A comprehensive software toolkit for external beam radiotherapy.


As your versatile and intuitive assistant, ProSoma® accompanies you during the whole RT process. It facilitates decision making no matter if simple palliative or complex IMRT treatments are planned. The software's rich functionality ranges from virtual simulation, contouring, deformable registration, and adaptive RT, to dose evaluation and portal/IGRT verification. ProSoma's imaging tools are unique on the market. Due to its unmatched connectivity, it is regularly the link between all the many and varied systems typically present in a radiotherapy department. In addition, ProSoma's database server acts as a DICOM archive implementing dedicated requirements that are faced in a specialised RT department and not addressed by standard radiology PACS systems. To allow an easy start with the software, ProSoma offers a workflow wizard that guides you through the most important working procedures.

The ProSoma system is composed of a set of core functions that constitute the base of all further functionality and several specialised modules designed for the individual tasks of the RT procedure. Separate licenses are available for the system's RT modules to match the individual needs of any RT department. Furthermore, it is possible to restrict ProSoma to a pure reviewing station. In this case RT structures/plans/doses can be loaded into the system but editing functions are disabled.

ProSoma Base Functionality

External Interfaces:

  • Unparalleled connectivity supporting all DICOM image and RT formats
  • System independent of scanner, TPS, EPID or R&V system
  • Interface to laser systems and block cutters

Database + client/server:

  • Client/server architecture
  • Floating campus license
  • Conversion of any external document (doc, pdf, xls, images etc.) into a DICOM object and import into the database
  • Automatically generate DRR images based on received RT plan objects and CT data
  • DICOM forward functionality allows resending any incoming DICOM traffic to an external DICOM node, e.g. to the clinic PACS
