The present invention relates to a design idea of a radioactive seed implanting template and a manufacturing method thereof. The manufacturing method comprises the following steps: (1) collecting image data about tumor portions of patients by using a scanning system (2) a curing plan system reading the image data obtained in step (1) and drawing up a radioactive seed implanting plan according to the image data, to obtain picture data comprising locations, quantity and directions of needle passages and seed distribution information (3) an image control system and a template design system processing the picture data on the basis of the picture data comprising locations, quantity and directions of needle passages and seed distribution information in step (2), and performing design to obtain a template digital model having patient facial morphology information, and locations, quantity and direction distribution information of needle passages and (4) a template forming system forming a physical object by using the template digital model in step (3) as the template, to obtain a physical radioactive seed implanting template after preparation. The template of the present invention is accurate and stable in positioning, and basically eliminates the setup errors.La présente invention concerne une idée de conception dun gabarit dimplantation de semence radioactive et son procédé de fabrication. Le procédé de fabrication comprend les étapes suivantes : (1) la collecte de données dimage concernant des parties de tumeur de patients par utilisation dun système de balayage (2) la lecture, par un système de plan de guérison, des données dimage obtenues dans létape (1) et lélaboration, par ce système, dun plan dimplantation de semence radioactive selon les données dimage, pour obtenir des données dimage comprenant des informations demplacement, de quantité et de directions de passages daiguille et de distribution de semence (3) le traitement, par un système de commande dimage et un
