assessing absorption coefficient of hemoglobin in the breast phantom using near-infrared spectroscopy
objectives in this study, the absorption coefficient of hemoglobin (hb) was used to distinguish between normal and abnormal breast tissue. materials and methods a near-infrared source (637 nm) was transmitted from major and minor vessels of a breast phantom containing 2×, 4× concentrations of oxy- and deoxy-hb. the absorption coefficients were determined from spectrometer (sm) and powermeter (p...
متن کاملCharacterization of normal breast tissue heterogeneity using time-resolved near-infrared spectroscopy.
In recent years, extensive efforts have been made in developing near-infrared optical techniques to be used in detection and diagnosis of breast cancer. Variations in optical properties of normal breast tissue set limits to the performance of such techniques and must therefore be thoroughly examined. In this paper, we present intra- and intersubject as well as contralateral variations of optica...
متن کاملbrain near-infrared spectroscopy (nirs)
near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...
متن کاملAssessing Absorption Coefficient of Hemoglobin in the Breast Phantom Using Near-Infrared Spectroscopy
BACKGROUND Blood concentrations and oxygen saturation levels are important biomarkers for breast cancer diagnosis. OBJECTIVES In this study, the absorption coefficient of hemoglobin (Hb) was used to distinguish between normal and abnormal breast tissue. MATERIALS AND METHODS A near-infrared source (637 nm) was transmitted from major and minor vessels of a breast phantom containing 2×, 4× co...
متن کاملDetermining Blood Glucose Concentration using Near Infrared Spectroscopy: Early Findings
Introduction: Diabetes mellitus is one of the diseases that have grown dramatically in today's societies. People with diabetes should continuously measure their blood glucose level. Continuous blood glucose measurement by commonly used methods is painful and difficult. On the other hand, mobile phone can be a useful tool for accessing physicians and telemedicine services more easily. The aim of...
