Real-Time Mosaicing of Fetoscopic Images


The video shows an example of the mosaicing methods our researchers are developing as part of the first-year milestones in WorkPackage 1.

When surgeons currently perform fetal surgery on mothers with twins suffering from Twin-to-Twin Transfusion Syndrome they must cauterize the connected vessels on the placenta using a fetoscope and a laser.

The current fetoscopes offer the surgeon a very limited field of view. This is represented by the view on the left-hand of the video.

The mosaicing method stitches together the real time images collected using the fetoscope giving the surgeon a fixed view of the placenta, which is represented by the image on the right hand side of the video. This will compliment the real-time view from the fetoscope to improve the planning and accuracy of the operation.
