Optical diffraction tomography is a powerful technique to produce 3D volumetric images of biological samples using contrast produced by variations in the index of refraction in an unlabeled specimen. While this is typically performed with coherent il

Quantitative oblique back-illumination microscopy (qOBM) is an emerging label-free optical imaging technology that enables 3D, tomographic quantitative phase imaging (QPI) with epi-illumination in thick scattering samples. In this work, we present a

We demonstrate a fiber-based quantitative phase imaging (QPI) system with epi-illumination to acquire tissue and cellar level structure. Our approach is based on quantitative oblique back-illumination microscopy (qOBM), which keeps the advantages of

The first-line treatment for brain cancer is surgery, which focuses on maximizing the percentage of the tumor removed during surgery (i.e., extent of resection) while minimizing damage to healthy brain tissue. Data show that extent of resection is on

Brain tumor surgery involves a delicate balance between maximizing the extent of tumor resection while minimizing damage to healthy brain tissue that is vital for neurological function. However, differentiating between tumor, particularly infiltrativ

We have recently developed quantitative oblique back-illumination microscopy (qOBM), which enables full-field quantitative phase imaging (QPI) of objects embedded in a thick scattering medium. This epi-mode technique makes use of multiple scattering

Background Umbilical cord blood has become an important source of hematopoietic stem and progenitor cells for therapeutic applications. However, cord blood banking (CBB) grapples with issues related to economic viability, partially due to high discar
