WitrynaA CT scanner includes a stationary gantry (C) having an examination region (12) centrally therein. A rotating frame or gantry (C) which is mounted for rotation about the examination region carries an x-ray tube assembly (B), a liquid-to-liquid heat exchanger (34), and a liquid-to-air heat exchanger (48) around a peripheral edge thereof. A first … WitrynaObviously, in clinical scanning the technical parameters are changed to account for the body habitus as the image quality of the CT scan would be much worse of the larger phantom at the same dose. This is just one example to demonstrate that there is a dependence of the radiation dose absorbed on the size of the object in the scanner. popular haircuts 2016 womenWitrynaFor over 40 years, Cold Shot Chillers® has designed and manufactured high-reliability CT Chillers and CT Chiller Systems.For efficient cooling of your CT scanners, you … popular hack and slash games
