Virtual reality and simulation training improve skill acquisition by allowing trainees the opportunity to deliberately practice procedures in a safe environment. The purpose of this study was to find if there was a difference in the amount of improvement the Perk Tutor, an augmented reality training tool, provided depending on the complexity of the procedure.
METHODS
We conducted two sets of spinal procedure experiments with different levels of complexity with regards to instrument handling and mental reconstruction – the lumbar puncture and the facet joint injection. In both experiments subjects were randomized into two groups, Control or Perk Tutor. They were guided through a tutorial, given practice attempts with or without Perk Tutor, followed by testing without Perk Tutor augmentation.
RESULTS
The Perk Tutor significantly improved trainee outcomes in the facet joint experiment, while the Perk Tutor …},

In prostate brachytherapy, real-time dosimetry would be ideal to allow for rapid evaluation of the implant quality intra-operatively. However, such a mechanism requires an imaging system that is both real-time and which provides, via multiple C-arm fluoroscopy images, clear information describing the three-dimensional position of the seeds deposited within the prostate. Thus, accurate tracking of the C-arm poses proves to be of critical importance to the process.
Methodology
We compute the pose of the C-arm relative to a stationary radiographic fiducial of known geometry by employing a hybrid registration framework.
