The outlook for patients with localized prostate cancer is brighter than ever, thanks to a procedure that combines the exactness of computer-assisted planning with the precision of ultrasound-guided technology. Known as prostate radioactive seed implantation, this one-day surgical procedure places tiny radioactive seeds accurately within the confines of the prostate gland where they act to destroy cancerous cells while leaving nearby healthy tissue intact. 3, record 1, English, - radioactive%20seed

Le traitement du cancer de la prostate au moyen d'implants radioactifs permanents : caractérisation de la migration des sources et simulations par ordinateur. Ce traitement du cancer de la prostate consiste en l'implantation permanente de sources radioactives directement dans la glande. Une étape importante de la planification du traitement est l'élaboration du plan de chargement. Celui-ci établit le nombre et l'emplacement des grains radioactifs à l'intérieur de la prostate de façon à obtenir une couverture de dose optimum. Après l'intervention, et malgré de nombreuses précautions, les grains ne sont pas exactement à l'endroit planifié et la qualité du traitement s'en trouve altérée. Cet écart par rapport à la position planifiée est connu sous le nom de migration. Le premier volet de l'étude porte sur la migration des sources. Des quantités telles que l'angle d'insertion de l'aiguille, la courbure de la trajectoire des grains, le déplacement transverse et l'étirement sont mesurées sur 30 cas totalisant 1 200 sources. 1, record 1, French, - grain%20radioactif
