Measuring tissue dispersion using the cross-correlation of half-spectrum optical coherence tomography images
(International Society for Optics and Photonics, 2019)
In Optical Coherence tomography (OCT), dispersion mismatches cause degradation of the image resolution and are, thus, compensated accordingly. However, dispersion is specific to the material that is causing the effect and ...
Automated detection of esophageal dysplasia in in vivo optical coherence tomography images of the human esophagus
(International Society for Optics and Photonics, 2018)
Catheter-based Optical Coherence Tomography (OCT) devices allow real-time and comprehensive imaging of the human esophagus. Hence, they provide the potential to overcome some of the limitations of endoscopy and biopsy, ...
A new method for breast micro-calcification detection and characterization using digital temporal subtraction of mammogram pairs
(2019)
Breast cancer is one of the most deadly malignancies worldwide and the second leading cause of death in women. Mammography, i.e. the screening for breast cancer with x-ray imaging, has significantly improved the prognosis ...
Comparison of tissue dispersion measurement techniques based on optical coherence tomography
(2019)
The effects of dispersion on optical coherence tomography (OCT) images have long been documented. The imbalance of spectral broadening, caused by dispersion mismatches in the two arms of the OCT interferometer, can result ...
Imaging of osteoarthritic cartilage with optical coherence tomography: micron-structure and polarization sensitivity
(Optical Society of America, 1999)
Dual-angle optical coherence tomography for index of refraction estimation using rigid registration and cross-correlation
(2019)
The index of refraction (n) of materials and/or tissues depends on their physical properties and serves as a source of optical contrast in imaging. The variations of the index of refraction have also been investigated for ...
