A digital upgrade device for a film-type panoramic dental X-ray machine

Abstract

The invention relates to a digital upgrade device for a film-type panoramic dental X-ray apparatus and belongs to the technical field of digitalization of medical instruments. The digital upgrade device comprises a film cartridge speed scanner, a TDI CCD (time delayed and integration, charge coupled devices) based X-ray detector, a video signal AD (analog to digital) conversion uploader, a PC (personal computer) display platform and a power source. The film cartridge speed scanner is used for scanning movement of a scanning film cartridge of the existing film-type panoramic dental X-ray apparatus; a scanned speed signal is transmitted to the TDI CCD based X-ray detector; a processed movement signal drives internal charge of a sensor TDI CDD to transit; an output signal of the X-ray detector enters the video signal AD conversion uploader and is subjected to analog-to-digital conversion and transmitted to the PC display platform; the PC display platform stores and displays a file subjected to analog-to-digital conversion. The digital upgrade device has the advantages that the domestic existing film-type dental panoramic apparatus is digitally upgraded, cost is saved, and cooperation with domestic manufacturers of existing film-type dental panoramic apparatuses to provide technical support is available.

Description

technical field [0001] The invention relates to a digital upgrading device of an X-ray machine, in particular to a digital upgrading device of a film type panoramic dental X-ray machine. Background technique [0002] Dental panoramic X-ray imaging equipment is widely used in hospital oral diagnosis and treatment. It can take pictures of the whole mouth of the human body and obtain tomographic images of teeth, periodontal tissues and their adjacent anatomical structures. According to different X-ray receivers, dental panoramic X-ray imaging equipment can be divided into film cassette type X-ray panoramic machine, IP plate imaging X-ray panoramic machine and charge-coupled device type X-ray panoramic machine. The film cassette type X-ray panoramic machine is the most traditional imaging method. It consists of an intensifying screen, a photosensitive film and a cassette. It needs to go through the steps of developing, fixing, washing and drying to obtain images. The operation i...

Problems solved by technology

The film cassette type X-ray panoramic machine is the most traditional imaging method. It consists of an intensifying screen, a photosensitive film and a cassette. It needs to go through the steps of developing, fixing, washing and drying to obtain images. The operation is complicated and has certain chemical pollution; The IP plate imaging X-ray panoramic machine is an indirect imaging method, which needs to scan the IP plate through a laser scanner to obtain a digital image. Although it does not need to be processed to improve efficiency, the operation is still complicated, time-consuming, and the radiation dose is large; digitalization The X-ray panoramic machine can directly convert the received X-rays into image data, without chemical processing in the darkroom, fast imaging speed, higher imaging resolution, and smaller radiation dose
