AB  - The aim of this study is to evaluate the impact of anisotropic analytical 
      algorithm (AAA) and 2 reporting systems (AXB-D(m) and AXB-D(w)) of Acuros XB 
      algorithm (AXB) on clinical plans of nasopharyngeal patients using 
      intensity-modulated radiotherapy (IMRT) and RapidArc (RA) techniques. Six plans 
      of different algorithm-technique combinations are performed for 10 patients to 
      calculate dose-volume histogram (DVH) physical parameters for planning target 
      volumes (PTVs) and organs at risk (OARs). The number of monitor units (MUs) and 
      calculation time are also determined. Good coverage is reported for all 
      algorithm-technique combination plans without exceeding the tolerance for OARs. 
      Regardless of the algorithm, RA plans persistently reported higher D(2%) values 
      for PTV-70. All IMRT plans reported higher number of MUs (especially with AXB) 
      than did RA plans. AAA-IMRT produced the minimum calculation time of all plans. 
      Major differences between the investigated algorithm-technique combinations are 
      reported only for the number of MUs and calculation time parameters. In terms of 
      these 2 parameters, it is recommended to employ AXB in calculating RA plans and 
      AAA in calculating IMRT plans to achieve minimum calculation times at reduced 
      number of MUs.
