Medical Imaging


To realize this vision, Siemens researchers are developing techniques


to promote extremely fast


visualization. For instance, a team led by Dr. Andreas Hutter at Siemens Corporate Technology is focusing on ways to tailor


streaming and video compression to


medical applications, while others are working with chip manufacturers to minimize the computing and power demands needed to process images. “These efforts are starting to pay off,” says Yu. “They have made it possible for us to stream real-time images to a tablet using standard Ethernet technology.”


The need to achieve a virtually imperceptible delay is clear. “If you are pushing a needle or a catheter through a patient's anatomy, you need to have instant feedback,” says Yu. “For instance, if you are doing a procedure in which angiography is involved, our scanner works super-fast to produce each image and encode it. The images must then be streamed to the viewing device, decoded and rendered.” Naturally, processing demands are even higher as additional imaging modalities are added and fused. Nevertheless, whatever delay this adds will probably not be noticeable. With eSieFusion imaging, for instance, initial registration of CT and ultrasound images requires three seconds, after which any two images can be fused in real-time.


“For instance, if you are doing a procedure in which angiography is involved, our scanner works super-fast to produce each image and encode it. The images must then be streamed to the viewing device, decoded and rendered.”
