Despite significant progress in its treatment, atherosclerotic
cardiovascular disease causes more than 19 million deaths annually,
which is more alarming than other illnesses such as cancer. The
main research focus in this area is on effective prevention, diagnosis,
and treatments. Intravascular ultrasound (IVUS) imaging, which
features real-time display of blood vessel structures, has become an
important diagnostic imaging technique and is considered the new
“gold standard”. However, IVUS has limited image resolution and
is monopolized by a few companies. Therefore our team has used
novel piezoelectric materials (PMN-PT) to develop a miniaturized
IVUS transducer of special design and corresponding manufacturing
techniques. This technology can be used to develop new IVUS
devices of higher spatial resolution and sensitivity that can produce
high quality images.
