The IRTIC participation focuses on tracking and guided 3D systems for Intraoperative Radiotherapy (RIO), integrating itself mainly in the sub-project S3 of the complete project. The main objective of this S3 Subproject is the study of the viability of the use of technologies that allow the guidance through image of the treatment applied to a patient. Particularly, the techniques employed will increase the safety with which intraoperative radiotherapy treatments are made, although, the technologies developed can have an interesting impact in other surgical specialisations.

For this the following specific goals are proposed:

• To study and to propose different positioning systems that allows locating and integrating in a single coordinate system different elements of the treatment scenario: patients, equipment, instruments and pre-and-intra operative image studies, thus, improving the decision making and documentation of the procedure.
• To evaluate the introduction of different image techniques in the treatment scenario, evaluating the difficulties of its use, its accuracy and its contribution to the process.
• To design and to propose techniques of multiorgan segmentation, of whole organs and of relevant structures for the treatment.
• To design techniques of image registration which are appropriate for connecting different image studies, both pre-and intra-operative, different modalities, considering the contribution of the positioning techniques of this process.
• The results of this project will allow the evaluation of the contribution of different techniques of intraoperative image, of the navigation systems and of the algorithms for registering and segmenting images to the RIO process. So far, none of them have been used in these type of surgical procedures, so it is a completely new project.

The project has received funding from the Ministry of Science and Innovation, in the context of the National Plan of Scientific Research, Technological Development and Innovation 2008-2001.
