Deformation estimation of an elastic object by partial observation using a neural network

HE number of diseases that can be treated by surgical operation has increased in recent years because of the development of medical technology. However, the complexity of treatment plans means that surgical navigation under treatment is a potentially valuable development. In surgical navigation, computer simulation of treatment plans is constructed before a surgery, and a virtual internal organ deformed following surgical treatment is presented to the surgeon during the surgery. It helps surgeons to operate as planned and provides an alert to prevent accidents, for example, they hurt important blood vessels. In surgical operations, laparoscopic surgery is considered less trauma for patients than laparotomy, and leads to faster recovery [1]. However, laparoscopic surgery is more difficult for doctors than laparotomy surgery, because it involves restricted vision and limited freedom of surgical instruments, making it difficult to move the instruments in the operating field [2].
