Healthcare Perspectives The Secrets of CT: Photon-counting
The invention of computed tomography (CT) was a very important milestone that improved diagnostic capabilities in the field of medicine. Though it was already seen as a game-changer and many improvements were made over the years, it was still limited by image quality and radiation dose, among other things, and not all patients could be diagnosed. This necessitated the development of the photon-counting CT that provides additional clinical information at a low radiation dose and for an increasing number of patients.
In this episode, André Hartung, President of Diagnostic Imaging at Siemens Healthineers, is joined by 4 guests: Anders Persson, Professor of Medical Image Science, Senior Radiologist, and Head of the Centre for Medical Image Science and Visualisation at Linköping University in Sweden; Fabian Bamberg, the Chair of the Department of Radiology at the University of Freiburg in Germany; Thomas Flohr, Head of CT Physics at Siemens Healthineers; and Christian Schröter from the Siemens Healthineers’ Crystal Centre.
Listen to this episode to learn about the limitations of traditional CT scanners and how modern scanners have overcome them. You’ll also hear about photon-counting and the impact it has on image quality. Additionally, you’ll find out the role that artificial intelligence can play in sorting and analyzing the large amount of data that modern CT scanners produce.
