The planning of the hip prosthesis surgical operation is usually performed manually by the surgeon, who ‘draws’ on a patient’s X-ray image the outline of the prosthetic stem in order to choose the one most suitable for the case at hand. In an attempt to give some repeatability and objectivity to the planning phase, a procedure has been devised for hip prosthesis’ stem selection based on the ext...

Regions of interest (ROIs) found on breast radiographic images are classified as either tumoral mass or normal tissue by means of a support vector machine classifier. Classification features are the coefficients resulting from the specific image representation used to encode each ROI. Pixel and wavelet image representations have already been discussed in one of our previous works. To investigat...

Fragile image watermarking could be used to authenticate a digital image due to modification or altering. A watermark is embedded into the image. When the image was modified or altered, the watermark is also altered or fragile. One of popular image format is GIF image. Some fragile watermarking algorithms are applied to the single GIF image only, none for animated images. However, we could modi...

Digital radiographic systems are gaining widespread use in many clinical applications. Digital radiographic detectors vary dramatically with respect to the technologies that they use and the particular implementation. Their performance thus varies from system to system. It is often necessary to characterize the performance of a digital radiographic or mammographic detector for optimization, des...

PURPOSE X-ray exposure should be clinically justified and each exposure should be expected to give patients benefits. Since dental radiographic examination is one of the most frequent radiological procedures, radiation hazard becomes an important public health concern. The purpose of this study was to investigate the attitude of Korean dentists about radiation safety and use of criteria for sel...

The advances in digital imaging technology in dentistry have provided an alternative to film-based radiography and have given new options to detect periodontal bone loss. The purpose of this study was to compare inverted and unprocessed digitized radiographic imaging in periodontal bone loss measurements. Thirty-five film-based periapical radiographs of patients suffering from moderate to advan...

This research work is to develop an efficient and powerful medical search engine to classify and search the radiographic medical images. It focuses on bag of visual words image representation and a similarity matching technique to represent match and retrieve the similar images. This work addresses the issues in content based image retrieval for medical images. In this system can handles differ...

abstract background: the radiographic image accuracy depends on the x-ray film information visibility. good visibility is found by good contrast. radiation exposure parameters (kvp, mas) and film processing conditions have impact on contrast. in dentistry radiography machines, exposure time and processing procedure are set by radiographer. no optimized exposure time and processing conditions ma...
