Abstract

The invention discloses a virtual digital DR image generation method. The method comprises the following steps: constructing a DR digital object; constructing an X-ray energy spectrum curve emitted by a bulb tube; constructing a filtering material attenuation model; calculating the filtered X-ray energy spectrum; and calculating to obtain a virtual digital DR image by taking the DR digital object as a virtual scanning sample. The original atlas range can be broken through, that is, the DR digital human body or the DR digital object is used as a scanning sample, the DR images under different qualities and quantities of X-ray parameters and different body positions and different radiation fields are obtained, the DRs with different contrast ratios and signal-to-noise ratios are obtained in real time, and the method has wide application value.

Description

technical field [0001] The invention relates to the technical field of DR simulation, in particular to a method for generating a virtual digital DR image and a DR virtual simulation instrument. Background technique [0002] A digital twin is a virtual entity constructed in a virtual space to represent the real-time operating state of a physical entity. It has a full range of functions that integrate geometric modeling, simulation, and data analysis, and plays the role of comprehensive analysis and decision-making. In digital twin technology, the simulation of physical entity shape, known (or empirical) physical law and unknown physical law is realized through the construction of geometric model, mechanism model and data model respectively. In 2017 and 2018, the digital twin was rated as one of the top ten technologies that will affect the future by Gartner for two consecutive years. It has been and will gradually be used in the verification, design, testing, and maintenance ...
