  1. 21. Artifacts handling and DBS electrodes localization in the CT/MRI brain images

    University essay from Institutionen för informationsteknologi

    Author : Amir Motevakel; [2013]
    Keywords : ;

    Abstract : In the DBS surgical treatment  the location of the electrodes has direct influence on the success rate of treatment.  Considering the fact that MRI imaging is not compatible with metal, post-operative CT images should be used to locate the electrodes on pre-operative MRI images which contain information about soft tissues.

  3. 22. Prototype Development of an A-Mode Ultrasound Based Intrafraction Motion Management System

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Abebe Hailu; Fredrik Lundqvist; [2013]
    Keywords : Intrafraction motion management; A-mode ultrasound; stereotactic body radiation therapy; ultrasonic distance measurement; embedded system;

    Abstract : Owing to the steep dose fall-off curves of high precision and accuracy radiation therapy (RT) modalities such as stereotactic body RT (SBRT), treatment plans with extraordinarily small margins to organs at risk (OARs), such as the spinal cord, has been made possible. With this development, patient movements during treatment, i.e. READ MORE

  4. 23. Accuracy of inverse treatment planning on computed tomography like images derived from magnetic resonance data

    University essay from Institutionen för fysik

    Author : Mohammad Mehdi Akhtari; [2013]
    Keywords : ;

    Abstract : Treatment planning for radiotherapy involves different types of imaging to delineate target volume precisely. The most suitable sources to get 3D information of the patient are the computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT modalities. READ MORE

  5. 24. Impact of PET in the Radiation Therapy Planning for Pediatric Cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Josefine Ståhl Kornerup; [2012]
    Keywords : Medicine and Health Sciences;

    Abstract : I Sverige drabbas omkring 300 barn av cancer varje år och majoriteten av dem är bara fyra-fem år gamla när de får sin diagnos. Omkring två tredjedelar av barncancerdiagnoserna utgörs av leukemier, lymfom och hjärntumörer, medan den sista tredjedelen är olika solida tumörformer som njurtumörer och nervvävnadstumörer i buken.

  6. 25. Simulation of radio-frequency ablation of liver tumors : Development of a power regulation model and comparison with microwave ablation

    University essay from Mekanisk värmeteori och strömningslära

    Author : Chiara Sammartano; [2011]
    Keywords : ;

    Abstract : Local therapy with radiofrequency ablation (RFA) is an important method for treating liver tumors mostly in early stage, which has been increasingly used in recent years. RFA utilizes an RF current that is applied to the target tissue through an electrode connected with a power generator and percutaneously inserted into the tumor; the electrode power causes the tissue temperature rise required for destroying cancer cells.
