AB  - BACKGROUND: There are several complications associated with Stent-assisted Coil 
      Embolization (SACE) in cerebral aneurysm treatments, due to damaging operations 
      by surgeons and undesirable mechanical properties of stents. Therefore, it is 
      necessary to develop an in vitro simulator that provides both training and 
      research for evaluating the mechanical properties of stents. METHODS: A new in 
      vitro simulator for three-dimensional digital subtraction angiography was 
      constructed, followed by aneurysm models fabricated with new materials. Next, 
      this platform was used to provide training and to conduct photoelastic stress 
      analysis to evaluate the SACE technique. RESULTS: The average interaction stress 
      increasingly varied for the two different stents. Improvements for the 
      Maximum-Likelihood Expectation-Maximization method were developed to reconstruct 
      cross-sections with both thickness and stress information. CONCLUSIONS: The 
      technique presented can improve a surgeon's skills and quantify the performance 
      of stents to improve mechanical design and classification. This method can 
      contribute to three-dimensional stress and volume variation evaluation and assess 
      a surgeon's skills.
