A new kind of holographic microscope was created by researchers under the direction of Associate Director CHOI Wonshik of the Center for Molecular Spectroscopy and Dynamics within the Institute for Basic Science, Professor KIM Moonseok of The Catholic University of Korea, and Professor CHOI Myunghwan of Seoul National University. The new microscope reportedly has the ability to "see through" the intact skull and can image the neuronal network in a living mouse brain in high-resolution 3D without removing the skull. * A substantial amount of light energy must be delivered to the sample in order to examine its interior structures using light, and the signal reflected from the target tissue must be precisely measured. It is challenging to produce clear images in live tissues due to the numerous scattering effects and severe aberration1 that frequently happen when light strikes the cells. Light experiences repeated scattering in intricate structures like living tissue, which caus...

Clinical staff can view a patient's internal organs in real time thanks to ultrasound imaging, a safe and non-invasive window into the workings of the human body. Trained technicians use ultrasound wands and probes to manipulate sound waves into the body in order to obtain these images. The heart, lungs, and other deep organs of the patient can be seen in high resolution because to the reflection of these waves. At the moment, ultrasound imaging requires heavy, specialized equipment that is only found in medical facilities and clinics. The technology may soon be as wearable and accessible as buying Band-Aids at the drugstore thanks to a new design by MIT engineers. The engineers describe their innovative ultrasound sticker design in a study that will be published in Science today. The ultrasound sticker is a stamp-sized gadget that adheres to the skin and can continuously image inside organs for 48 hours. The devices yielded real-time, high-resolution photos of the deeper organs, i...
