1. 1. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Thi Guldhill; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE

3. 2. 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

4. 3. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

   University essay from

   Author : Christian Waldenberg; [2022-11-08]
   Keywords : Medical physics; Normoxic polymer gel dosimeter; NiPAM;

   Abstract : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. READ MORE

5. 4. Hyaluronic Acid Hydrogel as a Scaffold for Cells’ Encapsulation

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Susanna Wärmegård; [2022]
   Keywords : hyaluronic acid; hydrogel; 3D cell culture;

   Abstract : Hydrogels are high water-content polymers that mimic the extracellular matrix of cells. The polymers can have many sources and be of natural origin from the extracellular matrix (ECM) of cells or be synthetically derived. READ MORE

6. 5. Polymer gel dosimetry - Using MRI-readout, simplified relatively non-toxic mixing procedure tested on FLASH

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Maria Blomstedt; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to its favorable qualities such as very high resolution, 3D coverage, tissue equivalence and independence of energy and incident direction of the radiation beam.
