Abstract
Various micro and nano-manufacturing techniques were investigated to create controlled flaws for X-ray computed tomography (XCT) phantoms. We explored the use of focused ion beam (FIB), laser micromachining, and projection photolithography with deep reactive ion etching (DRIE) to generate controlled pores from 100s of micrometers to a few micrometers in size. Principles of each technique, fabrication results, and calibration process for the created pores are discussed. We also discuss possible assembly techniques and some initial results. Example scanning electron microscope (SEM) and XCT measurements of the phantoms are shown.Proceedings Title
