Area of Science:

  • Medical imaging analysis
  • Computational pathology

Background:

  • Multimodal imaging increases data but complicates diagnostic information extraction.
  • Multispectral analysis (MSA) offers a solution by combining unlimited images and automatically extracting tissue properties.

Purpose of the Study:

  • To develop and evaluate a software solution for multispectral analysis (MSA).
  • To enable automated segmentation and analysis of multimodal medical images.

Main Methods:

  • Developed MSA software with unsupervised (EM-algorithm, k-means) and supervised (Bayesian, kNN) classification algorithms.
  • Included a user-friendly interface for class description management and results visualization.

Main Results:

  • Tested software on various image sets, including multimodal brain MRI (T1/T2-weighted, perfusion, diffusion maps).
