Quantitative Phase Imaging and Artificial Intelligence

Hosted By: Molecular Probes and Nanobio-optics Technical Group

15 September 2022, 10:00 - 11:00 - Eastern Time (US & Canada) (UTC - 05:00)

Quantitative phase imaging (QPI) uses refractive indexes (RIs) as intrinsic imaging contrasts for label-free imaging. Optical diffraction tomography (ODT), also known as holotomography (HT), is one of the 3D QPI techniques. ODT is optical analogous to X-ray computed tomography; multiple 2D holograms of a sample are measured with various illumination angles, from which a 3D RI distribution of the sample is reconstructed by inversely solving the wave equation.

When the label-free and quantitative 3D imaging capability of ODT are combined with machine learning approaches, it can provide synergistic capability in bioimaging and clinical diagnosis. In this webinar hosted by the Molecular Probes and Nanobio-Optics Technical Group, Dr. YongKeun (Paul) Park from KAIST will discuss the potentials and challenges of combining QPI and artificial intelligence in terms of various aspects of imaging and analysis, including segmentation, classification, and imaging inference.
