Hybrid Imaging (Slides)

Pdf Summary

This document is part 2 of a module on hybrid imaging, specifically PET/CT imaging. The author discusses the benefits and uses of hybrid imaging, including attenuation correction, assessment of coronary calcium, and evaluation of anatomical structures. The author also explains the production of x-rays in CT imaging and the settings of the x-ray tube. The difference between single-detector and multi-detector CT scanners is also explained. The author emphasizes the importance of motion correction in cardiac PET/CT imaging and discusses challenges in CT attenuation correction, such as x-ray energy range and metallic objects. The use of CT for attenuation correction in PET imaging is explained, as well as the effects of motion on image quality and the importance of misregistration correction. The document also covers the importance of quality control and dosimetry in CT imaging. Finally, the author highlights the need for radiation protection strategies in CT imaging due to the high intensity and low energy of the x-ray beam. The document provides a comprehensive overview of hybrid imaging and the role of instrumentation in PET/CT imaging.
