Abstract
A system for analyzing tissue includes a platform and an optical sensing unit coupled to the platform. The optical sensing unit has a detector and a plurality of light sources surrounding and electrically isolated from the detector. The optical sensing units obtain optical data for tissue analysis.
Claims21
A system for analyzing tissue, said system comprising:
- a platform defining a longitudinal axis and having a length along said longitudinal axis;
- and
- an optical sensing unit coupled to said platform with said optical sensing unit having a detector and a plurality of light sources electrically isolated from said detector with said optical sensing unit defining an optical axis parallel to said longitudinal axis, wherein said plurality of light sources includes at least one first light source and at least one second light source, and said detector being disposed between said first and second light sources along said optical axis, said optical sensing unit obtaining optical data for tissue analysis,
- wherein said platform is a microprobe and said system further comprises a tissue aspiration needle with said microprobe being carried by said tissue aspiration needle.
A system for analyzing tissue, said system comprising:
- a tissue aspiration needle defining a cavity having an opening;
- and
- a microprobe disposed within said cavity and carried by said tissue aspiration needle with said microprobe defining a longitudinal axis and having a length along said longitudinal axis,
- said microprobe having a platform and a plurality of optical sensing units coupled to said platform with said optical sensing units defining an optical axis parallel to said longitudinal axis and linearly arranged along said length and along said optical axis, said optical sensing units being exposed through said opening of said cavity, with each of said sensing units having first and second light sources and a detector arranged between and electrically isolated from said first and second light sources along said optical axis;
- wherein said plurality of sensing units obtain optical data substantially simultaneously for analyzing the tissue.
A method of analyzing tissue utilizing a system comprising a platform defining a longitudinal axis and having a length along said longitudinal axis and an optical sensing unit coupled to the platform with the optical sensing unit defining an optical axis parallel to the longitudinal axis and with the optical sensing unit having a detector and a plurality of light sources electrically isolated from the detector, wherein the plurality of light sources includes at least one first light source and at least one second light source with the detector being disposed between the first and second light sources along the optical axis, wherein said platform is a microprobe and said system further comprises a tissue aspiration needle with said microprobe being carried by said tissue aspiration needle, said method comprising the steps of:
- directing a light from the first and second light sources toward the tissue;
- obtaining optical data while the light is being directed toward the tissue;
- utilizing the optical data to analyze the tissue.
