Executive Summary

To make colon cancer screening more broadly accessible, Massachusetts General Hospital (MGH) sought to reduce the time required to electronically cleanse and view a Three-Dimensional (3-D) model of the colon from an hour to five minutes. MGH reduced processing times to two minutes by optimizing its native Visual C++ code for 64-bit execution and using the Microsoft Parallel Patterns Library to parallelize the code, achieving the performance required to support mass colon cancer screening. The screening approach pioneered by MGH can also drastically decrease costs and is far more patient friendly, avoiding the many negatives of an optical colonoscopy.
