Better planning to reduce risk in liver surgeries
Patients who have liver cancer and are eligible for surgery, have until recently had to go through a formal liver resection where the surgeons remove the infected half of the liver. Such a procedure reduces the possibility to have another surgery if cancer reoccurs.
The alternative is to perform a parenchymal-sparring resection meaning that the surgeons remove a smaller portion of the liver near the lesion itself. Planning of the parenchymal-sparring resection is difficult because the surgeons have to rely on two-dimensional CT or MR images that do not give an accurate visualisation of where a tumour is placed.
Therefore the surgeons need to use their experience and imagination to create each their own perception of the anatomy of the patient's liver and agree on the course of action.
The project has resulted in a solution that visualises the liver in 3D and where the surgeons can interact with the model to better plan the laparoscopic liver surgery. Through detection and tracking of the surgical tools, the application can be used intraoperatively and provide navigational assistance during laparoscopic surgery so that the surgeons don't have to rely on their individual perceptions of the patient's liver.
