Comparison of Different Middle Ear Prostheses in Conducting Mechanical Vibrations for Hearing Reconstruction

Currently, surgeons often reconstruct the middle ear to restore hearing with artificial prostheses that reconnect the middle ear bones that have been destroyed. This process is unpredictable and these prostheses are available in hundreds of different forms from many companies. The supervisor of this project runs one of the foremost laboratories in the world in exploring the vibration transmission properties of prostheses.

Kinematics Modelling and Trajectory Design for Arm and Shoulder Physical Therapies Performed by Rehabilitation Robots

This project involves studying the kinematics of the human body during physical therapies on the arm and shoulder. With guidance and assistance from Glenrose Hospital, the intern will collect a library of typically prescribed motions of the shoulder and arm during physical therapy. He will then develop a mathematical model to represent the kinematics of the arm and shoulder as well as a parameter identification routine to identify the model parameters using simple moves and coordinate measurement techniques.

Co-registration of Nuclear Medicine Images with Anatomical Images for Attenuation Correction and Localization of Activity

Medical image registration is the task of bringing two images into spatial alignment. Automatic and accurate 3D co-registration of nuclear medicine 3D image data with 3D anatomical data is crucial for improving the functional image reconstruction through anatomy-based attenuation correction. Co-registration is also important for the fusion of anatomical data with functional information. Most registration methods involve optimizing an intensity-based similarity metric that is defined by the transformation parameters.

Ultra Wide Band Antenna Design for Microwave Breast Imaging

Existing screening techniques for detecting breast cancer like X-ray Mammography, Magnetic Resonance Imaging (MRI), and Computer Assisted Tomography (CT) have some drawbacks, such as the inability to detect cancer at early stage, over sensitivity or requirement of breast compression. A new approach that has the potential to overcome these shortcomings is Ultra Wide Band (UWB) microwave imaging. This imaging method is based on solving Maxwell’s equation to determine dielectric properties profile with known electric field measured by antennas surrounding the breast.
