Abstract
A two-dimensional or three-dimensional imaging of a target region in a hollow organ is provided. A two- or three-dimensional reconstruction image dataset is reconstructed from two-dimensional images from the inside of the hollow organ that are recorded by via a rotating image recording device and displayed, with images covering the entire target region being recorded during a partial rotation of the image recording device through a rotation angle.

A method for two-dimensional or three-dimensional imaging of a target region of interest in a hollow organ, comprising:
- recording a reconstruction image dataset from two-dimensional images from the inside of the hollow organ during a partial rotation of a single rotating image recording device through a rotation angle, the rotation angle less than 360°, images of the entire target region are recorded during the partial rotation;
- and
- displaying the reconstruction image dataset.
A method for two-dimensional or three-dimensional imaging of a target region of interest in a hollow organ, comprising:
- displaying a before-image dataset of the hollow organ registered with the coordinate system of a navigation system for determining a position and an orientation of the image recording device;
- recording a reconstruction image dataset in real time from two-dimensional images from the inside of the hollow organ during a partial rotation of a single rotating image recording device through a rotation angle, the rotation angle less than 360°, images of the entire target region are recorded during the partial rotation;
- and
- displaying the reconstruction image dataset,
- wherein the target region is defined by a user using the display of the before-image dataset.
A medical examination and treatment system, comprising:
- a catheter to be introduced into a hollow organ and has a single rotatable image recording device;
- and
- a control device that controlling the image recording device such that the image recoding device executes a partial rotation through a specific rotation angle, the specific-rotation angle less than 360°.
