Background: Reliable estimation of radiation-absorbed dose is necessary to evaluate the benefits and the risks of radiopharmaceuticals used for diagnostic or therapeutic purposes in nuclear medicine. Materiel and Methods: This study included 47 patients treated with iodine-131 for Graves’ disease. A comparative study between Geant4 Monte Carlo simulation and MIRD formalism was carried out to ev...

Surgical suits allocate a large amount of expenses to hospitals; on the other hand, they constitute a huge part of hospital revenues. Patient flow optimization in a surgical suite by omitting or reducing bottlenecks which cause loss of time is one of the key solutions in minimizing the patients’ length of stay[1] (LOS) in the system, lowering the expenses, increasing efficiency, and also enhanc...

Stochastic distribution methods were used to construct patient flow simulation sub-models such as inflow, length of stay (LoS), cost treatment (CoT) and clinical pathways (CPs). However, the inflow rate demonstrates seasonality, trend, variation due natural human-made factors. LoS, CoT CPs are determined by social-demographics factors, laboratory test results, resource availability healthcare s...

Abstract In response to the low level of automation tools used for patient transfer in hospitals and resulting shortage nursing personnel, this paper studies characteristics existing products related structural features. A machine based on static is proposed, which can achieve between a hospital bed stretcher truck. paper, overall structure has been designed detail, design analysis important tr...
