  • Publication number: 20120208184
    Abstract: In accordance with preferred embodiments of the present invention, a method for imaging tissue, for example, includes the steps of mounting the tissue on a computer controlled stage of a microscope, determining volumetric imaging parameters, directing at least two photons into a region of interest, scanning the region of interest across a portion of the tissue, imaging layers of the tissue, sectioning a portion of the tissue, capturing the sectioned tissue, and imaging additional layers of the tissue in a second volume of the tissue, and capturing each portion of sectioned tissue, and processing three-dimensional data that is collected to create a three-dimensional image of the region of interest. Further, captured tissue sections can be processed, re-imaged, and indexed to their original location in the three dimensional image.

  • Publication number: 20070057211
    Abstract: In the systems and methods of the present invention a multifocal multiphoton imaging system has a signal to noise ratio (SNR) that is reduced by over an order of magnitude at imaging depth equal to twice the mean free path scattering length of the specimen. An MMM system based on an area detector such as a multianode photomultiplier tube (MAPMT) that is optimized for high-speed tissue imaging. The specimen is raster-scanned with an array of excitation light beams. The emission photons from the array of excitation foci are collected simultaneously by a MAPMT and the signals from each anode are detected using high sensitivity, low noise single photon counting circuits. An image is formed by the temporal encoding of the integrated signal with a raster scanning pattern. A deconvolution procedure taking account of the spatial distribution and the raster temporal encoding of collected photons can be used to improve decay coefficient.
