Stereoscopic Motion Magnification in Minimally-Invasive Robotic Prostatectomy

Abstract

The removal of the prostate is a common treatment option for localized prostate cancer. Robotic prostatectomy uses endoscopic cameras to provide a stereoscopic view of the surgical scene to the surgeon. Often, this surgical scene is difficult to interpret because of variants in anatomy and some critical structures such as the neurovascular bundles alongside the prostate, are affected by variations in size and shape of the prostate. The objective of this article is to develop a real-time stereoscopic video processing framework to improve the perceptibly of the surgical scene, using Eulerian Motion Magnification to exaggerate the subtle pulsatile behavior of the neurovascular bundles. This framework has been validated on both digital phantoms and retrospective analysis of robotic prostatectomy video.
