Abstract

The present invention discloses an imaging device for non-destructive detection of dental hard tissue diseases. Light emitted by near-infrared light sources collimated by collimating adjustment mirrors is projected to liquid crystal optical modulators, a computer adjusts light intensity of the liquid crystal optical modulators according to image information acquired by an optical image detecting system, the adjusted light passes through optical fiber collimating devices to be projected on both sides of a tooth to be tested; and the optical image detecting system acquires lesion information onboth sides of the tooth to be tested and uploads the lesion information to the computer, and the computer displays the lesion information. The used device can reduce radiation damage and improve sharpness of imaging, and improves prevention and treatment effects of the dental diseases.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an imaging device for nondestructive detection of dental hard tissue diseases. Background technique [0002] In dental medical institutions, medical personnel often use X-ray photography technology to detect and diagnose dental hard tissue lesions. However, when X-rays irradiate living tissues, biological cells are easily destroyed or even die. In order to prevent secondary damage to dental patients The dose of X-rays must be controlled within a certain limited range, and the number of photographs is limited. In addition, the X-ray device must have protective equipment to prevent doctors from being harmed by long-term radiation, and X-ray photography is not reliable in early caries detection. [0003] Near-infrared light can easily penetrate tooth enamel without radiation hazards, and can be used for daily non-destructive examination of dental diseases (such as early car...
