Advances in Computer Assisted Mosaic Arthroplasty

2012/13-2017/18 • $170,000 • PI
Cartilage degeneration is a widespread problem which occurs predominantly in the knee, ankle, and shoulder. For younger, active patients, early cartilage replacement can result in a much improved quality of life and can delay or eliminate the eventual need for prosthetic joint replacement, with...

Research Platform for Medical Education Informatics

2016/17 • $149,992 • PI,CO
The equipment will support research in medical education informatics. We are witnessing revolutionary changes in medical education, where much progress has been driven by harnessing the power of modern informatics. Traditionally, medical trainees practice on real patients under the supervision...

Spatially Navigated iKnife

2015/16 • $148,810 • PI,CO
<p>The equipment requested will support a wide range of translational science and engineering research in the theme of advanced computational surgical navigation.<br /> <br /> Computational surgical navigation systems brought major advances to many areas of surgery during the past decade....

Patient-specific cartilage implants: development and surgical implantation

2012/13-2014/15 • $239,229 • PI,CO
Damage to articular cartilage by arthritis or injury causes significant morbidity as the tissue has little potential for repair. One approach to resurface the damaged area with engineered cartilage. However, as only a limited number of cells can be extracted from a patient, the approach is...

Computational Guidance for Rapid Evaporative Ionization Mass Spectrometry

2014/15 • $149,480 • PI,CO
Rapid evaporative ionization mass spectrometry (REIMS) is a revolutionary technique that allows real-time characterization of human tissue and bacterial species by analysis of aerosol released during electrosurgical dissection or evaporated and ionized. This revolutionary technique still has a...

2012/13-2013/14 • $239,229 • PI,CO
Damage to articular cartilage by arthritis or injury causes significant morbidity as the tissue has little potential for repair. One approach to resurface the damaged area with engineered cartilage. However, as only a limited number of cells can be extracted from a patient, the approach is...

A system for real-time, portable 3D medical imaging acquisition for interdisciplinary research

2013/14 • $126,644 • PI,CO
The requested system combines two unique portable medical imaging acquisition devices: a handheld 3D scanner for real-time scanning using structured light and a portable ultrasound (U/S) machine for real-time scanning using sound waves. Both imaging devices are portable, fast, have 3D capacity,...

New Methods for Articular Cartilage Repair through Computer-Assisted Surgery

2010/11-2011/12 • $161,270 • PI
Articular cartilage injuries, particularly in the knee, can lead to long-term damage and severe loss of joint function. Unlike many tissues, articular cartilage is not vascularized and does not naturally repair when damaged, so surgical intervention is often required. Total joint replacement is...

Visualization and interfaces for computer-assisted surgery

2010/11-2011/12 • $38,000 • PI
Computers are used in surgery to improve patient outcomes and to reduce operating times. My research is about visualization methods and user interfaces for computer-assisted surgery. We are developing methods to visualize potential errors in the surgical guidance system so that the surgeon can...
