title: Erratum: 0.5 gigapixel microscopy using a flatbed scanner: erratum.
abstract: When one uses USAF target to calibrate the resolution of an imaging system, the periodicity of the smallest resolvable line should be used to define the limit. However, in the original paper, the line width of the resolution target was used to characterize the resolution of our microscope system, resulting in an overestimation of the performance of the imaging system. In this erratum, we correct the parts that state incorrect resolution and also re-evaluate the performance of our micoscope.[This corrects the article on p. 1 in vol. 5, PMID: 24466471.].
