"A computer tomograph (CT) with special software solutions is helping to improve the planning of radiotherapy, thus making cancer treatment more effective. Radiotherapy aims to irradiate tumors as precisely as possible. To make this possible, radiotherapists first make CT images to determine the exact size and location of the area to be irradiated. However, image quality is impaired by metal implants and breathing movements, thus making therapy planning more difficult. To counter these problems, the Siemens tomograph SOMATOM Definition AS Open RT Pro edition is equipped with software that offsets the effects of such interference so that the radiation can be more precisely targeted. The device has been equipped with a number of special features to enhance it for use in radiotherapy."^^<http://www.w3.org/2001/XMLSchema#string>
