The use of standard CT scanners in Radiation Treatment Planning environments requires a higher geometric accuracy of anatomical data.

For the Siemens SOMATOM Emotion CT systems, a dedicated RTP package (including both hardware and software components) will be offered and provides the following features:

* improved gantry tilt accuracy

* reduced table top deflection

* externally adjustable gantry laserlights

* increased tube positioning accuracy

* simplified horizontal positioning of the table

* optimized field coverage using extended Field of View

Radiation Treatment Planning (RTP) Package will be used to prepare geometric and anatomical data, which may assist the physician with proposed external beam radiotherapy treatment planning.

Indications for use as stated in the FDA summary.
