  1. 11. Overcoming generative likelihood bias for voxel-based out-of-distribution detection

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

    Author : Einar Lennelöv; [2021]
    Keywords : Variational autoencoder; out-of-distribution detection; likelihood bias; voxel representation; radiation therapy; Variationell autokodare; anomalidetektion; sannolikhetssnedvridning; voxelrepresentation; strålbehandling;

    Abstract : Deep learning-based dose prediction is a promising approach to automated radiotherapy planning but carries with it the risk of failing silently when the inputs are highly abnormal compared to the training data. One way to address this issue is to develop a dedicated outlier detector capable of detecting anomalous patient geometries. READ MORE

  3. 12. EPID image prediction using a U-net model.

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

    Author : Felix Liu; [2020]
    Keywords : ;

    Abstract : Radiation therapy is one of the most common treatment methods for cancer today, with an estimated half of patients requiring it at some point in the course of their illness. In radiation therapy, verification of treatment plans is an important process. READ MORE

  4. 13. Analysis of bladder cancer treatment plans generated for online adaptive radiotherapy and validation of an integrated independent dose calculation software

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Daria Badika; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: In 2019 Varian EthosTM linear accelerator (Varian Medical Systems, CA, USA) with integrated artificial intelligence (AI) was installed at Herlev Hospital, Copenhagen, Denmark, enabling online adaptive radiotherapy (oART) e.g for bladder cancer patients with a large margin reduction.

  5. 14. Deep Learning Based Multi-Label Classification of Radiotherapy Target Volumes for Prostate Cancer

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Lina Welander; [2019]
    Keywords : Multi-label classification; MIQA; INCA; Deep neural network;

    Abstract : An initiative to standardize the nomenclature in Sweden started in 2016 along with the creation of the local database Medical Information Quality Archive (MIQA) and a national radiotherapy register on Information Network for CAncercare (INCA). A problem of identifying the clinical tumor volume (CTV) structures and prescribed dose arose when the consecutive number, which is added to the CTV-name, was made inconsistently in MIQA and INCA.

  6. 15. New potential treatment protocol for radiotherapy of glioblastoma

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Victor Pham; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Purpose: Improvements in mortality rate of glioblastoma patients have been limited during the past decades, due to the tumor’s rapidly growing and infiltrative behavior and resistance to current therapy. Recent findings show that higher brain mean dose strongly correlates with inferior overall survival and that local recurrences mainly occur centrally in previously irradiated regions. READ MORE
