Optical Imaging for Human Body Medical Analysis Using Polychromatic Infrared LED 700-1100nm.

In the medical field, the role of human body imaging is very important because it can provide a picture of the condition of human body organs that can show the severity level of an illness of the human body. It is very important, such that a patient must be taken of his or her body imaging before the next medical action to be conducted. Currently, human body imaging that is mostly done in the medical field is using a high-energy beam which can damage the body such as SPECT, PET, MRI, and X-rays. Therefore, it is necessary to develop another imaging technology to avoid damage to organs due to the usage of excessively high energy beam. One alternative method used is near-infrared optical imaging, which is less body damage effect, non-ionizing, less dangerous and low-cost. In optical imaging based on near infrared, the images are taken several times in different wavelengths. Each single wavelength is expected to experience different optical phenomena, such as absorption, scattering, and reflection or transmittance. Therefore, a different wavelength is expected to result in different image contrast. The image contrast differences of multiple images are expected to give us contrast selectivity of the object. The range of infrared spectral wavelengths enables good contrast and selectivity, therefore, it can help us to identify, distinguish and provide clear imaging of tissues, such as bones, muscle tissue, meat and tumors or cancer. The authors carried out the development of near infrared-based optical imaging characterization in the spectral region of 700–110nm to analyze the selectivity of absorption and transparency of light wavelengths in body organ tissues. The research object is limited to the palm and finger joints of the human hand. Determination of the level of contrast and saturation image processing is done by using Adobe Lightroom 6.8 software. This software helps in such a way that a good level of contrast selectivity can be obtained, therefore the image of the intended body’s tissue can be shown sharper. In this paper, we show that near infrared wavelength between 700 and 1100nm is suitable and very promising for visualizing parts of the human body without harming and giving bad effects to the body.
