Design outcomes

Primary

Measure	Time frame
The primary outcome is the investigation of the hypothesis that multispectral imaging can be used to detect ischemia in the kidney. The evaluation takes place outside the OR after the surgery has finished. The multispectral images are post-processed with Machine Learning and Deep Learning algorithms to predict the perfusion state (perfused or non-perfused) of the kidney. This prediction is compared to the ground truth state available because of the placement of a clamp severing the kidney from the main blood supply during surgery	—
