Correction: Confocal Raman microspectroscopy for skin characterization: a comparative study between human skin and pig skin

High Performance Method for Skin Roughness Detection Using Raman Spectroscopy

Combined in vivo confocal Raman spectroscopy and confocal microscopy of human skin.

In vivo confocal Raman spectroscopy is a noninvasive optical method to obtain detailed information about the molecular composition of the skin with high spatial resolution. In vivo confocal scanning laser microscopy is an imaging modality that provides optical sections of the skin without physically dissecting the tissue. A combination of both techniques in a single instrument is described. Thi...

The need for skin pen marking for sentinel lymph node biopsy: A comparative study

  Introduction: There is a consensus in the literature that sentinel lymph node biopsy is the standard procedure for axillary staging in early stage (I and II) breast cancer patients. Usually during lymphoscintigraphy, the location of the sentinel lymph node is marked on the skin by an indelible ink. In this study we evaluated this issue in our patients. Methods: 40 ...

Correction of diffraction effects in confocal Raman microspectroscopy.

A mathematical approach developed to correct depth profiles of wet-chemically modified polymer films obtained by confocal Raman microscopy is presented which takes into account scattered contributions originated from a diffraction-limited laser focal volume. It is demonstrated that the problem can be described using a linear Fredholm integral equation of the first kind which correlates apparent...
