| Summary: | 碩士 === 南台科技大學 === 電機工程系 === 101 === The hospital usually examine the human body Subcutaneous abnormal tissue, in addition to by a doctor first visual check and palpation, will need to use the Supersonic, biopsy, CT, MRI or X-ray as assist examination, some examination items more time to carry out, although some examination items has National Health Insurance , but also need to pay more expensive than charge. The research designed examination system of the use and simple to operation, don’t have many time, and non-invasive, can taken to insure safety.
The principle is the different proportions of both structural of light absorption by the abnormal tissue and normal tissue of oxy-hemoglobin and deoxy-hemoglobin, so can via infrared absorption by specific of visible light and near-infrared spectrum characteristics, use specific LED wavelength source to penetrate human tissue, different absorption of subcutaneous tissue to diffraction and scattering returns oxy-hemoglobin and deoxy-hemoglobin of light signal received via photo transistors, convert optical signals into electrical signals by the results of this received signal data to determine whether the suspected abnormal tissue, The depth of the research designed examination system can detect approximately 2 cm human tissue.
Finally homemade phantom to simulate the human epidermal normal tissue and abnormal tissue through phantom experiments to adjust the circuit characteristics in order to achieve the best research result. The research hopes to avoid detection data generated by this simple examination system, as a reference for early prevention and treatment, epidermis looks without Abnormal, the internal has already missed the prime time of early diagnosis and treatment.
