  1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    University essay from Lunds universitet/Fysiska institutionen

    Author : Klara Stefansson; [2024]
    Keywords : Technology and Engineering;

    Abstract : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. READ MORE

  3. 2. 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

  6. 5. Reduction of Acrylamide in Reject Water from Sludge Dewatering

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martina Aspegren; [2023]
    Keywords : Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Abstract : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. READ MORE
