When lightning strikes, you can hear the sound of thunder belatedly after a few seconds. It is a'photoacoustic' phenomenon in which the material surrounding the lightning absorbs light and turns into heat, causing the material to expand and generate sound. Scientists have recently applied this principle to the body, making high-precision ultrasound and using it to observe the body.The bio-photoacoustic medical imaging laboratory, led by Professor Chul-Hong Kim of the Department of Creative IT Convergence Engineering, is developing photoacoustic technology that lets you see through the body by striking lightning in the body. Through photoacoustic technology, it is making an early diagnosis of cancer by looking into every corner. As the technology can be applied to low-cost ultrasound devices as it is, it is also speeding up the development of equipment by taking advantage of the advantages that can be easily applied to various clinics. In recent years, it is pursuing commercialization by developing next-generation medical imaging technology using artificial intelligence (AI)-based ultrasound and photoacoustic technology, and applying it to clinical practice. Photoacoustics is a technology that takes ultrasonic technology to the next level. Ultrasound makes sound into a machine, and then measures the sound coming back to determine the structure of an object. Photoacoustics uses lasers instead of ultrasonics to make ultrasonic waves in the body and measure them to maximize sensitivity. Existing ultrasound is difficult to diagnose, so expensive equipment such as computed tomography (CT) and magnetic resonance imaging (MRI) or that require radiation exposure are additionally followed. Using photoacoustic equipment, it is possible to diagnose diseases without additional diagnosis.
