Multiple Wavelength Excitation 5-ALA Induced PpIX Fluorescence Spectroscopy in Guided Neurosurgery for Improving Glioma Classification

Not Accessible

Your library or personal account may give you access

Abstract

We present a methodology for PpIX parameters estimation based on multi-wavelength excitation. This method aims to distinguish healthy tissues from tumour mar-gins. It reduces the absolute estimation error of low density margins by 39.9%.
