BACKGROUND: In this study, we want to automatically diagnose mandibular fractures using a diagnostic algorithm without using direct intervention. Using a smart system in detection of the mandibular fracture, we have responded to this challenge, in this work. The purpose of this paper is detection of the mandibular fracture with processing image using particle swarm optimization (PSO) algorithm in the panoramic images that facilitate conducting a more accurate diagnosis.
METHODS: Particle swarm optimization, in principle, is a computing evolutionary technique and an optimization population-based method. This algorithm is based on examination of the color changes around the fracture in the panoramic images. The color of the fracture around bone is darker (lucent) compared with that of the bone (opaque). Methodology of this algorithm on panoramic image is to investigate the color changes around bone and to show mandibular fracture. The difference between this study and previous ones is computation of the color changes by image processing algorithm for diagnosis of the mandibular fracture.
RESULTS: After running the algorithm, if the fracture around bone, PSO algorithm can recognize mandibular fracture and identify its location.
CONCLUSIONS: This algorithm provides useful and successful results for the presented tests and experiments. Using this algorithm, it is possible to save time, reduce errors, and have a more accurate diagnosis. Among the potential applications of this algorithm is to intelligently help dentist robots.
