چکیده

This paper reports the design of a miniature, costeffective spectroscopy system for assessing tissue biochemical and morphological information using a few wavelengths. This instrument will be based on thin-film optical filters and silicon photodiodes, avoiding the use of a full spectrograph and optical fibers. The feasibility of using only 16 wavelengths to accurately extract tissue information is confirmed on physical tissue models. Also, the suitable spectral performance of some optical filters for the selection of these wavelengths is demonstrated. The reduced size of this device will make possible its integration in an endoscopic capsule.

Acquiring molecular interference functions of X-ray coherent scattering for breast tissues by combination of simulation and experimental methods

Background: Recently, it has been indicated that X-ray coherent scatter from biological tissues can be used to access signature of tissue. Some scientists are interested in studying this effect to get early detection of breast cancer. Since experimental methods for optimization are time consuming and expensive, some scientists suggest using simulation. Monte Carlo (MC) codes are the best...
