1. A method comprising:
providing a server computer including a graphics processing unit, where the server computer:
a) receives a 3-D volumetric image reconstructed from a plurality of measured 2-D projection images;
b) computes three or more generated 2-D projection images based on three or more 3-D volumetric image viewing directions, where a first viewing direction is given by .theta.0, where the first viewing direction is based on user input, where a second viewing direction is given by .theta.1, where .theta.1 is selected according to a periodic continuous mathematical function (v(t)), where v(t)=normalize (z+A sin(ωtx)), where normalize (v) is v/lvl, t is time, ω is 2 π f, f is frequency and A is Amplitude, where a third viewing direction is given by .theta.2, where .theta.2 is selected according to the periodic continuous mathematical function; and
c) sends the three or more generated 2-D projection images and a viewing instruction adapted for display to a remote device, where the viewing instruction specifies an order of display of the three or more generated 2-D projection images for display on the remote device.
