A project commissioned by Oslo University Hospital (Rikshospitalet)


The challenge:

Patients who have liver cancer, and are eligible for surgery, have until recently had to go through a formal liver resection. That involves removing the infected half of the liver, which reduces the possibility to have another surgery if the cancer reoccurs.

Resecting a smaller portion of the liver (Parenchyma sparring resection) has been difficult, as the surgeons have to agree on a procedure using 2D-CT/MR images. This is a challenging scenario, because it means that each surgeon make their own perception of the liver anatomy and performs the surgery based on that.

In addition, the patient may be positioned differently on the operating table than when the surgeons planned the procedure.

The solution:

The project will explore how surgeons can plan in a better way, how to perform a resection of the liver. The main objective will be to develop an application that includes mixed reality navigation to better plan laparoscopic liver surgery. This will enable surgeons to accurately reorient the anatomical view during the operation. This application can also be used to detect and track surgical tools, to provide navigational assistance to surgeons.

Overall goals:

  • Increase patient safety
  • Increase surgical efficiency in terms of time and cost
