Abstract: A multifunctional near-infrared orthodontic accelerator for inhibiting dental plaque formation is provided, including a bottom brace, an outer periodontal brace, an inner periodontal brace, a tooth groove disposed between the outer periodontal brace and the inner periodontal brace, and micro vibrators disposed on a side close to the tooth groove. The outer periodontal brace and the inner periodontal brace are respectively provided with a holding groove therein, which is communicated with openings facing towards the tooth groove. The holding grooves are provided with tooth cleaning bars, which are connected through universal joints and disposed linearly. The tooth cleaning bars are provided with cavities, which are provided with blue light germicidal lamps fitted to inner walls of the cavities. The outer periodontal brace and the inner periodontal brace are equipped with infrared laser lights, and outer peripheries of the tooth cleaning bars are equipped with bristle strips.

Abstract: A tomosynthesis machine allows for faster image acquisition and improved signal-to-noise by acquiring a projection attenuation data and using machine learning to identify a subset of the projection attenuation data for the production of thinner slices and/or higher resolution slices using machine learning.

Abstract: A chiller-less cooling system for cooling an interventional detector comprising a detector housing. The detector housing comprising a detector tray to which the detector is attached, a lift frame on which a driving mechanism is installed to lift up/down the detector housing, a connecting arm to connect the detector tray and the lift frame, and a cover. The cooling system comprising a heat pipes connecting the detector tray and the lift frame so as to reduce a thermal resistance between the detector tray and the lift frame and transfer more heat from the detector, an external heat sink connected with the heat pipe for reducing a thermal resistance between the lift frame and an ambient environment, and a high heat transfer coefficient device embedded into the detector tray for collecting heat leading to the heat pipe, obtaining a uniform temperature distribution, and reducing a thermal resistance of the detector tray.
