Determination of 3D dose distribution by PAG and Monte-Carlo simulations

Le rôle des simulations numériques Monte Carlo dans les domaines associés à la physique des rayonnements ionisants

“…Les études ont porté initialement sur le développement des calculs dosimétriques, tant par l'élargissement des connaissances sur les paramètres physiques des faisceaux d'irradiation que par l'amélioration des fantômes numériques et des dosimètres utilisés pour le calcul de la distribution 3D de la dose (Guillerminet, 2003 ;Guillerminet et al, 2005Guillerminet et al, , 2003Guillerminet et al, , 2001. Des efforts importants ont été déployés pour simuler correctement la tête de l'accélérateur SATURNE43 (Fig.…”

Calibration of laser tomography as a new optical diagnostic tool applied to dosimetric polymer gels

“…Thereby the particular case of irradiated tissues near metallic prosthesis cannot be investigated with this technique [7]. The present work is based on the experience on the polymer gel [8,9] pre-acquired at the laboratory in collaboration with the CTU of Prague.The first results have been obtained by using a method based on the scattering of coherent light at 90°.The polymer gel [2,3,10,11] developed for this application is very sensible to both oxygen and irradiation [3]. Without oxygen, the irradiation induces the polymerisation of monomers and the reticulation of the polymers formed.…”
