AB  - Metal artifacts produce incorrect Hounsfield units and impact treatment planning 
      accuracy. This work evaluates the use of single-energy metal artifact reduction 
      (SEMAR) algorithm for treatment planning by comparison to manual artifact 
      overriding. CT datasets of in-house 3D-printed spine and pelvic phantoms with and 
      without metal insert(s) and two treated patients with metal implants were 
      analysed. CT number accuracy improved with the use of SEMAR filter: root mean 
      square deviation (RMSD) from reference (without metal) reduced by 35.4 in spine 
      and 98.8 in hip. The plan dose volume histograms (DVHs) and dosimetric 
      measurements showed comparable results. SEMAR reconstruction improved planning 
      efficiency.
