Abstract
A system for assessing biological tissue is disclosed. The system contains an illumination hardware arrangement comprising transmission and sensing hardware, the illumination hardware arrangement configured to inspect a biological tissue using at least two modes from a group containing: a three dimensional stereo imaging mode; a fluorescence imaging mode; a reflectance imaging mode; and a thermal imaging mode; and processing hardware configured to operate the illumination hardware arrangement according to a protocol comprising inspection settings of the at least two modes, wherein the processing hardware receives scan results for the at least two modes from the illumination hardware arrangement and identifies attributes of the biological tissue by constructing a three dimensional dataset from the scan results for the at least two modes and analyzing the three dimensional dataset.
Core Innovation
The invention relates to a system for assessing biological tissue. The system inspects biological tissue using at least two modes from a group comprising a three dimensional stereo imaging mode, a fluorescence imaging mode, a hyperspectral imaging mode, and a thermal imaging mode. The system includes an illumination hardware arrangement comprising transmission and sensing hardware configured to perform the inspection according to a protocol comprising inspection settings of the at least two modes.
The system further includes one or more 3D stereoscopic imaging cameras in which each stereoscopic imaging camera includes two sensors spaced a known distance apart such that each stereoscopic imaging camera takes two images from the two sensors and compares them to provide morphological information. The system also includes one or more thermal imaging cameras to provide at least one of IR images and thermal images.
The processing hardware receives scan results for the at least two modes from the illumination hardware arrangement. The processing hardware constructs a three dimensional dataset from the scan results for the at least two modes and analyzes the three dimensional dataset to identify attributes of the biological tissue. The identified attributes support tissue assessment by using multimode scan results to derive tissue attributes and by analyzing the constructed three dimensional dataset.
