataset of the hollow organ is recorded and registered. A number of individual x-ray images are recorded during a movement of an instrument with a data capture unit through the hollow organ, with each individual x-ray image featuring time information. Datasets of a data capture unit of an instrument is recorded during the movement of the instrument, with each dataset featuring time information. Position of the instrument is determined based on the individual x-ray images by an image recognition algorithm. The datasets of the data capture unit and the position of the instrument is spatially assigned based on the time information of the datasets of the data capture unit and the individual x-ray images. The datasets of the data capture unit is jointly displayed with the x-ray image dataset.
