Motivation: Although 2D images lack significant information that is present in 3D modalities, they might be conveniently and efficiently used to record details about the most current state of the imaged object. The most amount of information can be gained about the changes recorded by the 2D modalities and the detailed 3D model if we fuse the information provided by both of them. In order to ac...

background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years ...

We study two models for the formation and packing of helices and sheets in globular (compact) proteins. These models, based on weighted Hamiltonian paths on a regular lattice both exhibit a first order transition between a compact high temperature phase, with no extended secondary structures, and a quasi-frozen compact phase, with secondary structures invading the whole lattice. The quasi-froze...

Purpose Evaluation of airway stenosis secondary to head and neck lesions has been performed routinely with CT scan and endoscopy (1). Endoscopy of a stenotic airway can be difficult, and can be associated with compromise of the airway (2). CT virtual endoscopy (CTVE) provides a noninvasive means of evaluating the airways while simultaneously studying the head and neck soft tissues including vas...

In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...
