Area of Science:

  • Biomedical Imaging
  • Terahertz Spectroscopy
  • Image Analysis

Background:

  • Effective visualization and classification are crucial for extracting meaningful information from raw imaging data.
  • Terahertz pulsed imaging (TPI) offers unique capabilities for non-ionizing biomedical imaging.
  • Developing robust methods for TPI data analysis is essential for its clinical translation.

Purpose of the Study:

  • To explore and demonstrate visualization and classification techniques in terahertz pulsed imaging (TPI).
  • To apply these techniques for analyzing archived biomedical samples.
  • To achieve successful tissue classification using TPI.

Main Methods:

  • Investigated time- and frequency-domain TPI methods.
  • Utilized both bright-field and dark-field TPI configurations.
