OBJECTIVE The introduction of image-guided radiotherapy (IGRT) has changed the workflow in radiation oncology more dramatically than any other innovation in the last decades. METHODS Imaging for treatment planning before the initiation of the radiotherapy series does not take alterations in patient anatomy and organ movement into account. METHODS The principle of IGRT is the temporal and spatial connection of imaging in the treatment position immediately before radiation treatment. The actual position and the target position are compared using cone-beam computed tomography (CT) or stereotactic ultrasound. METHODS The IGRT procedure allows a reduction of the safety margins and dose to normal tissue without an increase in risk of local recurrence. RESULTS In the future the linear treatment chain in radiation oncology will be developed based on the closed-loop feedback principle. CONCLUSIONS The IGRT procedure is increasingly being used especially for high precision radiotherapy, e.g. for prostate or brain tumors.

D016634	Radiosurgery	A radiological stereotactic technique developed for cutting or destroying tissue by high doses of radiation in place of surgical incisions. It was originally developed for neurosurgery on structures in the brain and its use gradually spread to radiation surgery on extracranial structures as well. The usual rigid needles or probes of stereotactic surgery are replaced with beams of ionizing radiation directed toward a target so as to achieve local tissue destruction.

D021621	Imaging, Three-Dimensional	The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
