Abstract

A simple and easy to use method is proposed for standardizing NIR imaging systems for differences among detectors in the charge‐coupled device (CCD) array and illumination unevenness. The standardization equations are then used to pre‐treat NIR image data to reduce the systematic errors introduced by a line‐scan NIR imaging system. The method requires only easily available homogeneous standards with relatively uniform spectral response. The effectiveness of the standardization in reducing the pixel‐to‐pixel biases and other systematic effects is illustrated with examples, and the improved sensitivity in results obtained from a multivariate image analysis (MIA) based on multi‐way principal component analysis (MPCA) is demonstrated.

My introduction to NMR began as a student in the laboratory of Sir Peter Mansfield in 1973. At that time a few initial reports had started to appear that were to be significant for the early development of MR imaging. Dr. Paul Lauterbur had demonstrated that NMR could be used for mapping spin densit
