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 o

Embodiment Construction

[0019] Embodiments of the multifunctional dental scanning system of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Dental scanner power supply can be divided into high-voltage power supply and filament power supply. The filament power supply is used to heat the filament. The high-voltage output terminals of the high-voltage power supply are respectively clamped at both ends of the cathode filament and the anode target to provide a high-voltage electric field to make the filament active. The electrons accelerate to the anode target to form a high-speed electron flow. After bombarding the anode target surface, 99% of them are converted into heat, and 1% of them are generated by bremsstrahlung to produce X-rays.

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...
