Introduction of a newly created AW stereotactic frame: a phantom-based accuracy evaluation and an initial experience in clinical usage

A new stereotactic frame was created in 2015, based on a linear algorithm. It is called Albert Wong (AW) frame. A simple AW stereo-calculator was also designed based on ExcelThe aim of this study is to test the accuracy of the AW frame by a direct head to head comparison with CRWThis is a prospective pilot cross-sectional phantom study with a total of 42 (21 for AW and 21 for CRWA comparable accuracy testing results were observed between the AW and CRWAW frame successfully demonstrated a good accuracy of 0.64 mm in phantom testing using the BL phantom by a linear algorithmic calculation. The clinical trial with three patients demonstrated definitive diagnoses and safety with its use.
