Abstract

The invention discloses a low-dosage digital X-ray image shelter and relates to a three-dimensional CT (computed tomography) image reconstruction model based on compressed sensing. Temporal and spatial continuous signals may be converted into a group of temporal and spatial discrete numerical sequences by sampling, sampling is carried out by Nyquist-Shannon sampling theorem, and all information in an original signal can be retained when sampling frequency is twice (5-10 times in practical application) as high as the highest frequency of the original signal. Through compressed sensing technology, sampling frequency can be reduced as far as possible to reduce irradiation dosage, at the premise of ensuring CT reconstruction quality.

Description

technical field [0001] The invention relates to a medical device, more specifically, the invention relates to a low-dose digital X-ray imaging shelter. Background technique [0002] The brutality of modern wars, the particularity of military missions, and the frequent occurrence of disaster relief have put forward higher requirements for the rapid treatment of the wounded and sick. At present, our military's medical support units at all levels must rely on new equipment to provide fast and safe treatment. In order to achieve such capabilities in wartime or non-military mission medical support, the most urgent task is to make the new generation of medical support "seamlessly linked" with actual combat support needs. In recent years, the digitization and informatization level of our army's medical equipment system has been continuously improved, and a number of advanced medical equipment such as field shelters, hospital ships, and train hospitals have come out one after anoth...
