FDTD of (ultrasound) wave propagation through muscle

Click For Summary
SUMMARY

The discussion focuses on simulating ultrasound wave propagation through muscle tissue using the Finite-Difference Time-Domain (FDTD) method in MATLAB. The user is a mechanical engineering student seeking guidance on calculating node displacements based on the wave equation in two dimensions. Key challenges include understanding the implementation of the FDTD algorithm and the need for appropriate references to support the simulation process. The lack of direct experience among forum members highlights the niche nature of this topic.

PREREQUISITES
  • Understanding of the Finite-Difference Time-Domain (FDTD) method
  • Proficiency in MATLAB programming
  • Familiarity with wave equations in two dimensions
  • Knowledge of ultrasound wave propagation principles
NEXT STEPS
  • Research the implementation of the FDTD algorithm in MATLAB
  • Study the mathematical foundations of wave equations
  • Explore existing literature on ultrasound propagation simulations
  • Investigate numerical methods for calculating node displacements
USEFUL FOR

This discussion is beneficial for mechanical engineering students, researchers in biomedical engineering, and professionals interested in ultrasound simulation and wave propagation modeling.

Im a mechanical engineering student currently, with a third year project of simulating ultrasound propagation through the abdomen. Currently i just want to simulate it going through muscle with no obstacles. I don't really understand where to start, I have formed some equations based on the wave equation in 2-d and understand vaguely that I have to some how calculate the displacement of all nodes for the previous two time steps to calculate the future, but I'm not really sure how one would do that. If anyone has any experience in this and could give me some insight or guidance that would be greatly appreciated. I am working with MATLAB for the coding.

What references are you using for your work? Apparently there are no forum members with experience in such a simulation, but if people could see the references, they might be able to answer questions about the material.
