Siemens Reconstructs PET in High Definition

June 5, 2007 - Siemens introduced at SNM its HD PET, a technology which is designed to deliver superior detection of small lesions, dramatically greater staging capabilities and therapy accuracy.
True V extended field of view (FOV) technology in HD PET reportedly improves 2 mm resolution enables to clearly visualize the smallest of lesions from the center to the edges. It provides twice the signal-to-noise improvement and near uniform spatial resolution throughout the field-of-view. HD PET incorporates millions of point spread functions (PSFs) in the reconstruction algorithms. Using measured PSFs, HD PET effectively positions the line of response in their actual geometric location, which dramatically reduces blurring and distortion in the final image.
HD PET specificity and accuracy and will useful for physicians delineating small lesions, including those in lymph nodes, abdomen, head and neck and brain, to provide earlier, more targeted treatment.
