  • Udo Jochen Birk, et al., "Correction for specimen movement and rotation errors for in-vivo Optical Projection Tomography." Optical projection tomography (OPT) allows for non-invasive imaging combined with the specificity of fluorescence labeling for imaging of embryos and small animals, however such measurements have traditionally been limited to fixed, non-living samples. This paper reports on novel post-processing mathematical methods to correct for sample drift and mechanical movements and thus extend the technique to living samples.

  • Kengyeh K. Chu, et al., "Practical implementation of log-scale active illumination microscopy." Active illumination microscopy (AIM) is a novel method of improving dynamic range in scanning microscopes using real-time feedback to control illumination power on a sub-pixel time scale. In this paper, a detailed theoretical and computational analysis of the influence of noise on active illumination feedback is presented, along with imaging examples illustrating the benefits of AIM in two-photon microscopy.

  • Rickson C. Mesquita, et al., "Resting state functional connectivity of the whole head with near-infrared spectroscopy." Newly available techniques employing near-infrared spectroscopy (NIRS) for monitoring brain function are non-invasive, inexpensive, portable, and have higher temporal resolution than standard functional magnetic resonance imaging (fMRI). This paper reports on the use of whole-head NIRS measurements for monitoring baseline fluctuations of cortical hemodynamics in human subjects, and analysis of their spatiotemporal correlations.

  • K. Passler, et al., "Scanning acoustic-photoacoustic microscopy using axicon transducers." Photoacostic microscopy and classical ultrasound imaging provide complementary information about specimens due to their different (optical versus acoustic) sources of contrast. This paper reports a novel approach to combine both techniqu
