Multifunctional dental scanning system

Abstract

The invention relates to a multifunctional dental scanning system which comprises an emission component, a matching degree extraction device and a rephotographing starting device. The emission component comprises an X-ray tube, an emission dose detection device and an emission dose alarm device, the emission dose detection device is arranged near the X-ray tube, the distance between the emission dose detection device and the X-ray tube is equal to preset length, the emission dose detection device is used for detecting sensed ray radiation quantity and determining corresponding emission dose based on the ray radiation quantity, and the emission dose alarm device is used for transmitting dose standard exceeding signals when the emission dose exceeds limit standards. The matching degree extraction device is used for matching a tooth image pattern with a preset tooth profile to acquire corresponding matching percent, transmitting scanning success signals when the matching percent exceeds limit, otherwise, transmitting scanning failure signals. The rephotographing starting device is used for driving the X-ray tube to execute once more X-ray emission at the same position when receiving the scanning failure signals. By the aid of the multifunctional dental scanning system, functions of a dental scanning device are effectively expanded.

Description

technical field [0001] The invention relates to the field of dental scanners, in particular to a multifunctional dental scanning system. Background technique [0002] Dental scanner, composed of X-ray tube assembly THA-M-1, X-ray tube, speed limiter, digital sensor assembly, lifting frame, manual switch, column, rotating device, laser positioner. Performance: nominal electric power 770W; X-ray tube assembly (focus 0.5); photographic tube voltage adjustment range: 66~77KV; photographic tube current adjustment range: 10mA; loading time adjustment range: adult: 10S, child: 8.8S; wing bite 2.5S+2.5S, temporomandibular joint 3.1S+3.1S. [0003] A dental scanner is a device that generates X-rays. It is mainly composed of an X-ray tube, an X-ray machine power supply, and a control circuit. The X-ray tube is composed of a cathode filament (Cathod), an anode target (Anode) and a vacuum glass tube. composition. Contents of the invention [0004] In order to solve the technical pr...

Problems solved by technology

[0004] In order to solve the technical problem that current dental scanners cannot automatically start re-scanning the same part based on the scanning quality, the present invention provides a multifunctional dental scanning system, which matches the tooth imaging pattern after targeted image processing with the preset tooth contour , to obtain the corresponding matching percentage, and when the matching percentage exceeds the limit, send a scan success signal, otherwise, send a scan failure signal to drive the X-ray tube to perform another X-ray emission of the same part; at the same time, in the targeted image During the processing, compare the contrast of the Lena map with the standard contrast with the image processed by the gamma encoding based on the segmental linear approximation method, and compare the contrast of the image block at a specific position, and adaptively determine the value of the gamma encoded image based on the multiple relationship of the contrast. The number of times the image has been gamma-encoded based on a segmented linear approximation to make it more suitable for human viewing
