  1. 6. Feasibility of single time point dosimetry during 177Lu-PSMA-617 treatments of prostate cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Elias Nilsson; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Standard dosimetry methods for radionuclide therapies re- quire imaging at multiple time points post injection. An alternative method has been presented in the literature that uses previously acquired pharma- cokinetic data to create so-called dose factors. READ MORE

  3. 7. Spatiotemporal PET reconstruction with Learned Registration

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Pierre Meyrat; [2022]
    Keywords : PET; Tomographic reconstruction; Deep Learning; MLEM; PET; Tomografisk rekonstruktion; Deep Learning; MLEM;

    Abstract : Because of the long acquisition time of Positron Emission Tomography scanners, the reconstructed images are blurred by motion. We hereby propose a novel motion-correction maximum-likelihood expectation-maximization algorithm integrating 3D movements between the different gates estimated by a neural network trained on synthetic data with contrast invariance.

  4. 8. Lesion Segmentation in 3D FDG-PET/CT Scans Using Deep Learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Adam Maen; [2022]
    Keywords : ;

    Abstract : Drug development is an expensive, long and complex process for pharmaceutical companies all around the world. One way to make it more reliable is to evaluate the drug at its early stages, so the decision can be made to go forward or move to another drug, which is also a time-consuming and costly task to be done by human experts.

  5. 9. Hypoxic Target Volume Determination in PET/CT Imaging : The Impact of Deformable Image Registration

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

    Author : Viktor Rosenberg; [2022]
    Keywords : Positron emission tomography; image registration; hypoxic tumour volume; dose escalation; tumour control probability;

    Abstract : Using a tailored dose distribution for personalized radiotherapy with the help of positron emission tomography (PET) might give an edge for successful tumour elimination. One of the main determinants for tumour radioresistance in several solid tumours has been investigated as hypoxia, including head and neck cancer (HNC). READ MORE

  6. 10. Visual Transformers for 3D Medical Images Classification: Use-Case Neurodegenerative Disorders

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi
