Abstract

A method for generating enhanced image data. First image data, for example CT image data, and second image data, for example CBCT image data is received. Data indicating a relationship between said first image data and said second image data is generated, for example in the form of a shading map. The generated data is applied to said second image data to generate enhanced image data.
