X-ray also used? non-intrusive Raman laser beam or soon to be replaced by the

According to the United Kingdom Broadcasting Corporation (BBC) recently reported that United States researchers said the painless Raman laser beam may soon replace the X rays, as a non-intrusive diagnosis of the disease.

This is called Raman Spectroscopy method to help doctors early detection of breast cancer, tooth decay and signs of osteoporosis, diseases become faster, cheaper, more precise.

Raman spectroscopy is mainly used for measuring the molecular density of scattered light and wavelength.

It has been widely used in medical and pharmaceutical fields, for example, researchers using Raman laser measurement inflammatory nature.

United States Michigan University chemist Michael · Maurice in the past few years have been using Raman spectroscopic study of the human skeleton.

He said the Raman laser can replace many surgical and diagnostic. Raman spectra of a great advantage is its non-invasive diagnosis of speed, than the traditional operation faster but also more accurate. He also explained that, when someone is ill or is about to fall ill, their body tissues of chemical substances and healthy body tissues are very different and Raman spectra of different physical changes in the organization.

Morris said that this diagnostic methods that can be completed within a few seconds, it may no longer require the X rays.

The patient simply wrist on the table, put on a silicon steel bracelet-like objects, the objects with Raman laser. Subsequently, the researchers make fiber Raman laser transmission, a few minutes to collect enough signal, then the laser off a few seconds you can know the results.

Morris points out that, in addition to the Orthopedic diseases, Raman spectrum can also be used to detect early signs of tooth decay.

In addition, Raman Spectroscopy diagnosis of many diseases, the patient does not need for blood. For example, in order to detect cholesterol content, a person need only to the laser.

Raman laser can also be used as a non-intrusive way, instead of the typical breast x-ray photography check operation — this method uses low-dose x-ray scans to patients to identify signs of breast cancer.

This laser can "see through" body tissues and produce different spectrum — the variety of color combinations, mainly reflecting the different body tissues. Doctors can body tissue protein structure change of nature, as well as protein, fat and nucleic acid relative number of changes to determine whether the tumor is benign or malignant.

United Kingdom Rutherford Appleton Laboratory · researchers have been using Raman laser analysis of breast tissue calcification, calcification may be early signs of cancer.

United Kingdom Edinburgh Royal Hospital of Biophotonics research department head Nicholas · stone that researchers can look to these phenomena, to determine the calcification of the tumor is malignant or benign.

If this is a malignant tumor, patients need to make a biopsy, if the tumour is benign, a patient may be exempt from inspection. Only in the United Kingdom, this way you can have 8 million patients from surgical biopsy.
