Advances in ultrasound — the same imaging technology that uses sound waves to allow doctors to monitor babies in utero — are being applied by engineers at the University of California San Diego to make railroad track inspection more effective. Ensuring the safety of the vast 140,000-mile network of existing rail infrastructure in the United States is critical, especially as that figure grows with the addition of new high-speed passenger rail lines.
