Acquisition and Processing for Cardiovascular PET (Slides)

Pdf Summary

This document is part of a module on Acquisition and Processing for Cardiovascular PET in the Instrumentation section. It discusses various components and techniques used in cardiovascular PET imaging.<br /><br />The document covers the following topics:<br />- Components of PET scanners and their functions<br />- Differences between dedicated and hybrid imaging systems<br />- Quality control requirements for high-quality PET imaging<br />- PET acquisition techniques such as 2D vs 3D, frame mode, list mode, point spread function, and time of flight<br />- PET reconstruction setup, including ECG gating, respiratory gating, and motion compensation<br />- Attenuation correction and its impact on imaging<br />- Calculation of myocardial blood flow and its impact on patient motion<br />- The use of CT for attenuation correction and its alignment with PET images<br />- Motion correction techniques for improved image quality<br />- Extraction of input functions and time-activity curves for myocardial blood flow estimation<br />- The roll-off effect of common myocardial PET tracers<br />- Myocardial flow reserve calculations<br /><br />The document highlights that 3D-PET with CT is the primary modality for cardiac imaging and that resolution recovery, time-of-flight, and motion correction techniques improve image quality. It also mentions that several quantitative flow packages have been developed, but motion during dynamic scanning and PET/CT misregistration remain important technical challenges.<br /><br />Overall, the document provides an overview of the instrumentation and techniques used in cardiovascular PET imaging, focusing on acquisition and processing methods.
