We present the framework for wearable joint rehabilitation assessment following acute knee injury based on the measurement of acoustical emissions from the knee with miniature microphones.‎ The knee is one of the most frequently injured parts of the body.‎ Additionally, knee injuries are among the most severe in terms of time of restricted and ‎/ or total loss of participation among athletes, military personnel, and other populations engaged in high performance activities.‎ This work can enable, for the first time, wearable sensing of knee joint acoustical emissions for longitudinal monitoring of in-depth knee joint health parameters for patients rehabilitating an acute knee injury.‎ Read More

Methods for 2D and 3D Endobronchial Ultrasound Image Segmentation

Endobronchial ultrasound (EBUS) is now commonly used for cancer-staging bronchoscopy.‎  Unfortunately, EBUS is challenging to use, and interpreting EBUS video sequences is difficult.‎ To assist with these issues, we propose computer-based methods for segmenting 2D EBUS frames and 3D EBUS sequences.‎  Both the 2D and 3D segmtentation methods compare very favorably to ground-truth results for a human lung-cancer patient EBUS database.‎   We also demonstrate the potential of the methods for EBUS localization in a multimodal image-guided bronchoscopy system. Read More

QRS detection algorithms are needed to analyze electrocardiogram (ECG) recordings.‎ We describe a QRS detection algorithm that is suitable for clean clinical ECGs as well as poorer quality telehealth ECG.‎ We evaluate the performance of the algorithm on both clinical and telehealth ECGs.‎ The results demonstrate that the proposed algorithm is superior to published algorithms which have inadequate performance on poorer quality telehealth ECGs.‎ The proposed algorithm could be used to manage increasing telehealth ECG analysis workloads.‎ A data repository of annotated telehealth ECGs has been made available on-line for future algorithmic development and testing.‎  Read More

Towards a Portable Cancer Diagnostic Tool Using a  Disposable MEMS-based Biochip

A portable cancer diagnostic tool integrated with a disposable MEMS-based biochip is developed for measuring electro-thermo-mechanical (ETM) properties of the breast tissue.‎ The ETM properties of the normal and cancerous breast tissues are measured by indenting the tissue placed on the biochip integrated inside the 3D printed tool.‎ To overcome the challenges posed by soldering or wire bonding in the microscale devices, we use press-fit contacts for taking out electrical contacts from the biochip, establishing a novel way of connecting
biochip to the electronic module.‎ Our preliminary study shows that the cancer diagnostic tool can successfully delineate normal and cancerous tissues based on the ETM properties.‎  Read More
