Study of Repetitive Stress Injury in Ultrasound Technicians
In 2009 90% of sonographers reported scanning in pain. Sonographers suffer from work-related musculoskeletal disorders as a result of ergonomic hazards and working conditions. The purpose of this study is evaluating the upper extremity kinematics and kinetics while a sonographer is scanning the kidneys with their dominant hand. Greater understanding of the loading in the upper extremity due to muscular activity during scanning could be helpful in assessing risk of injury because continuous co-contraction of muscles from long-term static loads without sufficient breaks could result in muscle fatigue and reduced local blood circulation. Frequent co-contraction in the muscle is also a source of injury. Quantifying the loading in the upper extremity would be useful in evaluating the effectiveness of future transducer designs to reduce injury.

Automatic atlas based registration and segmentation of bones from fused CT/nuclear imaging data sets
Longitudinal preclinical imaging studies generate large quantities of data. Analyzing this data is a time consuming process, usually done by hand, sometimes with the aid of software. Relying on human interpretation can lead to different and sometimes conflicting results. My project uses an articulated skeletal atlas of a mouse. This atlas is registered to the ct data, then the registered atlas is applied to the fused nuclear imaging data set to extract uptake for individual bones. The entire process is automated, saving the researcher time and providing consistent results.

Development of computer-aided detection (CAD) tool for liver metastasis micro CT imaging using targeted contrast agent
Preclinical in-vivo micro CT studies of liver metastasis are difficult due to poor inherent soft tissue contrast and the need for highly technical, manual analysis of the data. Research has implicated that Kupffer cells in the liver encapsulate liver metastases providing an opportunity to deliver macrophage-specific contrast agents for the detection of small metastatic lesions. The Kupffer cell targeting contrast agent will enable automated detection of liver lesions via CAD software and allow for large scale studies. This imaging method could be a useful tool to facilitate longitudinal imaging of liver metastases in mice and has the potential for translation into clinical practice.

Electronic Laparoscopy Trainer
Surgical training for laparoscopic surgery, a minimally invasive abdominal surgical technique, is currently performed using either virtual reality systems or more commonly simple box trainers. A need for a more interactive data-driven training protocol has been identified. In collaboration with educators at Grand Rapids Medical Education Partners an electronic device is being developed and tested to add data functionality, interactive features, and data collection to existing box trainers.

Heart Rate Artifact Suppression
Motion artifact strongly corrupts heart rate measurements in current pulse oximetry systems. In many, almost any motion will greatly diminish the system’s ability to extract a reliable heart rate. The artifact is most likely present due to normally non-pulsatile components of the body, such as venous blood and tissue fluid, which become pulsatile during motion. Through the use of hardware, software, and signal processing techniques, a wearable heart rate monitor that is not susceptible to motional artifact will be developed. The final goal will be to design a device that can reliably extract the subject’s heart rate despite the presence of motion artifact.

Modeling carotid arterial stenosis and studying the physical properties, with the intended goal to create a model to more accurately predict plaque rupture. I am using current CFD techniques to create the model.
Creating a Power Wheel Chair Training platform intended to help young people with motor disabilities learn to use a Power Wheel Chair.

I am in the process of making revisions and upgrading a power wheel chair trainer. The current power wheel chair trainer was built 2 semesters ago and was not suitable for some of the students at Lincoln Development Center. The changes include: Making it longer, rounded front bumper for easier doorway access, stronger connection between drive unit and wheelchair platform, longer battery life in the drive unit and the wireless remote. Myself and a few other bio-med grad students will be designing and building an all new power wheel chair trainer in the near future.
