According to US scientists, pain-free Raman lasers may soon replace X-rays and become a diagnostic method of disease without invading the patient's body.

This is called Raman spectroscopy, which can help doctors detect early signs of breast cancer, tooth decay and osteoporosis, thereby helping to diagnose diseases quickly, conveniently and accurately. .
Raman spectra are primarily used to measure the density and wavelength of light emitted by molecules. Raman spectroscopy has been widely used in the field of medicine and drug preparation such as measuring the nature of inflammatory diseases.
Scientist Michael Morris of the University of Michigan, USA, said Raman lasers could replace many surgical and diagnostic methods. The biggest advantage of the Raman spectrum is that it does not need to penetrate the patient's body, the diagnostic speed is faster and more accurate than the traditional surgical method.
When someone is born sick or about to give birth, the chemicals in the organs of the body are vastly different from the chemicals in healthy organs, so the Raman spectrum can be transmitted. birth changes in organizations in different bodies.
Scientists from the Rutherford Appleton Laboratory in the UK regularly use Raman lasers to analyze calcification in breast tissue, because calcification is a primary sign of cancer.
The Raman spectroscopy method can perform diagnosis within a few minutes and the patient may not need X-rays.
