Computer-Aided Surgery and Therapy
CA enables us to understand the anatomy of each individual surgery patient. Such understanding can be achieved by detailed segmentation of preoperative CT images, to provide organ shape information that can be used for preoperative simulations such as for procedures such as laparoscopic surgery. In the following subsections, we will show several examples of preoperative simulations based on the CA model.
Laparoscopic Surgery Simulation
The main goal of laparoscopic surgery simulation is classified into the following categories: (a) surgical training, (b) surgical rehearsal, and (c) surgical procedure planning. In surgical training, the simulator can train novice surgeons. The main purpose of this system is to impart basic laparoscopic surgery skills such as suturing or membrane peeling. Because this involves learning to manipulate an endoscope or a forceps, detailed representation of patient anatomy is not necessary. Basic representation of an organ shape is sufficient for this kind of simulation. In surgical rehearsal, a great deal of the anatomical information of a specific patient is required. This information can be obtained by processing multi-organ CT segmentation data using surface rendering or volume rendering. Endoscope- or forceps-like user interface devices are used to achieve more realistic reference image generation.
Surgical planning and rehearsal include patient-specific anatomical information and organ deformation simulations using individual patients’ organ morphology. CA is crucial to accurate depiction of patient-specific organ morphology.
