Research Overview:

Our lab focuses on embedded system and ultrasound technologies with applications in medical instrumentation. Embedded system is a highly specialized computing system performing device specific task. It contains microcontrollers or Field Programmable Gate Array (FPGA) as the computing core. Our lab specialize in LabVIEW, a cross platform graphic programming language from National Instruments and is equipped with the latest hardware from National Instruments including multi-function data acquisition hardware, compactRIO system, PXI system with modular instruments and multi-functional FPGA, and LabVIEW robotics kit for fast prototype development. Our projects include:

  • Wireless healthcare: wireless healthcare provides help in chronic care management, real time diagnostic monitoring, medication management and senior independent living. This research focuses on the establishment of a wireless sensor network platform based on IEEE 801.15.4 standard that can monitor the patient vital signals (ECG, temperature, blood pressure) in real time. The system includes low cost, light-weighted mobile units capable of collect biosignals and backend data processing station. It can provide a complete history as well as real time monitoring of the patient medical conditions and help doctor in diagnosis of diseases and detection of early warning signs of major medical events such as stroke and heart attack. The system is scalable and can be used either in home or hospital settings.
  • Vision Prosthesis: Our research focuses on the evaluation of the performance of implanted vision prosthesis and related assistive technology. We have built vision prosthesis simulator platform to avoid the risk of using volunteers with true vision implant. Current projects include information delivery through phosphene image and potable navigation assistant device for the vision impaired patients.
  • Ultrasound Assessment of Skeleton System: Current research focuses on the modulated ultrasound in both diagnostic and therapeutic applications in muscular skeletal system. Our study has demonstrated that frequency modulated ultrasound is a promising ultrasound signal format in the assessment of bone properties. Amplitude modulated ultrasound also demonstrated that it can deliver mechanical stimualtion to enhance bone healing. Further research will seek the optimal modulated ultrasound signals for diagnostics and treatment of muscular skeleton diseases.
  • High Performance Computing: High performance computing (HPC) usually relies on supercomputers to solve complex problems. Recent technology has enabled us to build HPC system with low cost off shelf components. Current research focuses on the use of LabVIEW FPGA to accelerate biological computation problems.
