Research
Our research advances ultrasound from a conventional imaging modality into an intelligent platform for quantitative diagnosis, targeted therapy, and integrated engineering applications.
Research area 01
AI-based Ultrasound Imaging
Artificial intelligence, signal processing, and quantitative analysis for clearer views of blood flow, vascular motion, and tissue properties.
Need
Conventional ultrasound can make complex flow and vessel-wall behavior difficult to quantify, particularly near moving boundaries.
Approach
We combine ultrasound signals with deep learning, speckle tracking, super-resolution methods, and physics-aware analysis to extract interpretable measurements.
Methods and themes
- Ultrasound blood-flow and hemodynamic analysis
- Super-resolution imaging and speckle tracking
- Vascular wall segmentation and motion analysis
- Quantitative analysis from ultrasound signals
Impact
The work supports more detailed analysis of vascular flow and flow–vessel interaction while connecting imaging algorithms to measurable biomedical questions.
Research area 02
Therapeutic Ultrasound
Focused ultrasound, cavitation, histotripsy, and ultrasound-assisted delivery for precise and monitorable treatment approaches.
Need
Non-invasive therapy must localize mechanical or delivery effects while preserving surrounding tissue and providing evidence of treatment progress.
Approach
Published studies combine acoustic trapping, boiling histotripsy, acoustic lenses, and ultrasound-responsive carriers with imaging and monitoring strategies.
Methods and themes
- Sonothrombolysis and acoustic trapping
- Histotripsy and focused ultrasound
- Cavitation monitoring
- Ultrasound-assisted drug delivery
Impact
These systems examine how ultrasound can mechanically target clots or support localized delivery while making treatment behavior observable.
Research area 03
Ultrasound Systems & Multiphysics Applications
Integrated ultrasound systems informed by acoustics, fluid mechanics, heat transfer, signal processing, and computational modeling.
Need
Biomedical ultrasound systems operate across interacting physical domains, so isolated models may miss the behavior that determines measurement or treatment performance.
Approach
We connect acoustic fields, biofluid motion, thermal transport, beamforming, and computational models to reason about system-level behavior.
Methods and themes
- Acoustics and acoustic radiation force
- Fluid mechanics and hemodynamics
- Signal processing and beamforming
- Computational and multiphysics modeling
Impact
A multiphysics view provides a foundation for designing and interpreting ultrasound systems across biomedical and broader engineering applications.
Robotics
Robotics is managed within Ultrasound Systems & Multiphysics Applications as part of the lab’s integrated engineering content.
