Comparison of Two Bioimaging Techniques (IMAGE) Institute for Basic Science Caption This is line-temporal focusing microscopy (LTFM) and point scanning microscopy (PSM). IBS researchers increased LTFM resolution, by restoring the circular symmetry of the LTFM beam. Images of a fluorescently-labelled mouse lung slice show that the improved LTFM achieves a higher resolution than PSM: a result never reached before.
