Imagine that the technical development can take the ultrasound measurement
systems from the large piece of machinery today, to a coin size system
tomorrow.
The factor that has reduced the size of electronic systems over time is
integration and integrated circuits. In this thesis circuit simulator models
of complete ultrasound systems are used to design custom integrated
circuits. These circuits are optimized for low power consumption and small
size. The models that are used predict the acoustic behavior of an
ultrasound system in a simulated measurement situation.
This allows the design of integrated electronics to be customized to a
specific measurement application, where performance can be validated, in one
tool only.
The work in this thesis is excitation and reception electronics for general
ultrasound measurement equipment, as well as specific electronics aimed for
the ultrasound energy measurement situation. These electronic circuits show
that size and power consumption of ultrasound measurement systems can be
reduced significantly with the use of integration.
