Abstract
Since the discovery of X-ray by Röntgen in 1895, the technological evolution of radiation therapy increased swiftly. However, the philosophy remained always the same: delivering higher radiation dose to the target volume while decreasing the dose to the organ at risk. Since the beginning of the 1990s, with conformal radiation therapy development (3DCT), differents techniques appeared. Some of them are derived from 3DCT, such as intensity-modulated radiation therapy, arctherapy, Tomotherapy™, or techniques using gating approach for breath holding. In the frame of stereotactic radiation therapy, the GammaKnife™ is already used since 20 years, while new concepts, based on a robotic approach (CyberKnife™), are now available for treatment. Brachytherapy also took advantage from the technological evolution with the new approaches. In the frame of heavy ions, hadrontherapy represents an interesting technique dedicated to special clinical situations including pediatric tumors. In this article, we report an analysis of the technological evolution of radiation therapy.
Résumé
Depuis la découverte des rayons X(RX) par Röntgen, en 1895, á nos jours, l’évolution technologique de la radiothérapie n’a cessé de s’accélérer. Cependant, la philosophie est toujours restée la même: délivrer une forte dose au volume cible tout en limitant la dose aux organes á risque. Depuis le début des années 1990, avec l’aveènement de la radiothérapie conformationnelle (RC3D), différentes techniques se sont développées. Certaines sont dérivées de la RC3D comme la RC3D avec modulation d’intensité, l’arcthérapie, la Tomothérapie™ ou les techniques d’asservissement respiratoire. Dans le domaine de la radiothérapie stéréotaxique, le GammaKnife™ est utilisé depuis une vingtaine d’annes, alors que de nouveaux concepts basés sur une approche robotique de l’irradiation (CyberKnife™) sont á présent utilisés. Aux côtés de la radiothérapie externe, la curiethérapie de nouvelle génération a, elle aussi, pu bénéficier de progrès technologiques majeurs. Dans le domaine des ions lourds, l’hadronthérapie représente une technique adaptée á des situations cliniques complexes, notamment en pédiatrie. Nous présentons ici une analyse de l’évolution technologique de la radiothérapie.
