ROMERO, P. et al. Clinical impact of image guided radiotherapy. Anales Sis San Navarra [online]. 2009, vol.32, suppl.2, pp.33-37. ISSN 1137-6627.

Image guided radiotherapy (IGR) is a concept that encompasses the most modern way of administering radiotherapy treatment. The aim is to maximise the dose deposited in the target volume, minimising the dose in healthy organs. This would not be possible without the continuous development of technology and software, above all in the following areas: deformable image registration, replanning new treatments, real time image and calculation of accumulated dose. While the clinical impact is evident, little is said about the impact on the reorganisation of the Radiotherapy Oncology services. IGR supposes training all team members involved, with a training and a starting period. With the experience acquired, the time dedicated to each patient (in all stages of treatment: simulation, planning, starting out, systems for verifying position, on-line, off-line corrections, replanning, periodic clinical controls) is far higher than that required in conventional radiotherapy, which gives rise to new responsibilities and roles.
