The invention relates to a phantom which is intended for the quality control of a system used for the virtual simulation of a radiotherapy treatment, comprising a medical imaging device. The invention is characterised in that it comprises: a support case (1); a core (4) which is disposed inside the support case (1) and which consists of a plurality of elements (5, 6, 7, 8, 11, 12, 14, 15, 16, 17) having different shapes, dimensions and densities, the latter simulating the densities of different organs and media of the human body, two of the aforementioned elements (11, 12) comprising two truncated cones, with different densities, fitted one inside the other, at least one of said two elements not being completely symmetric in relation to the longitudinal axis thereof; balls (9, 10, 13) which are made from a non-radiotransparent material and which are disposed inside the core (4); and at least two removable lateral faces (18, 21) which are disposed opposite one another and which house metal wires defining geometric figures.
L'invention concerne un fantôme pour le contrôle qualité d'un système de simulation virtuelle d'un traitement de radiothérapie comportant un dispositif d'imagerie médicale, caractérisé en ce qu'il comporte : - un caisson support (1), - un noyau (4) disposé dans ledit caisson support (1) et constitué par une pluralité d'éléments (5, 6, 7, 8, 11, 12, 14, 15, 16, 17) de formes, dimensions et densités différentes, lesdites densités simulant les densités de divers organes et milieux du corps humain, deux de ces éléments (11, 12) étant constitués par deux troncs de pyramides de densités différentes emboîtés l'un dans l'autre, l'un d'entre eux au moins ne présentant pas une totale symétrie par rapport ô son axe longitudinal, - des billes (9, 10, 13), en un matériau non radiotransparent disposées dans ledit noyau (4), - au moins deux faces latérales amovibles (18, 21) opposées l'une ô l'autre renfermant des fils métalliques définissant des figures géométriques.
