Are multiples of the transducer frequency |
|
|
|
Harmonics are created in |
Tissues not the transducer or receiver |
|
|
|
What creates harmonics |
Non-linear behavior |
Sound moves slightly faster in regions of compression or high pressure and slightly lower in regions of rarefaction or lower pressure |
|
|
Pulse inversion harmonic imaging |
A form of harmonic imaging where positive and negative pulses are transmitted down each scan line. Uses wide bandwidth or broadband transducers. |
|
|
|
Major disadvantages of pulse inversion imaging |
Frame rate is half that of fundamental imaging. Degrades temporal resolution while improving spatial resolution. |
