Speedy 3-D X-rays in the operating room
Date:10/27/2011

This press release is available in German.

Fraunhofer researchers are now developing a 3D X-ray system that can be integrated seamlessly into operating procedure with no more forced interruptions. To find out how this system works, visit the Medica 2011 trade fair in Dsseldorf from November 16 to 19 (Hall 10, Booth F05).

Mrs. S. is more than a little anxious: she is due to be given a spinal implant in three days' time. The elderly lady is worried about complications and not without reason, since complicated operational procedures such as those on the spine, the head or the ankle are a challenge even for highly experienced surgeons. In order to reduce the risk of complications in more difficult operations and to avoid the need for follow-up surgery, doctors carry out progress checks with the help of three-dimensional X-ray images while the operation is in progress. These 3D images allow them to check on the position of implants and fracture fragments, so as to determine the relative positions of pieces of bone or to position implants with millimeter accuracy. The trouble is, currently available 3D X-ray systems such as C-arms interfere with the surgeon's work. The X-ray source and detector have to move in circles around the patient, which takes up a lot of space; if the C-arm were installed on the operating table permanently, it would impede access to patients. So the device must be wheeled over to the operating table to capture the images and then moved out of the way again. This is a nuisance and it takes up time, as it entails an interruption to the surgery.

Researchers at the Fraunhofer Institute for Production Systems and Design Technology IPK are currently working on a solution to this problem. Together with the Charit Universittsmedizin Berlin university hospital and Ziehm Imaging GmbH, they are developing ORBIT, a 3D X-ray scanne
