摘要: Breast tissues like fatty and fibroglandular ones are adipose mainly and possess high scattering nature, so that they diffuse and make the light approximately uniformly distribute over the measured cross-section besides absorbing to reduce the light intensity. Strong cause-and-effect relationships exist between absorption and intensity decay, and between scattering and phase delay as well. Thereby in a diffuse optical imaging system it is a general practice to estimate absorption coefficients from the measured intensity since it reflects most of the absorption property. This study aims to illustrate that both μ a and μ s ′ images of breast can be reconstructed by only direct-current data reliably to a certain extent. Varied sets of phantom design with assigned absorption/scattering properties for inclusion and background were synthesized and image reconstructed to demonstrate this perspective. Moreover, we employed a slab-type diffuse optical imaging system with a dual-direction direct-current NIR measurement module, where reconstructed images were compared between with and without reflectance NIR data. 其他題名: Opt Quant Electron 出版者: New York: Springer US 出版日期: 2016-02-01 出處: Optical and quantum electronics, 2016-02, Vol.48 (2), Article 139 版權: Springer Science+Business Media New York 2016 識別號: ISSN: 0306-8919 識別號: EISSN: 1572-817X 識別號: DOI: 10.1007/s11082-015-0366-0
