Methods based on magnetic resonance imaging for the measurement of three-dimensional distributions of radiation dose are highly developed. However, relatively little work has been done on optical computed tomography (OCT). This paper describes a new OCT scanner based on a broad beam light source and a two-dimensional charge-coupled device (CCD) detector. A(More)
X-ray tomography has not been widely used for the examination of plant roots in soil despite its non-destructive nature and ability to overcome the imaging constraints imposed by the soil medium. Some of the reasons for the restricted implementation of this technique have been the limited spatial resolution (Rosenfeld et al. 2002), limited sample size(More)
