RF data for the scientific research in MATLAB environment
Majority of the commercial ultrasound machines are closed for the researchers and do not provide access to raw RF signals. These signals carry valuable information about acoustic wave and tissue interactions and it could be employed fo the developments of new diagnostic methods. TELEMED offers research tools for scientific engineers working in biomedical ultrasound field which allows to analyze RF data acquired by the new generation TELEMED ultrasound scanner ArtUs which is currently in the pre-release stage.

The research package is implemented in the MATLAB® (MathWorks, Inc., Natick, Massachusetts) environment and contains graphical user interface (Fig. 1) which allows to import and review annotated RF data and collection of scripts illustrating conventional RF signal processing steps, which are typically used in the B mode image formation engine.

The tools open new possibilities for:

Engineering viewpoint

Clinical practice viewpoint

  • Develoments of novel ultrasonic quantitative tissue characterization methods
  • Derivation of novel biomarkers for: recognition, charactrization and differentiation of various lesions and asessment of treatment (i.e. thermal ablation effciency, sonoporation)
  • Investigation of acoustic properties of tissue and tissue mimicking materials
  • In-vitro studies of tissue (i.e. investigation of biopsy samples)
  • Developments of novel parametric imaging techniques
  • New sources of contrast for imaging of various lesions (tumors, tissue fibrosis, atherosclerotic plaques and much more)
  • Creation of advanced digital image processing algorithms for speckle reduction, and image enhancement
  • Better quality of ultrasound diagnostic images more appropriate for visual expert’s evaluation
