goals

After successful completion of the module, students will have basic knowledge of acoustic field theory in fluid media, solids and piezoelectric materials. They can apply this knowledge to concrete physical problems and solve wave propagation problems. They are able to analyze the given problems and to make a decision for the best solution (e.g. analytical calculation compared to simulations). The students know the design of medical ultrasound imaging systems and understand the applied digital signal acquisition and processing methods based on acoustic field theory. They are able to implement important signal processing algorithms themselves, apply them to measurement data and explain their solution approach. The students know the most important international sources of technical literature and are able to use them. Through the exercises in small groups, partly using computers, the students are able to apply their knowledge in practice in a small team. They are able to explain their approach and to discuss it.

content

Ultrasound techniques for diagnostic imaging and therapy an important field in medical engineering. In this course the physics of ultrasound fields is treated first. Based on this, technical systems like ultrasonic transducers and beamformers as well as the reconstruction techniques and the relevant applications in diagnosis and therapy are presented. Several topics treated can be applied in industrial ultrasound as well, e.g. in non-destructive testing.

Main topics of the course are:

  • Acoustic wave propagation in fluids and solids
  • Acoustical properties of tissues
  • The piezoelectric effect
  • Ultrasound transducers and their equivalent circuits
  • Ultrasonic imaging (array beamforming, reconstruction)
  • Doppler-flow
  • Ultrasound contrast media
  • Special topics (elastography, photoacoustic, harmonic imaging, HIFU-therapy, superresolution-imaging)
