1. A method for quality control in image space for processing with an input data set, the method comprising: providing an image object and the input data set, the image object including a plurality of voxels; determining a data model from the image object; determining a cumulative distribution function (CDF) for the input data set from the data model and the input data set based on a plurality of projections; transforming the CDF to an image cumulative distribution function (ICDF) in image space, the ICDF representing a number of standard deviations associated with each voxel of the image object; and displaying an output of the ICDF.
