Goal
The goal of this study is to determine the usability and accuracy of holographic surgery in children with kidney tumors.
Background
In some children with a kidney tumor, the surgeon needs to remove the tumor and spare the kidney. To help the surgeon, we have developed a holographic surgery technique. This technique allows the surgeon to see inside the kidney to find the tumor, hopefully making it easier to remove the tumor completely.
We first need to study the accuracy and usability of the technique. Therefore, in this study we measure how well we position a hologram on the kidney during an operation.
First we create a 3D model with the MRI images made before the operation and show it to the surgeon as a hologram. The surgeon uses special holographic glasses (HoloLens) to look at the hologram. During the actual surgery, the surgeon places the hologram onto the kidney. When the surgeon is comfortable and satisfied with the position, we measure the accuracy. The surgeon removes the glasses after a maximum of ten minutes, and continues with the operation as normal.
We will use the holographic glasses while the patient is asleep for surgery, and this will take a maximum of ten minutes. Otherwise, the operation proceeds like any other normal operation in which the kidney is removed. The patients therefore do not notice this themselves.
