2016_Imaging for Physicists

Summary / Conclusion

 For quantitative PET imaging, raw data correction is necessary ● Random, scatter and dead time correction ● Normalization ● Attenuation correction with CT!  Image reconstruction ● FBP, ML-EM, OSEM, 3D-reconstruction protocols

 Automatic contouring algorithms for RT ● Absolute / relative thresholding

● Iterative thresholding ● Source-to-background ● Gradient-based algorithm
