With the advancement of science and technology, various diseases’ diagnosis and treatment techniques are also constantly improving. In different imaging diagnostic techniques, ultrasound and optical imaging are the two main methods. According to the information provided by the image, it can divide into morphological imaging, functional imaging, and molecular imaging technology. One of the research fields of Professor Li Pai-Chi of the Institute is the combination of acoustic and optical detection technology, called photoacoustic imaging technology. The basic principle is to irradiate the target with a laser, and different tissues have different light absorption rates. The parts with more vital absorption rates will generate detectable ultrasonic signals through the deformation caused by thermal expansion. When ultrasonic imaging technology is used for detection, target, and non-target tissue can be distinguished. This technology happens to combine the advantages of light and sound waves: generally speaking, the contrast of optics is better, while the scattering of sound waves is weaker and the penetration is better, so in recent years, photoacoustic imaging technology has gradually gained attention, and in Bioassays are beginning to play an important role.
\nIn February 2021, Professor Li Baiqi’s team published a study on Biomedical Optics Express using photoacoustic imaging technology to perform 3D image reduction and calcium ion concentration measurement of tumor cells. In addition to imaging, Prof. Li also focuses on targeted therapy. Using the cavitation effect produced by ultrasound in the body, that is, the sound wave generates air bubbles (or other air bubbles) in human soft tissues, and Accompanying the process of sound wave imaging of bubbles, these micro-bubbles are used to coat the nano-probe and transport it to the target position, and then use the corresponding absorbed laser to heat the nanoparticles so that the affected area can be accurately heated. To sum up, the photoacoustic system has a variety of applications in biomedicine. What’s more, it can also solve the current bottlenecks encountered in medical treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"
