|Accessory; Breast Tissue||Device: Diffuse Optical Spectroscopy|
Diffuse Optical Spectroscopic Imaging a new method for quantitative characterization of the optical properties of tissues. The diagnostic tools utilize anomalies in the transmission of diffusing near infra-red light for the rapid detection of oxygenated and deoxygenated hemoglobin, near infra-red absorbing drug levels, blood volume changes, and scattering properties in tissues.
Diffuse Optical Spectroscopic Imaging measurements of breast tissue optical properties probe is similar in shape to an ultrasound probe. The imaging can measurements on different areas of the breast including diseased location and normal area. Optical measurements can guided by co-registered ultrasound measurements for the purpose of determining lesion size and location. Each measurement will require about 5-60 seconds to record the data and calculate optical properties. The process will be repeated until an adequate number of measurements are performed and measurements take 30 to 90 minutes.
The researcher can determine that breast optical properties on demographic information, such as age and menopausal status as well as medical history.
