This study introduces an automated method using time-resolved fluorescence imaging to analyze tissue composition. The technique enhances differentiation of tissue types for applications in automated histopathology and faster intraoperative decisions.

Area of Science:

  • Biomedical Optics
  • Molecular Imaging
  • Computational Pathology

Background:

  • Multidimensional fluorescence imaging generates large datasets, complicating tissue type differentiation.
  • Optimizing parameters for contrast enhancement in biological tissues is challenging.
  • Current methods often require explicit modeling of fluorescence decay, limiting automation.

Purpose of the Study:

  • To present a novel, automated framework for characterizing tissue composition using time-resolved fluorescence imaging.
  • To enable consistent differentiation of intrinsic tissue constituents without explicit decay modeling.
  • To facilitate automated histopathology and improve intraoperative decision-making.

Main Methods:

  • Utilized time-resolved fluorescence imaging data.
