High resolution crossed-beam laser spectroscopy has been used to measure the isotope shifts and hyperfine parameters of nineteen transitions in atomic ruthenium. These results have been used in conjunction with four other existing transition measurements to determine accurate values for the change in mean-square charge radius between the isotopes of ruthenium. The new charge radii measurements exhibit up to an order of magnitude improvement in accuracy compared to the previously published results. These accurate charge radii systematics in ruthenium provide additional data for the interesting N=60 region of the nuclear chart. The transitions measured have been assessed in terms of their suitability for use in future collinear laser spectroscopy measurements of radioactive ruthenium isotopes. One transition in particular, the 349.8942nm Ocm-1 to 28571.890cm-1 transition, has the potential to be highly efficient.
