Less Exposure to Radiation During CT Perfusion Examinations

So-called perfusion examinations using a computer tomograph are very helpful for quickly making an accurate diagnosis following a stroke. However, they expose the patient to radiation. Dr. Rainer Raupach, who works on the development of new medical technology systems at the Siemens plant in Forchheim, has discovered a new method of image processing that reduces the radiation exposure by up to 75 percent while still providing the same amount of information.
