Laparoscope Self-calibration for Robotic Assisted Minimally Invasive Surgery

For robotic assisted minimal access surgery, recovering 3D soft tissue deformation is important for intra-operative surgical guidance, motion compensation, and prescribing active constraints. We propose in this paper a method for determining varying focal lengths of stereo laparoscope cameras during robotic surgery. Laparoscopic images typically feature dynamic scenes of soft-tissue deformation...

Robotic-assisted minimally invasive surgery and ovarian cancer

Ovarian cancer is the fifth most common cancer in women, and the most lethal gynecologic malignancy in western countries. Approximately 70% of malignant ovarian cancers are diagnosed with diffuse intraperitoneal spread. The treatment algorithm for ovarian cancer consists of the combination of maximal cytoreductive surgery and chemotherapy [1]. Advanced stages, requiring major tumor debulk ing, ...

Stereoscopic Scene Flow for Robotic Assisted Minimally Invasive Surgery

Information about the 3D shape and motion of tissue surfaces at the surgical site during minimally invasive surgery is important for providing metric measurements that enable the deployment of image-guidance and enhanced robotic control. This article presents a scene flow algorithm that recovers the deformation and 3D structure of the surgical field-of-view from stereoscopic images by propagati...
