1. A system for analyzing image data, comprising: an input for receiving the image data, the image data representing image intensities of an image volume, the image intensities having a signal dynamic range; an analysis subsystem for: i) accessing display data defining a set of display settings for display of the image volume, each one of the set of display settings causing a different sub-range of the signal dynamic range to be mapped to a display dynamic range during the display, ii) analyzing the image data to identify, for each one of the set of display settings, a region of the image volume which comprises image intensities within the respective sub-range, thereby identifying a set of regions of interest; and iii) generating analysis data identifying the set of regions of interest.
