Fig. 2From: High-throughput three-dimensional visualization of root system architecture of rice using X-ray computed tomographyInfluence of tube voltage and current on X-ray CT images, using a 4-week-old Kinandang Patong as the scanning subject. Scaled-up vertical slices are shown, using combinations of 125, 150, 175, 200, and 225 kV tube voltages, and 100, 200, 300, 400, and 500 μA tube currents. Numbers on the images indicate the contrast-to-noise ratioBack to article page
