conclusion there is still excessive unjustified concern of pte in less trained physicians leading to excessive diagnostic work-up. loyalty to the existing guideline for management of suspected pte in educational hospitals and supervision of attending physicians could prevent overuse of ctpa. results during a 6-month period, 82 patients who underwent ctpa were included. the prevalence of pte was...
background: proper rotation of components in total knee arthroplasty (tka) will largely affect the postoperative outcome. ethnical variation may affect rotational profile. we aimed to evaluate distal femur rotation in iranian population using transepicondylar axes. methods : from a total of 450 knee ct scans and via consecutive sampling, 150 qualified subjects with normal lower extremities al...
Iterative Algorithms can obtain good reconstruction image for enough Iterative times in the technique ct image reconstruction. The order method of the Weighted Distance Orthogonal (WDO) is introduced in this paper to accelerate the Iterative reconstruction, which improves greatly the access mode of ART to projection data, based on the crucial effect that the access order of projection date has ...
As the Computed Tomography (CT) requires normally hundreds of projections to reconstruct the image, patients are exposed to more X-ray energy, which may cause side effects such as cancer. Even when the variability of the particles in the object is very less, the Computed Tomography requires many projections for good quality reconstruction. Discrete Tomography makes use of less variability of th...
