  • Modelling of the action of an optical fiber in photodynamic therapy treatment, and assistance in the planning of said treatment
    Patent number: 10204206
    Abstract: A method (200) for planning of a treatment with photodynamic therapy for a patient includes performing a measurement (230) of the volume of the treatment area by volume reconstruction from digital processing of contours inputted directly into a series of digital images of the area being treated, then determining (250) by calculating the number of optical fibers used, their position relative to the brachytherapy grid and their insertion length which optimizes the correspondence of a total theoretical action volume calculated with the measured volume of the treatment area. The total theoretical action volume is calculated based on the position of each fiber, and an elementary theoretical action volume of a fiber corresponding to the volume of a cylinder with predetermined action radius R, and height corresponding to the insertion length of the fiber.
