This study analyzes how biomedical ultrasound interacts with spherical tumors. It models both the tumor and surrounding tissue as elastic, lossy materials to predict scattered ultrasound patterns.

Area of Science:

  • Biomedical Engineering
  • Acoustics
  • Medical Physics

Background:

  • Biomedical ultrasound is crucial for diagnostics and therapeutics.
  • Understanding ultrasound interaction with biological tissues, especially tumors, is vital for effective treatment planning.

Purpose of the Study:

  • To investigate the interaction of biomedical ultrasound with spherical human tumors.
  • To predict the angular distribution of scattered ultrasound waves analytically.

Main Methods:

  • Utilized analytic methods to model ultrasound scattering.
  • Considered both tumor and surrounding tissue as lossy elastic media.
  • Incorporated compressional and shear-wave acoustic modes in the analysis.

Main Results:
