  1. 41. Needle Navigation for Image Guided Brachytherapy of Gynecologic Cancer

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

    Author : Alireza Mehrtash; [2019]
    Keywords : Image Guided Surgery; Surgical Navigation System; Needle Navigation system; Brachytherapy; MRI; 3D Slicer;

    Abstract : In the past twenty years, the combination of the advances in medical imaging technologies and therapeutic methods had a great impact in developing minimally invasive interventional procedures. Although the use of medical imaging for the surgery and therapy guidance dates back to the early days of x-ray discovery, there is an increasing evidence in using the new imaging modalities such as computed tomography (CT), magnetic reso- nance imaging (MRI) and ultrasound in the operating rooms.

  3. 42. Machine learning multicriteria optimization in radiation therapy treatment planning

    University essay from KTH/Matematisk statistik

    Author : Tianfang Zhang; [2019]
    Keywords : Radiation therapy; automated planning; machine learning; multicriteria optimization; dose mimicking; dose--volume criteria; Gaussian mixture model; expectation--maximization; exponential tilting; Strålterapi; automatisk planering; maskininlärning; flermålsoptimering; dosåterskapande; dos--volym-kriterier; gaussisk blandningsmodell; förväntning--maximering; exponentiell lutning;

    Abstract : In radiation therapy treatment planning, recent works have used machine learning based on historically delivered plans to automate the process of producing clinically acceptable plans. Compared to traditional approaches such as repeated weighted-sum optimization or multicriteria optimization (MCO), automated planning methods have, in general, the benefits of low computational times and minimal user interaction, but on the other hand lack the flexibility associated with general-purpose frameworks such as MCO.

  5. 44. Usability evaluation of a visualization system for urologists

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

    Author : Mai-Khanh Lê; [2019]
    Keywords : Visualization; interactive; prostate cancer research; usability; evaluation;

    Abstract : Urologists, researchers and statisticians work with a centralized database in Stockholm containing more than two million prostate cancer patient records. In order to expedite the analytical process, an interactive visualization system was developed through the collaboration of Janssen and KTH. READ MORE

  6. 45. Towards unification of organ labeling in radiation therapy using a machine learning approach based on 3D geometries

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

    Author : Giorgio Ruffa; [2019]
    Keywords : ;

    Abstract : In radiation therapy, it is important to control the radiation dose absorbed by Organs at Risk (OARs). The OARs are represented as 3D volumes delineated by medical experts, typically using computed tomography images of the patient. READ MORE
