This webinar will be a guided tour to PET image reconstruction for the application-oriented user making sense of the sometimes complex reconstruction concepts. The webinar will cover the Pros & Cons and FAQs of PET image reconstruction, from analytical (FBP) to iterative methods (MLEM, OSEM and MAP), from the importance of physical corrections (scatter, attenuation etc) to reconstruction acceleration and noise reduction. In addition, the webinar will give you a glimpse of what to expect in the future with exciting insights into topics like how MRI can make better PET images and how AI can be applied to PET reconstruction.
During the first part of the webinar Dr. Josep Oliver will provide an overview all the basic concepts of PET image reconstruction. Josep will cover iterative and analytical algorithms discussing their fundamentals, as well as, their advantages and disadvantages and recommended settings. Key concepts like resolution, noise, artifacts and convergence will be explained in a manner that allows the application-oriented user to understand the impact of reconstruction parameters on quantification and image quality. In the second part, Dr Harry Tsoumpas will discuss the importance of data corrections as part of image reconstruction and then will proceed with an outlook to exciting new PET image reconstruction opportunities arising from the availability of hybrid imaging devices combined with current trends in computer science. Josep and Harry will be available at the end to take questions from the audience.
