Embodiment Construction

[0029] The technical solutions will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] A method for detecting and judging materials of cultural relics based on medical CT disclosed by the present invention comprises the following steps:

[0031] A. Adjust the parameters of medical CT: make the scanning focus on the measured cultural relics and improve the resolution of the reconstructed image through the thickness, layer distance or field of view; B. Calibrate the CT value of the water model: determine whether the machine needs to be corrected; The machines determine their respective CT referenc...

Abstract

The invention relates to the field of non-destructive testing, and solves the technical problem in the prior art that scientific detection cannot be easily carried out on a small-sized removable cultural relic. A medical CT (Computed Tomography)-based cultural relic material detecting and determining method is characterized by comprising the following steps: A, carrying out parameter adjusting andoptimizing on a medical CT; B, scanning a water mold and carrying out CT value calibration; C, carrying out CT irradiation; D, processing data; E, outputting a result. According to the medical CT-based cultural relic material detecting and determining method and detecting device, disclosed by the invention, cultural relic detection is carried out by utilizing an existing advanced imaging means ofthe medical CT and an image processing technology; an inner structure of a three-dimensional object can be accurately described through non-contact accurate scanning, so that the density distributioncan be quantitatively determined, and three-dimensional reconstruction, local amplification, detail contrast and the like can be carried out; the cultural relic detection can be fast, credible and more visualized and convenient.

Description

technical field [0001] The invention relates to the field of non-destructive testing, in particular to a medical CT-based material detection and determination method and detection device for cultural relics. Background technique [0002] The identification of counterfeit Chinese cultural relics and ancient artifacts is the primary task of the cultural relics, archaeology, collection and antique business circles. Generally speaking, people distinguish the authenticity of ancient utensils from three aspects: ancient material, processing technology and artistic style. At present, the collection and even the archaeological circles are still mainly identified based on visual experience. In order to draw more objective and reliable conclusions, non-destructive testing is widely used in the identification of ancient artifacts. [0003] Cultural relics have high ornamental value and economic value because of their special overall attributes, which determines that it is impossible t...
