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. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

   University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

   Author : Lovisa Byström; [2023]
   Keywords : Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

   Abstract : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. READ MORE

4. 3. Anisotropic Muscle Phantoms for Shear Wave Elastography Assessment of the Levator Ani Muscle Properties

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Bleona Koxha; Melissa Jova Martinez; [2023]
   Keywords : pelvic floor disorder; levator ani muscle; shear wave elastography; phantom; anisotropy; polyvinyl alcohol; bäckenbottenbesvär; levator ani muskel; shear wave elastografi; fantom; anisotropi; polyvinylalkohol;

   Abstract : Pelvic floor disorder is an emerging research area and is highlighted in many pelvic floor studies. Assessment methods for this type of injury are lacking and new methods for prevention and diagnosis are needed. Pelvic floor disorders are common among women and can lead to suffering for the patient. 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.
