An application of HDR in medical imaging

We describe a solution aimed at overcoming dynamic range problems in the visualization of medical images. We \ufb01rst analyze the speci\ufb01c requirements for a high dynamic range (HDR) display that should operate in the medical (diagnostic) context, and the procedures that are followed in a laboratory of the US Food and Drug Administration to evaluate such a display. We then describe in some detail an LCD composed of two stacked liquid crystal panels, a prototype of which is presently being developed at Barco
