Dealing with Soft Tissue Deformation in Liver Surgery

The augmentation of soft tissue with internal structures derived from imaging and planning data, in particular dealing with the deformation of this tissue, seems to be a quite hot topic at the moment. I have reported on the ISMAR publication of Nazim Haouchine, recently. Another video and publication has attracted my attention, which is about an augmented reality system for laparoscopic liver surgery to support planning procedures and instrument guidance tasks.

The solution described in the work presented at MICCAI 2014 „co-registers pre-operative CT with stereo laparoscopic images using cone beam CT and fluoroscopy as bridging modalities. It does not require fiducials or manual alignment and compensates for tissue deformation from insufflation and respiration while allowing the laparoscope to be navigated.
