purpose: to recognize affective factors in delivering x-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells.   materials and methods: since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). x-ray imaging was done to determine geometric features of liver.   results: radio...

Virtual learning environments (VLEs) have numerous possibilities for the use of their tools and can assist in processes teaching about radiographic image interpretation. This study aimed to evaluate a virtual environment as support material students discipline Dental Radiology. interpretation was conducted contribute knowledge training changes tooth adjacent bone tissue, visualized periapical i...

cent hemithorax is seen at frontal chest radiography are often encountered. Because such an abnormality is related to various conditions, including radiographic artifacts, chest wall abnormalities, pulmonary vascular disorders with reduced perfusion, and lung parenchymal abnormalities with air trapping or compensatory overexpansion, a radiographic finding of increased radiolucency involving one...

BACKGROUND AND AIMS In periapical radiographic technique, the changes will be visible only after considerable deposi-tion or resorption while digital subtraction technique visualizes slight density changes. This study was aimed to compare visualization of density changes in conventional periapical radiographs and digital subtraction technique with or without image enhancement. MATERIALS AND M...

the akhal-teke is an ancient horse originat-ing from asia where it was used by nomadic tribes and used as a warhorse. lameness examinations require proper interpretation of clinical and radiographic findings. therefore, understanding of normal radiographic findings of the foot is necessary. although the radiographic appearance of the normal foot must be understood to recognize abnormalities ,th...

in this paper a novel fuzzy scheme for medical x-ray image classification is presented. in this method, any image is partitioned in to 25 overlapping subimages and then shape-texture features are extracted from shape and directional information extracted from any subimage. in the classification stage, we apply a fuzzy membership to any subimage with respect to euclidean distance between feature...
