[Rayonnements ionisants et medecine : besoins metrologiques.]
L'utilisation des Rayonnements Ionisants en Médecine souligne l'importance de la Métrologie pour l'étude des phénomènes biologiques et la mise en œuvre d'examens ou de techniques de traitement élaborés. En particulier, la Radiothérapie, contribuant largement à la guérison des cancers, exige le plus haut niveau d'exactitude pour optimiser la dose absorbée délivrée aux tissus tumoraux et aux tissus sains environnants. La valeur maximale recommandée pour l'incertitude type combinée dans la détermination de la dose absorbée est de 3,5 %, à la limite des possibilités actuelles de la dosimétrie et des modalités de traitement. Une amélioration des techniques et des appareillages, des Laboratoires Primaires au milieu hospitalier est donc indispensable.
The use of Ionizing Radiation in Medicine emphasizes the importance of Metrology for the study of biological phenomena and the development of high standard examination or treatment techniques. In particular, Radiotherapy, an important tool for cancer cure, requires the highest level of accuracy to optimize the absorbed doses delivered to the tumour and the surrounding normal tissues. The recommended upper value for the combined standard uncertainty on absorbed dose is 3.5%, lying close to or just beyond the present possibilities of radiation dosimetry and treatment delivery. It should act as a stimulus for improving the techniques and equipment from the Standards Laboratories to the clinical environment.
