T-ray technology reveals what’s getting under your skin
T-rays is a new procedure for analyzing skin structure through the use of a type of radiation rays. It is basically said to bring forth an improved diagnosis upon which more accurate treatments can be based. It could be specifically helpful for diseases such as skin cancer, psoriasis, and eczema.
Scientists from the Chinese University of Hong Kong and the University of Warwick have studied this method closely. They have demonstrated that if T-rays are fired from various angles they can produce a detailed image of the skin. Especially, when it comes to focusing upon a particular area needing to be examined. The method provides a much clearer skin structure and its condition of hydration than any other current procedure.
Advanced Photonics Research has reported this research by a group of scientists. It can possibly be the newest efficient tool for clinicians and scientists. By characterizing skin properties in patients, managing and treatment of skin conditions will become easier.
T-rays or Terahertz rays come basically between WiFi and infrared rays on the electromagnetic spectrum. T-rays have the power to see through various ordinary materials. These include ceramics, plastic, and clothes. Therefore, T-rays are perfect for conducting inspections that are non-invasive in nature. The rays have low-energy photons that are non-ionizing. As a result, they are safe to work within biological environments including medical screening and security.
T-rays can only be detected when they are passing through the skin’s outer layer before reflecting back. The rays that are traveling deeper are too attenuated for detection. Thus, they are potentially effective as a tool to monitor the outermost layers of skin. For testing this theory, the rays were focused on the skin through a prism. This was done so the rays would align with the targeted focal plane. The light would reflect back slightly differently, depending upon the skin’s properties. Scientists then compared the properties of the rays before and after they entered the focused skin area.
However, there are certain limits when it comes to standard Terahertz reflection spectroscopy. In order to overcome that, scientists used ellipsometry instead. This procedure consists of focusing the rays from different angles on the same skin area. The demonstration was quite successful with the use of ellipsometry. The refractive index of the skin could be calculated accurately. The process measured the rays in two directions which were at right angles to each other.
The ellipsometry test was the first time that Terahertz skin birefringence was measured in vivo. according to the cheap essay writing service fast writers, this information can be extremely valuable in terms of medical progress. The T-rays can most accurately confirm how much hydrated the skin is and also calculate the skin’s thickness.
Professor Emma Pickwell-MacPherson works in the Department of Electronic Engineering in Chinese University and the Department of Physics at Warwick. Professor MacPherson stated that they wanted to demonstrate that human skin measurements were possible by in-vivo ellipsometry. It can efficiently calculate the properties of human skin most accurately. In the reflection imaging gained by ordinary terahertz, the refractive index and thickness is combined as one. By measurements taken from multiple angles, it is possible to separate them.
Professor MacPherson further said that hydrated skin has a different refractive index in comparison to skin that is dehydrated. The people having skin disorders could have their skin hydration levels examined quantitatively. This is not possible to such an accurate extent with the current existing treatments. Even with efforts being made to improve the skincare products for skin conditions such as psoriasis or eczema. Scientists can then make quantitative assessments about how the skin is reacting to different products. It can also be used to differentiate the different kinds of skins.
The Terahertz imaging can also work well for patients with skin cancer. The rays can be used to probe the skin before starting of surgery. This will provide a clear and vivid idea of how much the tumor has spread. Skin cancer greatly affects the skin and changes its properties. Some of these properties are invisible and stay hidden below the skin’s surface. But this process changes things for the better.
Dr. Xuequan Chen, the first author of the T-rays study, says the rays are known to be sensitive to skin hydration levels. However, the cell structure of the stratum corneum is also reactive to T-ray reflections. The particular technique used by scientists enables a sensitive probing of the structure’s properties. This in turn provides precise information about human skin, making it a very useful tool for skin diagnosis.
For testing the method, scientists had the arms of volunteers placed on the imaging window of the Terahertz equipment. This was done for a duration of 30 minutes in total. After acclimatizing to the dryness and ambient atmosphere of the lab. By the holding of skin against the imaging window, water was blocked from escaping the skin through perspiration. The scientists then did 4 right angle measurements every two minutes till half an hour. This helped them monitor the effects of occlusion. As T-rays are water sensitive, scientists could see a clear difference in water accumulation inside the skin.
By these experiments, Terahertz has proven to be an effective tool to diagnose the skin like never possible before. Research is still in the process to make the method more practical and efficient.
