1. 1. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches

   University essay from KTH/Fysik

   Author : Nina Lindström Söraas; [2023]
   Keywords : PET CT; Tomographic reconstruction; Respiratory gating techniques; Image registration; Motion correction; PET CT; Tomografisk rekonstruktion; Gating tekniker; Bildregistrering; Rörelsekorrigering;

   Abstract : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. READ MORE

3. 2. Characterization of Center-of-Mass and Rebinning in Positron Emission Tomography with Motion

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Linder Hugo; [2021]
   Keywords : positron emission tomography; center of mass; motion correction;

   Abstract : Medical molecular imaging with positron emission tomography (PET) is sensitive to patient motion since PET scans last several minutes. Despite advancements in PET, such as improved photon-pair time-of-flight (TOF) difference resolution, motion deformations limit image resolution and quantification. READ MORE

4. 3. Evaluation of Data-Driven Gating for 68Ga-ABY-025 PET/CT in Breast Cancer Patients

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alain-Klaus Ncuti Nobera; [2020]
   Keywords : Data-driven gating; Motion Correction; Affibody molecule; ABY-025; Breast Cancer; HER2; PET CT;

   Abstract : Respiratory motion during PET acquisition degrades image quality. It is mainly the area around the thorax and abdomen which is affected. External devices do provide respiratory gating solutions but are time-consuming to set up on patients and may not always be available. READ MORE
