  1. 1. Exposure Monitoring and Dosimetry - Optimizing Radiation Protection in Interventional Cardiology

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Institutionen för strålningsvetenskaper

    Author : Amanda Pettersson; [2023]
    Keywords : Interventional cardiology; Radiation protection; Air kerma measurements; Radiation shielding; Projection angle;

    Abstract : During interventional cardiology (IC), medical staff are exposed to scattered ionizing radiation from the patient, potentially leading to various radiation-induced health effects. Therefore, shielding devices are routinely used to reduce occupational exposure during IC procedures. READ MORE

  3. 2. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

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

    Author : Jens Eilers Bischoff; [2022]
    Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

  4. 3. Monte-Carlo computations of dose distributions for magnetic resonance guided radiotherapy

    University essay from Uppsala universitet/FREIA

    Author : Claes Fälth; [2021]
    Keywords : Radiotherapy; MRgRT;

    Abstract : The goal with radiotherapy is to damage tumour cells with ionizing radiation while minimizing radiation to healthy tissue. In recent years magnetic resonance guided radiotherapy has become increasingly popular. With this technique a magnetic resonance image of the patient anatomy is obtained in connection with the treatment session. READ MORE

  5. 4. 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. 5. Validation of theoretical cost model for Power and Reliability : Case study of a reliable Central Direct Memory Access system

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

    Author : Sonal Shrivastava; [2021]
    Keywords : Single event upsets; Extra-functional properties; System on Chip; Mean Time Between Failure; Power consumption; Enstaka händelse störs; Extra funktionella egenskaper; System på chip; Medeltid mellan misslyckande; Energiförbrukning;

    Abstract : Safety-critical applications employed in automotive, avionics and aerospace domains are placed under strict demands for performance, power efficiency and fault tolerance. Development of system hardware and software satisfying all criteria is challenging and time-consuming. READ MORE
