PHANTOM WHICH IS INTENDED FOR THE QUALITY CONTROL OF A VIRTUAL RADIOTHERAPY TREATMENT SIMULATION SYSTEM

摘要

The invention relates to a phantom for the quality control of a virtual simulation system of a radiotherapy treatment comprising a medical imaging device, characterized in that it comprises: - a support box (1), - a core (4) disposed in said support box (1) and constituted by a plurality of elements (5, 6, 7, 8, 11, 12, 14, 15, 16, 17) of different shapes, dimensions and densities, said densities simulating the densities of various organs and environments of the human body, two of these elements (11, 12) being constituted by two trunks of pyramids of different densities nested one inside the other, at least one of them not having a complete symmetry with respect to its longitudinal axis, - balls (9, 10, 13) of a non-radiolucent material arranged in said core (4), - at least two opposing lateral removable faces (18, 21) l one of the other enclosing metal wires defining geometric figures ues.
