  1. 1. Investigation of a Collapsed Cone Superposition Algorithm for dosimetry in brachytherapy

    University essay from Stockholms universitet/Fysikum

    Author : Freja Alpsten; [2021]
    Keywords : Brachytherapy; Collapsed Cone; Model-Based Dose Calculation Algorithms; Radiotherapy;

    Abstract : Background & Purpose: The current standard dosimetry in brachytherapy treatment planning, the TG-43 formalism, ignore the presence of non-water media and finite patient dimensions. This can cause clinically relevant errors in dose estimates. READ MORE

  3. 2. Three material decomposition in dual energy CT for brachytherapy using the iterative image reconstruction algorithm DIRA : Performance of the method for an anthropomorphic phantom

    University essay from Institutionen för medicinsk teknik; Tekniska högskolan

    Author : Robin Westin; [2013]
    Keywords : DECT; Iterative reconstruction; Tissue decomposition; Numerical stability; Uncertainty propagation;

    Abstract : Brachytherapy is radiation therapy performed by placing a radiation source near or inside a tumor. Difference between the current water-based brachytherapy dose formalism (TG-43) and new model based dose calculation algorithms (MBSCAs) can differ by more than a factor of 10 in the calculated doses.
