Abstract
Field II has been a recognized simulation tool for
piezoceramic medical transducer arrays for more than a decade.
The program has its strength in doing fast computations of the
spatial impulse response (SIR) from array elements by dividing
the elements into smaller mathematical elements (ME)s from
which it calculates the SIR responses. The program features
predefined models for classical transducer geometries, but currently
none for the fast advancing CMUTs. This work addresses
the assumptions required for modeling CMUTs with Field II. It
is shown that rectangular array elements, populated with cells,
can be well approximated by neglecting the cells. Further, it
is demonstrated that scaling of the SIR translates into better
computational efficiency.
