High tech equipment has taken the place of the magic sponge in Harvard's training room. The Dillon Field House facility is one of a handful in the country with its own X-ray machine and technician, Baker says. In addition, trainers can prescribe ultrasound and electrostimulating treatment or rehab work on a new $35,000 CYBEX isokinetic machine, which regulates resistance as athletes flex injured joints...
...order to save the others. So far, fewer than 100 women have undergone the procedure, called fetal reduction, at a handful of U.S. hospitals. Usually performed before the twelfth week of pregnancy, it requires that the doctor pierce the mother's abdomen with a needle and, guided by an ultrasound image, inject a lethal drug into the fetus. It dies within minutes. The remaining infants, usually two, then have a much improved chance of developing normally...
...diagnose the condition, some dentists are now relying on sophisticated equipment, which includes ultrasound to measure the "noise" of the joint, as well as devices that record muscle electrical activity and track jaw motion. Other practitioners believe much of the high-tech, high-cost gadgetry is unnecessary. No matter how the diagnosis is made, experts usually favor a conservative treatment regimen that includes a switch to a softer diet (no steak or chewy candy, for example); application of warm, moist heat; facial massages; and exercises to stretch tight muscles. Aspirin, muscle relaxants, tranquilizers and antidepressants may be prescribed. Counseling...
Preventive veterinary medicine is burgeoning. Animal doctors now routinely use X rays and other imaging techniques to detect nearly invisible hairline cracks in horses' legs before fractures occur. For tendon and ligament injuries, says University of Pennsylvania Veterinarian Virginia Reef, "diagnostic ultrasound has been a big boon in racing and horse-show circles." Racing has become such big business that young horses increasingly compete regularly when they are only two years old, before their bodies are fully mature. Equine Specialist Howard Seeherman of Tufts uses the treadmill % to condition yearlings in order to reduce injuries and improve performance. Says...
Other scientists are seeking a better understanding of why the ceramics become superconductors. Many labs have taken pictures of the materials with electron microscopes, pulsed beams of neutrons, X rays and ultrasound. A team of Bell Labs and Arizona State scientists has produced electron-microscope photographs that show defects in the compound's crystalline structure. Says Team Leader Abbas Ourmazd: "We don't quite understand what role the defects play, but it raises some provocative questions. Is it the perfect material that is superconducting? Or is it the defects? If it turns out that it is the defects, then...
