Abstract:

Systems for protein quantitation using a Fabry-Perot interferometer. In one arrangement, a quantitation device includes an infrared source, a sample holder, and a Fabry-Perot interferometer positioned to receive infrared radiation from the source passing through a sample on the sample holder. A band pass optical filter sets the working range of the interferometer, and radiation exiting the interferometer falls on a detector that produces a signal indicating the intensity of the received radiation. A controller causes the interferometer to be tuned to a number of different resonance wavelengths and receives the intensity signals, for determination of an absorbance spectrum.

Abstract:

Described herein are methods, systems and devices for image-guided, computer-assisted surgical procedures, in particular for intra-operative registration of anatomical structures. Embodiments of the invention may enable a user to register the surface of an anatomical structure intra-operatively in an interactive, computer-guided process. The user may send information about acquired data points to the computer, and the computer may evaluate the aggregate of data points, optionally provide instructions to the user for acquisition of additional data points, and signal to the user when sufficient data points have been acquired for registration of the surface of the anatomical structure.
