Augmented Reality Guided Tumour Resection
In this video we show how our custom neuronavigation system can be used with an external camera to created an augmented reality view to assist with tumour resections when anatomy of interest isn't directly visible in the surgical field

Intraoperative Ultrasound Imaging
Ultrasound is a noninvasive form of imaging that can be used to update preoperative MRI images during neurosurgery to improve neuronavigation accuracy. For the ultrasound images to be useful, the transducing probe must be tracked in order to relate the location of the MRI slices. In the images below the greyscale image represents the MRI and the orange is the ultrasound. The MRI is being rotated and translated to match the intensity of the ultrasound images. This is an example of a rigid transformation.
As surgery progresses, rigid transformations are not always suitable to accurately account for the changes that have occurred. We must then rely on nonlinear transformations.
