  1. 1. Synthesizing of brain MRE wave data

    University essay from KTH/Medicinsk avbildning

    Author : Maryia Yuliuhina; [2023]
    Keywords : MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

    Abstract : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. READ MORE

  3. 2. A viscoelastic evaluation of an injectable disulfide cross-linked thiol-collagen hydrogel: for tissue bulking post-myocardial infarction to prevent heart failure

    University essay from Uppsala universitet/Makromolekylär kemi

    Author : Karin Dungner; [2023]
    Keywords : ;

    Abstract : Cardiovascular diseases are currently the leading cause of death globally. Progression of the disease affects the composition and function of the heart and in many cases subsequently results in heart failure over time where a heart transplant is vital. Therefore, there is a need for medical treatments to stop the progression of the disease. READ MORE

  4. 3. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry

    University essay from KTH/Fiber- och polymerteknologi

    Author : Murtaza Sharq; [2022]
    Keywords : Injectable and shape-retaining collagen hydrogel; crosslinked using bio-orthogonal cycloaddition chemistry; Injicerbara och formbevarande kollagenhydrogeler; tvärbundna med bio-ortagonal cykloadditionskemi;

    Abstract : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. READ MORE

  5. 4. Assessing the Extent of Diffuse Liver Disease: Quality Assurance of Magnetic Resonance Elastography (MRE)

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anna Åkvist; [2022]
    Keywords : ;

    Abstract : The mechanical properties of liver tissue such as stiffness are closely correlated with various diseases. Magnetic resonance elastography (MRE) aims at estimating these mechanical properties by imaging the waves induced by an external driver in the liver. READ MORE

  6. 5. Improvement of the substrate layer in a photovoltaic system for neural implants

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

    Author : Justina Venckute Larsson; [2022]
    Keywords : Bioengineering; Photovoltaic; substrate; neural implant; Parylene C; Bioteknik; solceller; substrat; neurala implantat; Parylen C;

    Abstract : Neural implants have been developed to aid with different neurological disorders. Although there are neural implants that are used to treat patients today, there is still room for improvement in the field. READ MORE
