Numerical image processing of two or more medical images to provide grayscale registration thereof is described, the numerical image processing algorithms being based at least in part on a model of medical image acquisition. The grayscale registered temporal images may then be displayed for visual comparison by a clinician and/or further processed by a computer-aided diagnosis (CAD) system for detection of medical abnormalities therein. A parametric method includes spatially registering two images and performing gray scale registration of the images. A parametric transform model, e.g., analog to analog, digital to digital, analog to digital, or digital to analog model, is selected based on the image acquisition method(s) of the images, i.e., digital or analog/film. Gray scale registration involves generating a joint pixel value histogram from the two images, statistically fitting parameters of the transform model to the joint histogram, generating a lookup table, and using the lookup table to transform and register pixel values of one image to the pixel values of the other image. The models take into account the most relevant image acquisition parameters that influence pixel value differences between images, e.g., tissue compression, incident radiation intensity, exposure time, film and digitizer characteristic curves for analog image, and digital detector response for digital image. The method facilitates temporal comparisons of medical images such as mammograms and/or comparisons of analog with digital images.

The guard band between two carriers of the same or different operators is reduced or dynamically adjusted by initiating a dynamic change request of the guard band between the two carriers to allow for flexible spectrum use by adjusting the tolerable guard band overlap. The data is distributed or positioned in the carrier spectrum band as a function of the Quality of Service so that the lowest Quality of Service constrained data are positioned at the edges of the carrier spectrum band and the highest Quality of Service constrained data are positioned in the middle of the carrier spectrum band to minimize any impact from the increased adjacent channel interference due to the guard band overlap and narrower guard band.
