MRI image overlay

A large and growing family of medical interventions involves the placement of some linear surgical instruments. Typical examples include needle based aspirations, injections, local ablation therapies, brachytherapy, but “virtual needles” like high energy X-ray and laser beams are also commonly applied. The majority of these interventions today are performed percutaneously (i.e., across the skin). Recently, a rapidly growing variety of these procedures have been deployed via alternative access routes from within body cavities (rectum, sinus, throat), as well as the vascular and gastro-intestinal systems. Typical guidance methods are computed tomography, ultrasound, magnetic resonance imaging, and fluoroscopy. Our lab focuses on development of enabling technology for image-guided percutaneous and intra-cavity procedures. An important aspect of our research is translation of these systems and technologies to clinical trials, through partnership with world-class clinical experts and industry partners in Canada, U.S.A, and beyond... read more

Perk Lab receives partnership development fund with the University of Western Australia

The Perk Lab received a partnership development fund with Dr. Karol Miller (Intelligent Systems for Medicine Laboratory, University of Western Australia) under the Queen’s Visitors to Partner Institutions of the Matariki Network of Universities program.

New PhD in the Perk Lab: Dr. Helen Xu


Helen Xu has defended her PhD today, entitled "Target Localization in MRI-guided Prostate Biopsy". Helen gave an excellent presentation, handled the grilling admirably; and altogether passed with a high banner. 


Jennifer Andrea wins Ontario/Baden-Württemberg Summer Research Fellowship

Jennifer Andrea

Jennifer Andrea received an Ontario/Baden-Württemberg Summer Research Fellowship to spend the summer in Heidelberg at the fabled Ruprecht-Karls-Universität and the German Cancer Research Institute.

Jen will work in a collaborate project on shared open source infrastructure for radiation therapy research ( Heidelberg is doubtless one of the most spectacular places in Europe, so I suppose Jen will have a constant stream of visitors :-)


Multidimensional data (2D+t, 3D+t) support added to 3D Slicer

Replay of ultrasound-guided needle insertion procedure in 3D Slicer

We've implemented the MultidimData extension for 3D Slicer that allows creating, editing, and browsing sequences of nodes, such as 4D volumes, 3D models changing in time, sequence of tracked ultrasound frames and tool navigation data, etc. The MultidimData extension is available for the Slicer nightly builds. See more information on the MultidimData module's documentation page.
