A new ultrasound imaging simulation framework, FOCUS, offers rapid and accurate modeling of soft tissue propagation and scattering. It enables efficient simulation of various modalities, including color Doppler, for advanced ultrasound technique development.

Area of Science:

  • Medical Imaging
  • Computational Physics

Background:

  • Ultrasound imaging simulations are crucial for developing and validating new techniques.
  • Existing methods face limitations in speed, accuracy, and scalability for complex scenarios.

Purpose of the Study:
