Ameloblastic fibroma (AF) is a benign tumor of mixed odontogenic origin, which affects predominantly young individuals. AF appearing as a mixed radiographic image is very rare. This report describes a case of AF in a 12-year-old male identified during a routine radiographic exam for orthodontic treatment planning. The panoramic radiography revealed a well-defined multilocular mixed image locate...

background: breast is one of the main radiological sensitive organs, hence it is important to evaluate absorbed dose to this organ especially to the glandular parts. it is the aim of this study to measure mean glandular dose and image contrast in terms of different mammographic parameters. materials and methods: in this study two mammography machines located at said-al shohada (giotto) and shah...

Introduction: Content Based Image Retrieval (CBIR) is a method of image searching and retrieval in a  database. In medical applications, CBIR is a tool used by physicians to compare the previous and current  medical images associated with patients pathological conditions. As the volume of pictorial information  stored in medical image databases is in progress, efficient image indexing and retri...

Computed tomography (CT) was first developed to measure accurately radiographic density, rather than as a method of imaging. Although subsequent development concentrated on the imaging potential of the method, some recent studies have used the ability of the method to quantify radiographic density, to provide precise measurements of lung regions and infer differences in regional properties. CT ...

An application of machine vision, incorporating neural networks, which aims to fully automate real-time radiographic inspection in welding processes is described. The current methodology adopted comprises two distinct stages the segmentation of the weld from the background content of the radiographic image, and the segmentation of suspect defect areas inside the weld region itself. In the first...

Purpose With the development of digital X-ray imaging and processing methods, the categorization and analysis of massive digital radiographic images need to be automatically finished. What is crucial in this processing is the automatic retrieval and recognition of radiographic position. To address these concerns, we developed an automatic method to identify a patient's position and body region ...

The prime purpose of this project was to develop and evaluate a method to digitally alter the dynamic range of digital radiographic images. This digital manipulation of the dynamic range can achieve alteration of the displayed contrast and brightness of the digital radiographic image, based on the underlying anatomy within the image. So-called anatomically shaped radiographic contrast-enhanceme...
