An optical modeling process for facial regions and other body surfaces has been developed. The body part in question is digitized using optical 3-D metrology to obtain a comprehensive dataset. The data is then prepared for further use by smoothing the point clusters. The radiophysically significant position of the radioactive material, e. g., seeds, aluminum tubes, etc., can be accurately determined using CAD modeling. Subsequently, a rapid prototyping process (fused deposition modeling [FDM]) is used to implement the CAD model directly in order to create a radiation applicator that can be used in practice. Biologically compatible polycarbonate can be used for this purpose.
已经开发出一种用于面部区域和其他身体表面的光学建模方法。使用光学三维计量技术对面部区域进行数字化处理，以获得全面的数据集。然后，通过平滑点云对数据进行预处理，以便进一步使用。通过CAD建模，可以精确确定放射性物质（如种子、铝管等）的放射物理显著位置。随后，使用快速成型工艺（熔融沉积成型[FDM]）直接实现CAD模型，以制造出可实际应用的放射施源器。为此可使用生物相容性聚碳酸酯。
