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 hemodynamic parameters of the heart that will be used for diagnosis of ischemic heart patients. The outcome of this project is anticipated be extremely beneficial for both academia and the company.

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 patient’s health such as high blood pressure, depression, atrial fibrillation, migraine, bruxism, temporal-mandibular joint disorders, fibromyalgia and chronic fatigue syndrome.

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 during scanning. Corrections for attenuation are currently performed using X-ray CT.

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 the target. For effective signal penetration, the frequency of operation has to be low (below 7 GHz), and at this frequency, the sensor size becomes large.

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 this direction. Once success, it will not only improve the clinician’s accuracy, inter and intraobservability, but also promote the technical advancement in the computer vision and image processing.

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 developed signal extraction software algorithms.

Surgical training is increasingly being done using simulator technology in order to teach basic skills to residents without risking patients’ lives. However, neurosurgery lags behind other surgical specialties in the adoption of simulators. Since there are no commercial simulators in this domain, the National Research Council has embarked on a neurosurgery simulator development program, in collaboration with Canadian neurosurgeons.

In our experiments with semiconductor microstructures, such as those used for the fabrication of light emitting diodes (LED), our team has discovered that popular LED devices could also be used for the detection of micro-organisms that come in contact with the device. As a result of our almost 5 years of research, we have demonstrated the operation of an LED-like photonic biosensor capable of rapid (less than 2 hours) detection of E. coli.

This study will investigate the process of information technology adoption within the Canadian health care system in order to uncover the underlying promoters and barriers to technology implementation. The knowledge gained from this study will assist McKesson and other health IT companies to adjust their technologies and deployment strategies for effective technology implementation. Ultimately, more effective technology implementation will result in more efficient workflows and health are delivery.

Positron Emission Tomography (PET) images need correction for the loss of photons. This loss, or attenuation, is due to interactions with patient tissues. Corrections are currently done with X-ray Computed Tomography (CT), however we are proposing a method whereby Magnetic Resonance Images (MRI) are used. This will be done by creating an attenuation map(?-map). The construction of ?-maps can be divided into two categories, patient specific ?-maps by MRI segmentation, and registration of a predefined atlas to an MRI.
