Developments in digital radiography (DR) may have held the high ground of x-ray imaging on the RSNA exhibit floor this year, but technical improvements in surgical C-arms, conventional radiography/fluoroscopy, and angiography equipment were exciting, even extraordinary in some cases. Advanced software applications in x-ray have flourished as well, particularly in 3D imaging and digital displays...

orthopantomography is a well-established imaging technique in dental diagnosis. although its exposure to individuals is relatively low compared to other diagnostic radiology examinations, it is still the most frequent x-ray examination. so it is important to estimate absorbed dose to critical organs in this examination. the present study was designed to determine the radiation doses to eyes, pa...

Introduction One of the best methods in the diagnosis and control of breast cancer is mammography. The importance of mammography is directly related to its value in the detection of breast cancer in the early stages, which leads to a more effective treatment. The purpose of this article was to calculate the X-ray spectrum in a mammography system with Monte Carlo codes, including MCNPX and MCNP5...

this study was conducted to compare the mandibular bone density between postmenopausal women with normal skeletal bone mass density (bmd) and those with low skeletal bmd using digital panoramic radiographs.one hundred fifteen postmenopausal women were divided into normal and osteoporotic/osteopenic groups. digital panoramic radiographs were prepared using digora pct sorodex equipment and promax...

background: the sporadic cases of radiation-activated multiple sclerosis (ms) has been previously described, with a few studies focused on the relationship between radiation and the risk of ms. the aim of our study was to evaluate the association between history of x-ray radiation and ms.   methods : this case-control study was conducted on 150 individuals including 65 ms patients and 85 age- a...
