Figure 3
Projection images acquired by the CMOS camera at the end of the beamline endstation. (a) Image acquired while the liquid-jet chip was moved out of the beam (sample-out). (b) Image acquired with the liquid-jet chip in the measurement position (sample-in). (c) Image derived from the previous two as the (sample-in)/(sample-out) ratio. The four ROIs are shown: A and B are the background ROIs for the sample-out and sample-in images, respectively, usually taken in the chip shadow; C is the signal ROI; D is the normalization ROI.
