3D Printed Phantoms for Testing, Evaluating, and Calibrating Optical Imaging Methods
- Summary
- Purdue University researchers have developed a method for fabricating phantoms for optical imaging that allows design of the material's optical properties (scatter and absorption). By using 3D printing with stereolithography, a water tight phantom with complex geometry and no air gaps can be made. The optical properties can be designed to match those of biological tissues. This method allows for the placement of complex inhomogeneities in a complex geometry, making it ideal for testing, evaluating, developing, and calibrating imaging methods and equipment.

- *Background
- Phantoms are objects that are scanned or imaged in the field of medical imaging to evaluate, analyze, and tune the performance of various imaging devices. Phantoms are more readily available and provide more consistent results than the use of a living subject or cadaver and limits exposure to the living. Most phantoms are made using injection mold methods, which limits the shape of phantoms to the mold geometry. Molds also make it very difficult or impossible to introduce complex inhomogeneities within the phantom.
