Document Type and Number:
WIPO Patent Application WO/2024/011452
Kind Code:
A1
Abstract:
The present invention relates to the field of medical materials. Provided in the present invention are a method for preparing a thin film and the use of the thin film. The method for preparing the thin film comprises a step of preparing a functional layer, involving: uniformly mixing a dispersant, a curing agent and a radioactive long-afterglow luminescent material in a mass ratio of (200-2000):(6-240):1 to obtain a mixture; pouring the mixture into a flat-bottomed container, and performing vacuumizing in a vacuum drying box; and curing the vacuumized mixture to obtain a functional layer. The functional layer prepared by the method for preparing the thin film provided by the present invention comprises the radioactive long-afterglow luminescent material, which can replace an EBT film to obtain two-dimensional dose distributions in radiotherapy plans and obtain a wide linearity range. Moreover, the thin film can be worn on the human body, which improves the accuracy of the dose distributions in the therapy plans and the dose distributions actually accepted by a target.
