The stethoscope symbolizes medicine like no other examination instrument. A laser might replace it in the future.
At the beginning of the 19th century French surgeon René Laënnec invented, it is still used today to make body noises audible. It’s built up stethoscope always the same: It consists of a chest piece, a tube, ear hooks and ear tips.

Measuring the heartbeat with laser and AI
However, it might disappear from medical examination rooms in the future. At least researchers are working on the Scottish one University of Glasgow at a artificially intelligent solutionto replace the diagnostic instrument.
The scientists have one Laser camera developed that Heartbeat one person read from a distance and so first Signs of cardiovascular disease can recognize. The system that Artificial intelligence and state-of-the-art quantum technological measurement techniques uses might “change the way we monitor our health,” it says.
“The technology might be used in booths in shopping centers where people get a quick heartbeat reading, which is then added to their online medical records,” it said Daniele Faccio from the Advanced Research Center at the University of Glasgow Guardian quoted regarding it. The proposed laser heart monitors might also be installed at home and used there to monitor health. Devices programmed differently might monitor blood pressure abnormalities or subtle changes in gait – an early sign of diseases such as Alzheimer’s.
Detect early signs of stroke or cardiac arrest
According to Faccio, monitoring the heartbeat from a distance is ideal for detecting irregularities in cardiac activity – such as heart murmurs or heartbeats that are too fast or too slow – at an early stage stroke or cardiac arrest to announce can.
The system developed by Faccio and his team consists of: High speed cameras, which can capture images at a speed of 2,000 frames per second. A laser beam will be on the High of a person’s neck. The reflections are then used to measure how much the skin rises and falls as the main artery expands and contracts as blood is forced through it. These changes represent movements of just a few nanometers.

However, detecting these tiny fluctuations alone is not enough to track the human heartbeat. Other, much larger movements on a person’s chest – such as breathing – override the heartbeat signals.
“This is where AI comes into play,” explains Faccio. “We use advanced Computer systems, to filter out everything but the vibrations caused by a person’s heartbeat – even if it’s a much weaker signal than the other sounds coming from the chest. We know the frequency range of the human heartbeat, and the AI focuses on this range.”
Die Analysis of the recorded signals enables healthcare staff to detect changes in a person’s heart rate – in comparison to their individual heart behavior.
“This system is very precise,” explains Faccio, who hopes to have it completed next year. “Even if you live in a house with 10 people, it can distinguish your own from the others.”
