introduction individual x-ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the x-ray diffraction patterns resulting from coherent scattering. the goal of this study was to introduce an optimized method for obt...

This article addresses an important current development in medical and biological imaging: the possibility of imaging soft tissue at resolutions in the micron range using hard X-rays. Challenging environments, including the cochlea, require the imaging of soft tissue structure surrounded by bone. We demonstrate that cochlear soft tissue structures can be imaged with hard X-ray phase contrast. F...

Lipomas are common benign soft tissues tumors in adults. Intrathoracic lipomas are uncommon and can develop from the bronchus, lung, mediastinum, diaphragm, and thoracic wall, intrathoracic lipomas arising from the thoracic wall being particularly rare. Thoracic or pleural lipomas originate from submesothelial layers of parietal pleura, can extend into the subpleural, pleural, or extrapleural s...

MR imaging continues to make remarkable advances, often beyond our wildest dreams. As these advances occur, I am reminded continually of the importance of technology in determining how we practice medical imaging. It is obvious that most of the pertinent anatomy and diseases of the nervous system as well of those of the head and neck region primarily involve soft tissues. Only rarely do neurolo...

background: this was a retrospective cephalometric study to develop a more precise estimation of soft tissue changes related to underlying tooth movment than simple relatioship betweenhard and soft tissues. materials and methods: the lateral cephalograms of 61 adult patients undergoing orthodontic treatment (31 = premolar extraction, 31 = nonextraction) were obtained, scanned and digitized befo...

Introduction: In orthodontics, cephalometrics plays a key role in diagnosis and treatment planning. Cephalometric radiograph is the product of a two-dimensional image of the skull in lateral view, which helps in enabling the relationship between teeth, bone, soft tissue, and empty spaces in horizontal and vertical planes of space. It also helps in evaluation, diagnosis, treatment results, and p...

the application of laser in dentistry is considered as a favorable technique for patients due to its many advantages compare to other current methods. one of the main goals in pediatric dentistry is to provide the treatment as comfortable as possible without any risks for the care. laser is being used in different pediatric dental conditions including caries detection, caries removal and cavity...
