Transducer apparatus for intravascular blood flow measurement
摘要:
A dual spiral transducer and method of manufacture of same is disclosed. In one aspect, the transducer comprises a central rod, a first spiral piezoelectric electrode wrapped around a circumference of the rod, the electrode being advanced around the rod at a determined angle determined based on a length of a single complete turn around the rod and a diameter of the rod and a second spiral piezoelectric electrode wrapped around the circumference of the rod, the second spiral electrode being electrically isolated, and offset, from the first spiral electrode by a known distance. A second set of spiral electrodes can be integrated into the structure so that both transmission and reception of signals is feasible.
