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...

In most applications of optical computed tomography (OpCT), limited-view problems are often encountered, which can be solved to a certain extent with typical OpCT reconstructive algorithms. The concept of entropy first emerged in information theory has been introduced into OpCT algorithms, such as maximum entropy (ME) algorithms and cross entropy (CE) algorithms, which have demonstrated their s...
