Webinar on Fundamentals of PET
Brief summary of contents

Within a few minutes and 15 slides, these four elements are discussed.
  • PET imaging is a widely established procedure in nuclear medicine starting al-ready in 1970s 
  • In contrast to earlier methods utilizing radioisotopes emitting “only” a single photon, it uses positron emitting isotopes which in turn annihilate with an elec-tron and produce simultaneously two high energy photons with 511keV
  • The detection of those photons require a sophisticated approach utilizing a so-called electronic collimation
  • With the integration of PET and CT scanners into a single device around the year 2000, PET/CT became a major player in the field of molecular imaging

Webinar on the Fundamentals of CT
Brief summary of contents

The slides cover the history of diagnostic imaging with x-ray and computed tomography systems. While there is a large joined history between the two modalities, we review the hands-on difference between the two x-ray based methods. We look closer at the top four parts of a CT scanner, namely an x-ray tube, detector, gantry and reconstruction engine. Further we shortly discuss the differences solutions / algorithms for solving the inverse problem, e.g., analytical versus iterative reconstruction. Finally we discuss the Hounsfield units and its meaning for CT imaging.
