Figure 4b. Effects of an overlapping reconstruction interval. (a) Contiguous data set reconstructed with a section thickness and interval of 2.5 mm. Coronal reformatted image shows a jagged cortical contour due to stair-step artifact. (b) Overlapping data set reconstructed with a section thickness of 2.5 mm but with the interval decreased to 1.25 mm, an overlap of 50%. Such overlapping minimizes stair-step artifact and improves demonstration of a fracture of the right superior pubic ramus (arrowhead).
