Quantitative phase imaging of erythrocyte in epilepsy patients
Microscopy Research and Technique, 2020 AbstractThe present study focuses on the quantitative phase imaging of erythrocytes with the aim to compare the morphological differences between epilepsy patients under antiepileptic treatment, who have no other disease which may affect the erythrocyte morphology, and the healthy control group.

Magnetization transfer imaging using steady-state free precession MR sequences [PDF]
, 2010 Magnetic resonance imaging (MRI) benefits from an exceptional soft tissue contrast and is therefore an important tool for medical diagnosis. While contrast in conventional MRI is generated by protons with free mobility, magnetization transfer (MT ...

Phase calibration target for quantitative phase imaging with ptychography
Optics Express, 2016 Quantitative phase imaging (QPI) utilizes refractive index and thickness variations that lead to optical phase shifts. This gives contrast to images of transparent objects. In quantitative biology, phase images are used to accurately segment cells and calculate properties such as dry mass, volume and proliferation rate.

Preprocessing methods for quantitative phase image stitching
Biomedical Optics Express, 2021 Quantitative phase imaging of cell cultures and histopathological slides often requires measurements in large fields of view which is realized through the stitching of multiple high resolution phase maps. Due to the characteristic properties of phase images, careful preprocessing is crucial for maintaining the metrological value of the stitched phase ...

Robust Phase Unwrapping via Deep Image Prior for Quantitative Phase Imaging [PDF]
IEEE Transactions on Image Processing, 2021 Quantitative phase imaging (QPI) is an emerging label-free technique that produces images containing morphological and dynamical information without contrast agents. Unfortunately, the phase is wrapped in most imaging system. Phase unwrapping is the computational process that recovers a more informative image.
