The proposed research is to design, develop and validate an artificial ear-canal that simulates the electrical noise conditions that exist when taking EVestG measurements by associated bio-signal amplifiers. Such a simulator will allow the rapid, rational and accurate refinement of such amplifiers and tympanic electrode; it will also allow improvements to be made to the […]

This proposed research aims at developing a fully automated computerized system for multiple spinal disease diagnosis. It improves the efficiency of the current clinically workflow. The development of the research is based on the state-of-the-art computer vision and image processing techniques. To the best of our knowledge, our group is the first group focusing on […]

Microwave imaging has gained interest in biomedical imaging because of its non-ionizing and non destructive approach. It will be quick, comfortable and cheap compared to current imaging modalities available such as X-ray tomography and magnetic resonance imaging (MRI). In microwave imaging, the major challenge is the design of microwave sensors for receiving scattered signal from […]

Recently, a new whole-body PET/MRI scanner was developed and installed at St. Joseph’s Healthcare in London, Ontario and remains the only installation in Canada. Two major challenges concerning PET imaging include the need for correcting for loss of photons, called attenuation, due to interactions with patient tissues and the impact of respiratory induced organ/tumour motion […]

31 pairs of spinal nerves, containing both sensory and motor nerve fibers, serves two important functions: pathway for sensory, motor impulses and are essential for spinal reflexes. Damage of spinal nerves has been one of the major concerns in diagnosis, treatment and spinal intervention. This project proposes to promptly and accurately extract neurological structures from […]

Research has shown that by monitoring the vibration of the heart using a simple sensor mounting on the human chest, the mechanical characteristics of heart can be measured. The purpose of this research is to design software that can automatically find some important points on the SCG signal. The software will be used to find […]

Snoring during sleep is common and is sometimes indicative of a mechanical impediment to breathing. The condition, called high upper airway resistance, is thought to be relatively common affecting roughly 15% of the population. It is characterized by complaints of daytime fatigue and/or sleepiness and is associated with a myriad of disastrous effects on a […]

This project will develop a low cost, high-frequency ultrasonic scanner that will provide two dimensional images of small animals. The system is targeted at the academic researchers and small biotechnology firms that use small animals for basic science research or testing of therapeutics. A novel scanning mechanism, currently at prototype stage will be developed and […]

The first successful clinical application of nanotechnology was the use of a nanoparticle container to deliver a drug to a tumour. That basic strategy of using a nanoparticle to carry a treatment or indicator molecule has a lot of potential, but requires continued research to determine the therapeutic effectiveness and potential toxicity of each container […]

Since the mid 1970s, medical personnel have used the Glasgow Coma Scale (GCS) as an important tool to rate and describe levels of consciousness. This scale is rudimentary and subjective, often resulting in misdiagnoses in cases where people lack the capacity to communicate. In some unfortunate situations, severe neurological damage can render people unable to […]

Conventional ultrasonography is limited in its ability to image small structures within the ovaries (eg. the eggs and surrounding cells, small fluid filled sacs that contain the eggs known as 'early antral follicles', the structure of the ovulation glands). Preliminary data obtained from our research team at the Canadian Light Source (CLS) have indicated that […]

Reports of in vivo total hip replacement failures have raised concerns over their load bearing capacity, safety, reliability and service life particularly as hip arthroplasty is being extended to even younger patients. Therefore, it is crucial to ensure continual patient monitoring and develop proper testing standards. This study focuses on investigating retrievals and in vitro […]
