Abstract

The embodiment of the invention discloses a dental panoramic image generation method and device and a computer readable storage medium. The method comprises the steps: obtaining a preset standard dental arch line, and determining a plurality of reconstruction points on the standard dental arch line; based on the position information of each reconstruction point, respectively determining the position information of each movement point corresponding to the dental panoramic imaging system; controlling the dental panoramic imaging system to move according to the coordinates of the movement points,and acquiring an image sequence; and carrying out superposition processing on all images in the image sequence to generate a dental panoramic image. Through the implementation of the invention, the panoramic image of the dental department is reconstructed by adopting a position synchronization mode, the image distortion and the positioning requirement on a patient are reduced, and the clear imaging of a personalized dental arch line can be effectively met.

Description

technical field [0001] The present invention relates to the technical field of medical imaging, in particular to a dental panorama image generation method, device and computer-readable storage medium. Background technique [0002] Dental panoramic imaging is one of the important detection methods for oral diseases. It is used to display the images of all teeth on one X-ray film and is widely used clinically. [0003] At present, dental panoramic imaging usually uses TDI (Time Delayed and Integration) sensors. TDI is based on multiple exposures to the same target. Through delayed integration, the collection of light energy is greatly increased, and the signal-to-noise ratio can be improved. , and can reduce the detector weight and volume. TDI requires that the frame rate of the flat panel detector be strictly synchronized with the motion rate of the target during scanning, and the panorama image can be obtained by panning and superimposing the collected images according to t...
