Introduction 

Intensity Modulated Radiotherapy (IMRT) is a major recent advance in the field of radiotherapy. Although a great deal of effort has been invested in improving treatment planning and treatment delivery equipment, there is a very strong need for improving the accuracy, efficiency and the analysis methods in IMRT verification.

The InVoRad project addresses these needs by development of two accurate and efficient dose measurement systems for real time dosimetry:

q     Semiconductor diode based system for patient specific dosimetry in IMRT (Delta⁴), and

q     RADFET based detector line array for intracavity in vivo patient dosimetry.

InVoRad is an European Commission sponsored research project bringing together scientists and engineers from Clatterbridge Centre for Oncology (UK), City University London (UK), Tyndall National Institute (Ireland), and ScandiDos (Sweden) with complementary research, clinical and industrial competences.

The project is scheduled for completion in January 2006. Commercialisation activities are under way and will continue after the project completion.
