With the advance of multimedia technologies in general and diagnostic images technologies specifically, the number of radiographic images is constantly escalating in the biomedical field. This field demands sophisticated systems for management and effective search and retrieval of the radiographic images produced. This paper presents a semantic content-based radiographic image retrieval system ...

this study was a part of national project to establish and optimize local and national diagnostic guidance levels. this work intends to evaluate image quality and entrance surface air kerma (esak) for patients' radiographic examinations in two north western provinces of country. two hospitals got involved in the present study. the rate of the rejected images and image quality grades were determ...

IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...

Radiographic image is the final product of imaging department and it passes through many steps before viewing. To achieve the ideal images with high quality and lowest possible radiation dose to the patient, one should take care during each stage of image formation which isn’t only practiced by one person who is designated to do that, It is the responsibility of everybody in the facility to imp...

With the advance of multimedia and diagnostic images technologies, the number of radiographic images is increasing constantly. The medical field demands sophisticated systems for search and retrieval of the produced multimedia document. This paper presents an ongoing research that focuses on the semantic content of radiographic image documents to facilitate semantic-based radiographic image ind...

Real-time digital radiography is an important developmental tendency for radiographic inspection and diagnosis technique, and enhancement of image is the key to improve resolution and sensitivity of radiographic inspection. In this paper, the algorithm and character of Rank-Order filter is discussed with great emphasis. Rank-Order filter is one of nonlinear filter, All the methods are used to p...
