Evaluation of image reconstruction algorithms in cone-Beam computed tomography techniqueDiscussion From the obtained results, the quality of the image reconstructed by both two algorithms increases and its noise decreases as the number of projected images increases. However, with the same number of projections, contrast of reconstructed images using the SIRT are better than FDK (FDK) algorithm. With a small number of projectio...

Comparison and evaluation for the dose distribution and physical characteristics between two aaa and axb algorithms in eclipse v13.6 software on treatment plans in regions heterogenous densities at 108 military central hospitalCONCLUSIONS The time advantage should use AAA algorithm to calculate the dose to improve working efficiency. However, with tumors located near the air sinus or close to the skin, use the AXB algorithm to calculate the dose. For thorax area, we will prioritize the use of AXB algorithm to calculate the dose. This is consistent with previously...

Effect of fluid bolus triggers and their combination on fluid responsiveness in optimization phase of severe sepasis and septic shock resuscitationIn optimization phase, fluid is usually administered upon clinical signs that suggest of hypovolemia, i.e. fluid triggers. Among these triggers, tachycardia was the most common used in our study. In a mcta-analysis about diagnostic value of vital signs in hypovolemic state, heart rate > 100 bpm had a very high specificity in revealing hypovolemia d...
