Stethoscopes on their way out
The cold sensation of the doctor's stethoscope has been familiar to patients for decades. But the device could soon be replaced by new technology, a leading scientific journal has predicted. It claims that a new generation of hand-held ultrasound devices, modelled on smartphones, are able to diagnose heart, lung and other conditions quicker and with more accuracy than the 200-year-old stethoscope.
The editorial article, in Global Heart, the journal of the World Heart Federation, says: "Many experts have argued that ultrasound has become the stethoscope of the 21st century." Ultrasound works by emitting high-frequency sound waves to monitor the structure of soft tissue and blood flow.
