متن کاملResearch on Defect Depth Measurement Algorithm In Digital Radiography Testing
The defect depth had always been difficult to measure in the regular Radiographic Testing in the past, but can be accurately measured in Digital Radiographic image grayscale by the digital image processing technology. In the paper, the corresponding relation between the digital image grayscale value of the welding defect and the X-ray strength, was analyzed by means of Beer Theorem, and an algo...
متن کاملEvaluation of Image Magnification in Digital Panoramic Radiography
Introdouction: The aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. Materials and methods: In this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. Implant diameter and length were measured on pan...
متن کاملEffective Dose Evaluation of Critical Organes in Digital Radiography Exames
Background and Aim: Due to the increasing number of radiographic tests, TLD dosimeters can be used to measure the effective dose of critical organs in various radiographic tests. In this research, the progression of analogue to digital radiology devices, which facilitates and accelerates the performance of radiographs, especially emergency patients, was investigated, and then the effective dose...
متن کاملDigital rotational radiography in neuroradiology.
Different angiographic techniques (e.g., multiple oblique views, angiotomography, and magnification angiography) have been proposed to improve the diagnosis of cerebral vascular malformations and occlusive diseases. However, these methods are either time-consuming or necessitate repeated injections of contrast medium. The common goals of all these techniques are (1) to achieve a documentation o...
