Head motion during brain PET imaging can significantly degrade the quality of the
reconstructed image, leading to reduced diagnostic value and inaccurate quantitation. A …

Purposes Subject's motion during brain PET scan degrades spatial resolution and
quantification of PET images. To suppress these effects, rigid-body motion correction …

Dear Sir, In the recently published EJNMMI article titled BQuantification, improvement, and
harmonization of small lesion detection with state-of-the-art PET^ by van der Vos, et al.[1] …

Head motion degrades image quality and causes erroneous parameter estimates in tracer
kinetic modeling in brain PET studies. Existing motion correction methods include frame …

98 Objectives: Existing brain PET motion correction (MC) methods include frame-based
image-registration (FIR) and correction using real-time hardware-based motion tracking …

Head motion is difficult to avoid in long PET studies, degrading the image quality and
offsetting the benefit of using a high-resolution scanner. As a potential solution in an …

Subject motion is unavoidable in clinical and research imaging studies. Breathing is the
most important source of motion in whole-body PET and MRI studies, affecting not only …

Purpose: Motion correction in PET has become more important as system resolution has
improved. The purpose of this study was to evaluate the accuracy of event‐by‐event and …

Head motion during brain PET imaging is not uncommon and can negatively affect image
quality. Motion correction techniques typically either use hardware to prospectively measure …

Purpose Data‐driven rigid motion estimation for PET brain imaging is usually performed
using data frames sampled at low temporal resolution to reduce the overall computation time …
