\r\nNavigated lumpectomy seeks to improve on the traditional technique by employing computer guidance to achieve the<br \/> 
\r\ncomplete excision of the cancer with optimal retention of healthy tissue. Setting up navigation in the OR relies on the<br \/> 
\r\nmanual interactions of a trained technician to align three-dimensional virtual views to the patient\u2019s physical position<br \/>

\r\noperability of navigation software for lumpectomies.<br \/> 
\r\n<strong>METHODS<\/strong>: Preset view buttons were developed to refine view setup to a single interaction. These buttons were<br \/> 
\r\ntested by measuring the reduction in setup time and the number of manual interactions avoided through their use. An<br \/> 
\r\nauto-center feature was created to ensure that three-dimensional models of anatomy and instruments were in the center<br \/>

\r\nview shifts was counted from the first cautery incision until the completion of the excision of cancerous tissue.<br \/> 
\r\n<strong>RESULTS<\/strong>: View setup can now be performed in a single interaction compared to an average of 13 interactions<br \/> 
\r\n(taking 83 seconds) when performed manually. The auto-center feature was activated an average of 33 times in the<br \/> cases studied (n=32).<br \/>
