METHOD AND SYSTEM FOR OPTICALLY INVESTIGATING A TISSUE OF A SUBJECT

摘要

There is described a probe device for optically investigating a tissue of a subject, comprising: a first probe element, a second probe element, and a third probe element each to be positioned at a respective vertex of a triangle for sensing the tissue, the first probe element each comprising a first light source for emitting light having a first wavelength, the second probe element each comprising a second light source for emitting light having a second wavelength and a first photodetector for detecting light having the first wavelength and scattered by the tissue, and the third probe element comprising a second photodetector for detecting light having the first and second wavelengths and scattered by the tissue.

1. A system for optically investigating a tissue of a subject, comprising:
a first probe element, a second probe element, and a third probe element each adapted to be positioned at a respective vertex of a triangle for sensing a given region of a tissue, the first probe element comprising a first light source for emitting light having a first wavelength, the second probe element comprising a second light source for emitting light having a second wavelength and a first photodetector for detecting light having the first wavelength and being scattered by the tissue, and the third probe element comprising a second photodetector for detecting light having the first and second wavelengths and being scattered by the tissue; and a control unit operatively connected to at least the first and second probe elements, the control unit being adapted to operate the second light source for sensing a first tissue region comprised between the second and third probe elements, and operate the first light source for sensing a second and a third tissue region respectively comprised between the first probe element and the second and third probe elements.
