Аннотация

Intravascular photoacoustic (IVPA) imaging, which combines the advantages of high ultrasonic resolution and strong optical absorption contrast, seems to be an alternative method to detect lipid pool and atherosclerotic lesion. A highly sensitive miniaturized ultrasound transducer is required for receiving of intravascular photoacoustic signals. As the core part of the transducer, lead-based piezoelectric materials have been most popular for IVPA applications because of their excellent piezoelectric behavior. However, in view of environmental protection and human safety issues, the use of lead is a problem due to its toxicity. Therefore, it is of urgent need to develop lead-free piezoelectric materials that can be used as intravascular PA signal receivers. The aim of the present study is to demonstrate the feasibility of KNN-based single crystals to be implemented in IVPA applications for the detection of lipid pool and calcification.
