Review of Phantoms for Tomographic imaging, with Applications towards Diffuse Spectroscopy Within Clinical Imaging Systems

摘要

Near infrared spectroscopy with diffuse light has been used within magnetic resonance imaging for several years now. The calibration of these hybrid systems requires sophisticated phantoms which have both NIR and MR characteristics, and allow validation of all the resolution, contrast, geometry and anthropomorphic characteristics of the systems and their applications. This paper reviews the range of uses of phantoms in MR and tomography imaging, and discusses key areas of development in NIR phantoms, and then some gelatin based phantoms which have been used in the hybrid system application of breast cancer imaging.
