1. A process for generating enhanced resolution images of fibrous tissue located within a portion of a body being sampled, said method including: i) accessing source data representing a distribution of said fibrous tissue orientations within each of a plurality of discrete sample imaging elements defined within said portion based on a first imaging resolution; ii) generating, based on said source data, streamline data representing a plurality of fibre tracks, each said fibre track representing an estimated path of fibres in said tissue within said portion; iii) generating an output matrix defining a plurality of discrete output imaging elements within said portion based on a second imaging resolution that provides higher imaging resolution than said first imaging resolution; iv) generating, for each said output imaging element, image data including intensity data representing a level of intensity based on a number of said fibre tracks at a location corresponding to said output imaging element; and v) generating display data for controlling a display device to display an enhanced image generated based on said image data.
