Wants to make X-rays more accessible and reliable

Seppo Koskinen, professor of imaging and functional medicine, is involved in the development of methods and new technologies to make radiology even more reliable and at the same time more accessible. Mobile tomography for less mobile patients and better image quality close to metallic implants are two of his recent achievements.

Seppo Koskinen is a clinical radiologist and is researching into how the­ tools and methods of radiology can be improved.

"We want radiology to become a ‘one stop shop’ in health care," he says. "It must often be carried out quickly, but it is important to obtain reliable information - preferably complete information so that the patient does not need to come back for new images."

In one of his current projects, he has been involved in the development of new methods ­for reducing the noise in X-ray images that metallic implants often cause. By combining modern technology with specially developed software, the group has succeeded in filtering out much of the interference - which gives doctors better chances of detecting cancer, for example.

In another collaborative project, Seppo Koskinen has helped a company to develop a mobile tomography unit.

"It is often difficult and sometimes impossible to move a patient from intensive care to the radiology department," he says. Previously it was necessary to use plain X-ray in such cases, but with this unit it is possible to make a CAT scan of an elbow or knee by the patient's bed. The tomograph can also be used when a patient is standing, which is a great advantage for symptoms that only occur under load, as in an ankle.

Seppo Koskinen is now looking forward to teaching more in his new role as professor at KI.

"For me, it is an important and enjoyable part of the job, and the border between education and research is not sharp. Something that I am very interested in is developing the use of our digital image archives for both teaching and research purposes."
