An E-Team to Develop an Image Quality Analyzer for Endoscopes and Laparoscopes

University of Pittsburgh, 2001 - $13,000

According to the American Hospital Association, there are 6,400 hospitals in the US, and most of them own endoscopic equipment. Endoscopes and laparoscopes are narrow, tube-shaped optical devices that allow surgeons to see inside a patient's body without making incisions. The devices minimize trauma in surgery and therefore shorten patient recovery time. However, scope performance depends on the image quality they deliver, and many factors contribute to image quality deterioration, including collision with alien objects, poor maintenance, and the heat and chemicals used in cleaning and sterilization procedures. Currently, hospitals have no tool to ensure scope performance by evaluating and monitoring image quality.

To fill this need, this E-Team developed an image quality analyzer that facilitates efficient and automatic evaluation of the image quality of scopes. With the analyzer, hospitals can ensure the quality of endoscopic surgery and track the performance of scopes over time. Performance data shows optimal maintenance procedures and when replacement is necessary.

The E-Team consisted of two graduate students in engineering. They worked with an industrial engineering faculty member and the director of minimal invasive surgery at the Magee-Women's Hospital in Pittsburgh.
