  1. 16. Deep Learning with Importance Sampling for Brain Tumor MR Segmentation

    University essay from KTH/Optimeringslära och systemteori

    Author : Hanna Westermark; [2021]
    Keywords : Deep learning; importance sampling; segmentation; convolutional neural networks; MRI; brain tumour; Djupinlärning; importance sampling; segmentering; faltningsnätverk; MRI; hjärntumör;

    Abstract : Segmentation of magnetic resonance images is an important part of planning radiotherapy treat-ments for patients with brain tumours but due to the number of images contained within a scan and the level of detail required, manual segmentation is a time consuming task. Convolutional neural networks have been proposed as tools for automated segmentation and shown promising results. READ MORE

  3. 17. Reinforcement learning applied to MLC tracking

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Adithya Raju Ganeshan; [2021]
    Keywords : Reinforcement Learning; Multileaf Collimator; Magnetic Resonance Imaging; Adaptive Radiotherapy;

    Abstract : Radiotherapy has become an ever more successful treatment option for cancer.Advances in imaging protocols combined with precise therapy devices suchas linear accelerators contribute towards millimeter precision of treatmentdelivery with far fewer side effects. READ MORE

  4. 18. Production and Evaluation of a Bombesin Analogue Conjugated to the Albumin-Binding Domain and DOTA for Prostate Cancer Radiotherapy

    University essay from KTH/Proteinvetenskap

    Author : Fredrika Landmark; [2021]
    Keywords : bombesin; prostate cancer; radiotherapy; human serum albumin; half-life extension; bombesin; prostatacancer; radioterapi; humant serumalbumin; halveringstidsförlängning;

    Abstract : Prostate cancer is one of the most common types of cancer worldwide and claims hundreds of thousands of lives annually. Currently the most common treatment for prostate cancer is external beam radiotherapy, however, this treatment comes with serious side effects since it lacks selectivity for the cancer cells.

  5. 19. Toxicity of Pulsed Beams in Radiation Therapy from a Physio-Chemical Perspective

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Karin Källén; [2021]
    Keywords : FLASH; radiotherapy; ultra high; dose rates; radiolysis; cancer; medical; FLASH; strålbehandling; ultrahög; doshastighet; radiolys; cancer; medicinsk;

    Abstract : A significant portion of cancer patients receive radiotherapy as part of their curative or palliative treatment plan. Radiotherapy is however greatly limited by radiation induced toxicities in healthy tissue surrounding the tumour, which can lead to long-term or acute complications for a patient. READ MORE

  6. 20. 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
