Terahertz imaging, which is already familiar from airport security checkpoints, has a number of other promising applications — from explosives detection to collision avoidance in cars. Like sonar or radar, terahertz imaging produces an image by comparing measurements across an array of sensors. Those arrays have to be very dense, since the distance between sensors is proportional to wavelength.

Sophisticated medical imaging is often cited as a leading driver of health care costs. The increasing availability of techniques such as computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET), while aiding large number of patients, has also made the treatment of disease and injury more expensive.

Cardiologists at Washington University School of Medicine in St. Louis have developed a noninvasive imaging technique that may help determine whether children who have had heart transplants are showing early signs of rejection. The technique could reduce the need for these patients to undergo invasive imaging tests every one to two years.
