Comparison of PSF and Non PSF BLOB based reconstructed image in Time-of-Flight PET/CT

Hybrid PET/CT imaging with the use of 18F FDG is a widely used technique major indications in oncology for staging, re-staging and monitoring response to therapy. There issue partial volume effect PET images which affects image quality as well quantitative accuracy small lesions. Multiple attempts have been made resolve these issues. The aim our study was look into impact Point‐spread-function (PSF) on reconstructed attenuation corrected (AC) find out best combination number PSF iterations regularization level while applying PSF.
