Problems solved by technology

[0013] The present invention aims at the problems of the prior art: the evaluation of dental clinical diagnosis and treatment effect is the evaluation given by the doctor after observation, which has certain subjectivity, the accuracy is not easy to ensure, and the amount of film reading is large, which consumes manpower; it provides a method without subjectivity. A method for automatically evaluating dental clinical diagnosis and treatment effects based on periapical radiographs, which is easy to ensure accuracy and saves manpower

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] like figure 1 As shown, the dental clinical diagnosis and treatment effect evaluation method proposed by the present invention, through three-stage processing, subtraction image generation, key area extraction, treatment effect evaluation, and finally gives a reasonable and accurate judgment on the clinical diagnosis and treatment effect. Each stage of processing includes the following steps:

[0039] (1) Subtraction image generation: The acquired original image is processed to generate a subtraction image; the original image includes two periapical films of the same patient before and after treatment; specifically:

[0040] (1-1) Automatic calibration of two periapical films, the specific process is as follows:

[0041] (1-1-1) Based on the SIFT and SURF algorithms to find the matching feature point pairs in the two periapical radiographs: Since the subsequent method n...

Abstract

The invention provides a method for automatically evaluating the dental clinical diagnosis and treatment effect on the basis of a periapical film, aiming to solve the problem that the evaluation of the dental clinical diagnosis and treatment effect is an evaluation given by a doctor after the observation, certain subjectivity exists, the accuracy is not easy to guarantee, the film reading amount is large, and the labor is consumed; and the method comprises the following steps: subtraction image generation; key region extraction; and treatment effect evaluation. The method can be widely appliedto the field of computer image processing.

Description

technical field [0001] The invention relates to a method for automatically evaluating the effect of dental clinical diagnosis and treatment, in particular to a method for automatically evaluating the effect of dental clinical diagnosis and treatment based on periapical slices. Background technique [0002] Medical imaging is an image obtained in a non-invasive manner for the purpose of medical research or clinical observation, which can represent the internal tissue structure of a patient or a certain part of the patient's body. In today's highly developed medicine, medical imaging has become one of the most important adjuvant treatments in clinical medicine. [0003] Taking periapical radiographs is one of the most common examination methods and is widely used in all stages of dental treatment. Before the treatment, the doctor can observe the degree and scope of the tooth lesions through the periapical film; during the treatment, the doctor can use it to determine the scop...
