He focuses on the translation of software and hardware to clinical practice. He is currently working with researchers at Kingston General Hospital to improve multiple aspects of breast brachytherapy, including the quality of needle implant insertions, and catheter path tracking.<\/p>\n<p>His goal is to promote reproducible research in computer algorithms by publishing source code and data wherever possible. He hopes that this approach will make published computer algorithms more accessible. Other researchers would not need to invest time in reimplementing and testing algorithms, and there is no risk that there will be mistakes during the reimplementation phase.<br \/>\n<div class=\"teachpress_pub_list\"><form name=\"tppublistform\" method=\"get\"><a name=\"tppubs\" id=\"tppubs\"><\/a><\/form><div class=\"teachpress_publication_list\"><div class=\"tp_publication tp_publication_article\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Gauvin, Gabrielle;  Yeo, Caitlin T;  Ungi, Tamas;  Merchant, Shaila;  Lasso, Andras;  Jabs, Doris;  Vaughan, Thomas;  Rudan, John;  Walker, Ross;  Fichtinger, Gabor;  Engel, C.

It is a challenging procedure because of issues in localizing the seroma, needles, and catheters within the soft tissue. In this paper we present two open-source technologies based on electromagnetic tracking: a navigation system to help target needles using a tracked needle guide, and software for electromagnetic reconstruction of catheter paths. These technologies were validated phantom studies. We found that the navigation system helped a radiation oncologist to target needles more accurately than under ultrasound guidance (60 needles under each condition, 3.8 vs 3.3 mm placement error<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('75','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_75\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-file-pdf\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/labs.cs.queensu.ca\/perklab\/wp-content\/uploads\/sites\/3\/2024\/02\/Vaughan2019a_0.pdf\" title=\"https:\/\/labs.cs.queensu.ca\/perklab\/wp-content\/uploads\/sites\/3\/2024\/02\/Vaughan201[...]\" target=\"_blank\">https:\/\/labs.cs.queensu.ca\/perklab\/wp-content\/uploads\/sites\/3\/2024\/02\/Vaughan201[...]<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('75','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_conference\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Connolly, Laura;

Setting up navigation in the OR relies on the&lt;br \/&gt; <br \/>\r\nmanual interactions of a trained technician to align three-dimensional virtual views to the patient\u2019s physical position&lt;br \/&gt; <br \/>\r\nand maintain their alignment throughout surgery. This work develops automatic alignment tools to improve the&lt;br \/&gt; <br \/>\r\noperability of navigation software for lumpectomies.&lt;br \/&gt; <br \/>\r\n&lt;strong&gt;METHODS&lt;\/strong&gt;: Preset view buttons were developed to refine view setup to a single interaction. These buttons were&lt;br \/&gt; <br \/>\r\ntested by measuring the reduction in setup time and the number of manual interactions avoided through their use. An&lt;br \/&gt; <br \/>\r\nauto-center feature was created to ensure that three-dimensional models of anatomy and instruments were in the center&lt;br \/&gt; <br \/>\r\nof view throughout surgery. Recorded data from 32 lumpectomy cases were replayed and the number of auto-center&lt;br \/&gt; <br \/>\r\nview shifts was counted from the first cautery incision until the completion of the excision of cancerous tissue.&lt;br \/&gt; <br \/>\r\n&lt;strong&gt;RESULTS&lt;\/strong&gt;: View setup can now be performed in a single interaction compared to an average of 13 interactions&lt;br \/&gt; <br \/>\r\n(taking 83 seconds) when performed manually. The auto-center feature was activated an average of 33 times in the&lt;br \/&gt; cases studied (n=32).&lt;br \/&gt; <br \/>\r\n&lt;strong&gt;CONCLUSION&lt;\/strong&gt;: The auto-center feature enhances the operability of the surgical navigation system, reducing the&lt;br \/&gt; <br \/>\r\nnumber of manual interactions required by a technician during the surgery.

This work develops automatic alignment tools to improve the&lt;br \/&gt; <br \/>\r\noperability of navigation software for lumpectomies.&lt;br \/&gt; <br \/>\r\n&lt;strong&gt;METHODS&lt;\/strong&gt;: Preset view buttons were developed to refine view setup to a single interaction. These buttons were&lt;br \/&gt; <br \/>\r\ntested by measuring the reduction in setup time and the number of manual interactions avoided through their use. An&lt;br \/&gt; <br \/>\r\nauto-center feature was created to ensure that three-dimensional models of anatomy and instruments were in the center&lt;br \/&gt; <br \/>\r\nof view throughout surgery. Recorded data from 32 lumpectomy cases were replayed and the number of auto-center&lt;br \/&gt; <br \/>\r\nview shifts was counted from the first cautery incision until the completion of the excision of cancerous tissue.&lt;br \/&gt; <br \/>\r\n&lt;strong&gt;RESULTS&lt;\/strong&gt;: View setup can now be performed in a single interaction compared to an average of 13 interactions&lt;br \/&gt; <br \/>\r\n(taking 83 seconds) when performed manually. The auto-center feature was activated an average of 33 times in the&lt;br \/&gt; cases studied (n=32).&lt;br \/&gt; <br \/>\r\n&lt;strong&gt;CONCLUSION&lt;\/strong&gt;: The auto-center feature enhances the operability of the surgical navigation system, reducing the&lt;br \/&gt; <br \/>\r\nnumber of manual interactions required by a technician during the surgery. This feature along with preset camera view&lt;br \/&gt; <br \/>\r\noptions are instrumental in the shift towards a completely surgeon-operable navigated lumpectomy system.&lt;\/p&gt;<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('67','tp_abstract')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_conference\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Brastianos, Harry;  Vaughan, Thomas;  Lasso, Andras;  Westerland, Mary;  Gooding, James;  Fichtinger, Gabor;  Falkson, Conrad<\/p><p class=\"tp_pub_title\">Real Time Electromagnetic Reconstruction of Catheter Paths in Multi-Catheter Interstitial Brachytherapy: A Phantom Model <span class=\"tp_pub_type tp_  conference\">Conference<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_volume\">vol.

Further testing should be performed to optimize the measurement error threshold used for classification in the support vector &lt;\/span&gt;&lt;\/span&gt;&lt;span style=&quot;font-family:timesnewromanpsmt; font-size:10.000000pt&quot;&gt;&lt;span style=&quot;font-family:lucida sans unicode,lucida grande,sans-serif&quot;&gt;&lt;span style=&quot;font-size:10px&quot;&gt;&lt;span style=&quot;font-size:12px&quot;&gt;&lt;span style=&quot;font-family:arial,helvetica,sans-serif&quot;&gt;&lt;span style=&quot;font-family:trebuchet ms,helvetica,sans-serif&quot;&gt;machine,&lt;\/span&gt;&lt;\/span&gt;&lt;\/span&gt;&lt;\/span&gt;&lt;\/span&gt;&lt;\/span&gt;&lt;span style=&quot;font-family:trebuchet ms,helvetica,sans-serif&quot;&gt;&lt;span style=&quot;font-size:12px&quot;&gt; and improve the sensitivity of our method before application in real procedures.&amp;nbsp;&lt;\/span&gt;&lt;\/span&gt;&lt;\/p&gt; <br \/>\r\n&lt;\/div&gt; <br \/>\r\n&lt;\/div&gt; <br \/>\r\n&lt;\/div&gt;<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('128','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_128\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-file-pdf\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/labs.cs.queensu.ca\/perklab\/wp-content\/uploads\/sites\/3\/2024\/02\/Harish2017a.pdf\" title=\"https:\/\/labs.cs.queensu.ca\/perklab\/wp-content\/uploads\/sites\/3\/2024\/02\/Harish2017[...]\" target=\"_blank\">https:\/\/labs.cs.queensu.ca\/perklab\/wp-content\/uploads\/sites\/3\/2024\/02\/Harish2017[...]<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('128','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_conference\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Brastianos, Harry;  Vaughan, Thomas;  Lasso, Andras;  Westerland, Mary;  Gooding, James;  Fichtinger, Gabor;  Falkson, Conrad<\/p><p class=\"tp_pub_title\">Electromagnetic Reconstruction of Catheter Paths in Mult-Catheter Interstitial Brachytherapy: A Phantom Model. <span class=\"tp_pub_type tp_  conference\">Conference<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_booktitle\">Canadian Association of Radiation Oncology (CARO) Annual Scientific Meeting, <\/span><span class=\"tp_pub_additional_year\">2017<\/span>.<\/p><p class=\"tp_pub_menu\"><span class=\"tp_bibtex_link\"><a id=\"tp_bibtex_sh_14\" class=\"tp_show\" onclick=\"teachpress_pub_showhide('14','tp_bibtex')\" title=\"Show BibTeX entry\" style=\"cursor:pointer;\">BibTeX<\/a><\/span><\/p><div class=\"tp_bibtex\" id=\"tp_bibtex_14\" style=\"display:none;\"><div class=\"tp_bibtex_entry\"><pre>@conference{Brastianos2017a,<br \/>\r\ntitle = {Electromagnetic Reconstruction of Catheter Paths in Mult-Catheter Interstitial Brachytherapy: A Phantom Model.},<br \/>\r\nauthor = {Harry Brastianos and Thomas Vaughan and Andras Lasso and Mary Westerland and James Gooding and Gabor Fichtinger and Conrad Falkson},<br \/>\r\nyear  = {2017},<br \/>\r\ndate = {2017-01-01},<br \/>\r\nurldate = {2017-01-01},<br \/>\r\nbooktitle = {Canadian Association of Radiation Oncology (CARO) Annual Scientific Meeting},<br \/>\r\nkeywords = {},<br \/>\r\npubstate = {published},<br \/>\r\ntppubtype = {conference}<br \/>\r\n}<br \/>\r\n<\/pre><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('14','tp_bibtex')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_conference\"><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Brastianos, H;  Vaughan, Thomas;  Lasso, Andras;  Westerland, M;  Gooding, James;  Fichtinger, Gabor;  Falkson, Conrad<\/p><p class=\"tp_pub_title\">Electromagnetic tracking for catheter insertion guidance for HDR breast brachytherapy: a phantom experiment <span class=\"tp_pub_type tp_  conference\">Conference<\/span> <\/p><p class=\"tp_pub_additional\"><span class=\"tp_pub_additional_booktitle\">American Society for Radiation Oncology (ASTRO) Annual Meeting, <\/span><span class=\"tp_pub_additional_volume\">vol.
