Korean Scientists Innovate Non-Invasive Brain Imaging Through Mouse Skulls 🧠

A lot of people worry about the radiation we're exposed to when we get X-rays and CT scans.<br />For that reason, Korean researchers have been working on a new way to look inside the body using light waves.<br />Park Se-young has more. <br /> Being able to safely and accurately look inside the body is essential for both diagnosis and treatment of diseases.<br />Light can provide high resolution images without harming the body, but light's trajectory is easily scattered and diffused.<br />Now, Korean researchers have found a strategy to maximize the intensity of the waves that interact with the target over the waves that do not, … based on the time it takes for the waves to travel to the target and be reflected back. <br />After selecting the correct wavelengths, the researchers shoot the light toward the target once again to maximize efficiency.<br /><br /> "After analyzing the characteristics of light waves that interact with the target object, we developed a technique that increases the efficiency by using a special pattern of light."<br /><br />When the scientists applied the technique to a mouse skull, it demonstrated a more than ten-fold improvement of light energy delivery to targets compared to current optical imaging.<br /> The team expects the method to increase the efficiency of disease control and hopes to apply it to nerve cells, bone marrow and brain tissue of animals and humans.<br />Park Se-young, Arirang News. <br />
