1. A method for assessing an imaged subject, the method comprising the steps of:

  • obtaining imaging data of said imaged subject, said imaging data being representative of an extensional feature of said imaged subject;

    applying direct quantitative analysis to said imaging data to determine at least one parameter value of said extensional feature, andgenerating an output signal representative of the determined parameter value of said extensional feature;

    the step of applying quantitative analysis further comprising the steps of selecting an imaging data set corresponding to a selected region of said imaged subject, identifying a spatially varying function, that is representative of the cross section of extensional feature in said imaging data set, the spatially varying function comprising non-circular functions and families of profiles, said profiles comprising Gaussian functions and ellipsoid functions and generating said at least one parameter value from the identified spatially varying function.
