Abstract
Intensity standardization of MRI data sets aims at correcting scanner-dependent intensity variations. An automatic technique, called STI, which shares the simplicity and robustness of histogram-matching techniques, but also incorporates tissue spatial intensity information, has been discovered. The method comprises registering a medical image to a standard image; applying one or more masks to the medical and standard images for isolating certain specific image components; determining the most common intensity data pair between the medical and standard images for each isolated image component; calculating a formula that joins the most common intensity data pair of each image component; and interpolating an intensity data adjustment using the formula and applying it to the medical image data to generate a standardized version of the medical image.
