Phil Smith will be discussing the tracking of surgical instruments for dexterity assessment with particle filters as his presentation for his MPhil-PhD transfer.
The style of medical training has emphasized more on standardized and objective assessment of clinical, academic and surgical knowledge. Traditionally in ophthalmology surgical skills are often assessed in the operating theatre environment with the supervising surgeon directly observing or providing feedback whilst watching a recording of the operation. This can be of great subjective variability and is not readily reproducible. Certain components of surgical skills can be determined by analyzing the movement of the instruments.
We propose a method based upon object tracking to analyse the movement of surgical instruments. Through various approaches the viability of object tracking for this novel application is explored. Further to this we describe an approach that is able to track surgical instruments in cataract surgery using particle filters based on motion and colour cues. The experiments have shown it is possible to track various instruments even though prior information regarding their appearance is limited or unknown.
