Course aims and content:
PLEASE NOTE THAT THIS COURSE IS TAUGHT IN EINDHOVEN
The physics of acoustics (waves and wave propagation) are the foundation of this imaging course. Starting point is the wave equation, after which several models for wave propagation in elastic and visco-elastic tissue and fluids will be treated. Solution to these equations will be derived for point sources and extended to arbitrary apertures. The physics of attenuation (= damping) and its consequences will be discussed. Next, the physics behind US pressure field formation, including reflection, diffraction, and scattering, will be discussed and it will be shown how this forms the basis of in vivo imaging. A number of techniques to improve image formation will be discussed, including array technology, focusing, advanced beam forming, 3-D ultrasound and plane wave imaging techniques. The concept of speckle, speckle statistics and its relation to tissue morphology will be discussed, including techniques for speckle reduction and image enhancement.
Next, a clear overview of medical applications of ultrasound will be given, including all pro’s and con’s and image artefacts. The basic principles of Doppler and the corresponding signal analysis are shown for the commonly used modes (continuous wave, pulsed wave, color flow & power Doppler). Next, relative new techniques will be introduced, such as speckle tracking, strain imaging and (shear wave) elastography. The physics of piezoelectric materials are treated shortly, after which the design of US transducers is discussed. Photoacoustics will be introduced, from photoacoustic effect to medical imaging applications.
Finally, in a number of guest lectures, two more advanced topics will be discussed that are based on non-linear wave propagation: harmonic imaging and contrast agents and contrast-enhanced ultrasound imaging.
