Medical Imaging


Imagine driving to an appointment at night without the benefit of streetlights, signs, people who can help, or even a windshield. All you have are two displays to the side of the steering wheel: One shows a street map; the other shows where you are. Wouldn't things be a lot simpler if the images could be combined?


This is similar to the challenges faced by


cardiologists when performing what are known as “interventional” procedures. To help surgeons keep up with the increasing demand, Siemens has devised a solution that will make these procedures simpler, and more efficient and cost effective.


Interventional procedures include the implantation of a stent or valve by means of a remotely controlled catheter. During which, a nearby monitor typically displays a high resolution pre-operative computed tomography (CT) image of the vascular anatomy while a separate X-ray fluoroscopy image produced in the interventional suite itself displays the real-time location of the catheter tip.


“Surgeons are skilled in putting these images together in their minds,” says Daphne Yu, who heads the Image Visualization Lab at Siemens Corporate Technology in Princeton, New Jersey. “But by using advanced visualization, we can put the pictures together for them.” The big picture, however, is much broader than that. The end goal is to have an operating and interventional environment in which all modalities are ergonomically integrated. This includes live endoscopic images, ultrasound, real-time CT, fluoroscopy, and above all, 3-D pre-operative CT or magnetic resonance (MR) image sets. The latter are particularly important because they can provide the navigational landscape into which all other modalities will eventually be integrated.
