Photoacoustic Imaging

Photoacoustic imaging (PAI) is an emerging imaging technique that combines the strength of light and ultrasound. When a short pulsed light illuminates the target, the light is absorbed and generates sound (photoacoustic) waves. Because it uses light, PAI can provide information about the color or absorption properties of the sample, looking deeper inside the body with clearer resolution.

In our lab, we are actively developing multiscale PAI systems that range from microscopic resolution to macroscopic imaging for clinical applications. We also explore multispectral analysis of biological tissues for visualizing blood vessel network, monitoring oxygenation, detecting tumors, and assessing tissue function. Furthermore, our team explores the translation of PAI into clinical settings, aiming to develop compact and transportable devices.

Advanced Ultrasound Imaging

Ultrasound imaging (USI) has been widely applied to visualize internal structures, particularly in clinical medicine. The basic principle of USI is based on the pulse–echo detection of acoustic waves. To go beyond the conventional limits, advanced methods integrating high-resolution hardware, intelligent algorithms, and novel scanning modes have been actively studied.

In our lab, we focus on developing advanced USI technologies across both biomedical and industrial applications. Our research includes ultrafast Doppler ultrasound for monitoring blood flow and microcirculation dynamics, AI-based image enhancement for reducing artifacts and improving structural clarity, and non-destructive testing using scanning acoustic microscopy (SAM) for high-resolution characterization of materials.

By bridging healthcare and industry, our goal is to create next-generation USI platforms that expand the scope and impact of acoustic technologies.
