Advances in 3D rapid-prototyping printers, 3D modeling software, and casting techniques allow for the fabrication of cost-effective, custom components in gamma-ray and x-ray imaging systems. Applications extend to new fabrication methods for custom collimators, pinholes, calibration and resolution phantoms, mounting and shielding components, and imaging apertures. Details of the fabrication process for these components are presented, specifically the 3D printing process, cold casting with a tungsten epoxy, and lost-wax casting in platinum.
3D快速成型打印机、3D建模软件和铸造技术的进步使得在伽马射线和X射线成像系统中制造具有成本效益的定制部件成为可能。其应用扩展到定制准直器、针孔、校准和分辨率体模、安装和屏蔽部件以及成像孔径的新制造方法。本文介绍了这些部件的制造过程细节，特别是3D打印过程、钨环氧树脂冷铸以及铂失蜡铸造。
