1. A computer implemented method for analysing images in a computer aided diagnosis system (CADx) to provide at least one of a first image analysis score and a second image analysis score for an image comprising;
receiving an input at the CADx system comprising at least one input image showing all or part of the lungs of a subject;
analysing the input to calculate a first interim image analysis value and a second interim image analysis value for the input;
processing the calculated interim values in the CADx system to generate corresponding first image analysis and second image analysis scores and outputting at least one of the first image analysis score and the second image analysis score for the subject; wherein the first image analysis score is a disease prediction score corresponding to a likelihood of the disease and the second image analysis score is at least one disease characterisation score corresponding to a likelihood of each of at least one disease characterisation, and
wherein all scores are processed by an output selector circuit which performs operations on the scores to produce the output of the CADx system, resulting in the disease prediction score and the disease characterisation score being output except when either: the disease prediction score means the disease characterisation score is not required, so only the disease prediction score is output or the disease prediction score and the disease characterisation score are not compatible, so only the disease prediction score is output.
