On January 17, 2024, Professor Chulhong Kim from Pohang University of Science and Technology (POSTECH), South Korea, accepted an invitation from Academician Hairong Zheng and Researcher Chengbo Liu of the Shenzhen Institutes of Advanced Technology (SIAT), Chinese Academy of Sciences, to participate in the 2024 IFMBE Asia-Pacific Regional Biomedical Frontier Symposium and visit the photoacoustic imaging laboratory for academic exchange. During the event, he delivered a lecture titled “Multimodal Imaging: Photoacoustic Imaging Plus More”. Ultrasound and optical imaging instruments are widely used in diverse biological and medical applications. In particular, multimodal implementations combining light and sound have been actively studied to enhance imaging quality.

In his presentation, Professor Chulhong Kim first introduced a four-modal fusion imaging system (modalities: ultrasound, photoacoustic, optical coherence tomography (OCT), and fluorescence). This system employs a spherically focused transparent ultrasound transducer to achieve seamless integration of ultrasound imaging with photoacoustic imaging, OCT, and fluorescence imaging. Additionally, he outlined the eight-step fabrication process of the spherically focused transparent ultrasound transducer and highlighted the eight key features of this fusion imaging system. Finally, he validated the feasibility of the quadruple fusion imaging system through multimodal imaging of two models (rat eyeball and tumor).
