Research And Development Of Devices Based On Far Infrared And X-Ray

With the continuous progress and development of human society and the continuous improvement of the level of knowledge,the theoretical system is becoming more and more perfect,the human understanding of electromagnetic waves deepening,far infrared and X-ray is two kinds of human health and disease monitoring has an important impact on the electromagnetic spectrum,We are based on far infrared and X-ray equipment development and design,to help people improve health and improve disease detection capabilities.Far infrared is the electromagnetic wave with a wavelength range of 4-1000 microns.Wavelengths in the 4-14 micron far infrared,and human tissue in the biological cell molecules,body fluids in the water molecules in motion frequency consistent with the resonance effect can occur,the epidermal tissue internal temperature rise.Thermal effect to accelerate the synthesis of biological enzymes within the body to improve the biological enzyme activity,activation of protein and other biological macromolecules,to promote body fluid circulation,enhance the body's metabolic function,thereby enhancing the body immunity and biological tissue cell repair and regeneration,far infrared is a Life light.Because far infrared rays have therapeutic effects on certain human diseases,we have decided to develop a device for far-infrared therapy.The most critical part of far-infrared therapy equipment is far-infrared radiation materials.Carbon fiber is a new type of high temperature resistant materials.The carbon fiber sheets with different models and sizes were selected as the heating materials,and their surface temperature and far infrared spectrum were studied under different voltage,AC and DC.For the production of far infrared therapy heating plate to provide experimental support.The experimental results show that the carbon fiber board is uniform in the range of 600 * 400 mm and the voltage is 48 V and the power is DC.The infrared light in the range of 8-14?m is uniform and the strength is high,the heat distribution is uniform,the temperature is suitable,the safety factor is high,In physical therapy.X-ray phase contrast imaging technology,unlike the traditional X-ray imaging based on the absorption contrast mechanism,this new technique detects the internal structure information of the object by detecting the change in the phase of the Xtransmission object.According to the theory of complex refractive index of the object,for the hard X-ray band,the phase factor of the soft tissue composed of light elements is three orders of magnitude higher than the absorption factor,which means that in theory,the phase imaging has better image quality,better sensitivity TheAt present,the mainstream X-ray phase contrast imaging technology,including crystal interferometer,free propagation imaging,diffraction enhancement imaging,grating phase contrast imaging.Some of the device system is too complex,the field of view is too small,requires a higher mechanical stability and the harsh requirements of the light source,it is difficult to industrial applications.At present the closest clinical imaging technology is the grating phase contrast imaging technology,the technology out of dependence on the synchrotron radiation source,you can complete the experiment in ordinary laboratories.In view of the huge application prospect of X-ray contrast,this paper designs CT on phase contrast imaging based on grating phase contrast imaging technique and free propagation technique.
