Breast Cancer Detection with Diffuse Optical Tomography
3 ACKNOWLEDGMENTS First, I would like to thank Professor Huabei Jiang, for his continuous support, trusts and precious advice during my study for the Ph.D. Professor Jiang is well-known in the field of optical tomography. His views and understandings on the research subjects are exceptional. As a professor, although his schedule is very tight, he is always available to help me on my research wh...
متن کاملA Diffuse Optical Tomography System Combined with X-ray Mammography for Improved Breast Cancer Detection
The central thesis of this dissertation states that optical imaging of diffuse tissues must be combined in co-registration with a recognized gold standard of mammographic screening, i.e. X-ray mammography, to gain wide acceptance in the clinical environment. This multi-modality imaging approach promises to overcome the deficiencies of both imaging modalities by drawing on the strengths of each....
متن کاملTomographic optical breast imaging guided by three-dimensional mammography.
We introduce a modified Tikhonov regularization method to include three-dimensional x-ray mammography as a prior in the diffuse optical tomography reconstruction. With simulations we show that the optical image reconstruction resolution and contrast are improved by implementing this x-ray-guided spatial constraint. We suggest an approach to find the optimal regularization parameters. The presen...
متن کاملDiffuse Optical Imaging
Diffuse optical imaging is a functional medical imaging modality which takes advantage of the relatively low attenuation of near-infrared light to probe the internal optical properties of tissue. The optical properties are affected by parameters related to physiology such as the concentrations of oxyand deoxyhemoglobin. Instrumentation that is used for optical imaging is generally able to measu...
متن کاملOptical mammography using diffuse optical spectroscopy for monitoring tumor response to neoadjuvant chemotherapy in women with locally advanced breast cancer.
PURPOSE Diffuse optical spectroscopy (DOS) has the potential to enable monitoring of tumor response during chemotherapy, particularly in the early stages of treatment. This study aims to assess feasibility of DOS for monitoring treatment response in HER2-negative breast cancer patients receiving neoadjuvant chemotherapy (NAC) and compare DOS with tumor response assessment by MRI. EXPERIMENTAL...
