  1. 1. Non-invasive imaging for improved cardiovascular diagnostics Shear wave elastography, relative pressure estimation, and tomographic reconstruction

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : David Marlevi; KTH.; Karolinska Institutet.; Karolinska Institutet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknologi; Medical Technology; Medical imaging; Cardiovascular disease; Atherosclerosis; Hemodynamics; Ultrasound; Shear Wave Elastography SWE ; Magnetic Resonance Imaging MRI ; 4D flow MRI; Relative Pressure; Virtual Work-Energy; micro-Computed Tomography micro-CT ; Tomographic reconstruction; Pre-clinical imaging; Medicinsk avbildning; Hjärt-kärlsjukdomar; Ateroskleros; Hemodynamik; Ultraljud; Skjuvvågselastografi SWE ; Magnetresonanstomografi MRI ; 4D flödes-MRI; Tryckfall; Virtuellt flöde; mikro-Datortomografi mikro-CT ; Tomografisk rekonstruktion; Preklinisk avbildning;

    Abstract : Medicinsk avbildning utgör idag en central del av modern klinisk diagnostik, och bildgivande diagnostikverktyg har kommit att i grunden förändra sättet på vilket dagligt kliniskt arbete utförs. Medicinsk bildteknik används också i stor utsträckning inom hjärt-kärldiagnostik, och i takt med att nya tekniker utvecklas kan förfinad information inhämtas: ultraljudsbaserad elastografi möjliggör avbildning av vävnaders mekaniska egenskaper, fyrdimensionella blodflödesmönster kan kartläggas genom 4D flödes-magnetresonanstomografi (MRI), och mikro-Datortomografi (mikro-CT) möjliggör preklinisk avbildning i mikrometerupplösning.

  2. 2. Definition of axonal injury tolerances across scales A computational multiscale approach

    University dissertation from Kungliga Tekniska högskolan

    Author : Annaclaudia Montanino; KTH.; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic Brain Injury; Axonal Injury; Mechanoporation; Multiscale;

    Abstract : Traumatic brain injury (TBI) is today regarded as a global health challenge. Revealing how external mechanical loads translate into tissue and cellular damage is necessary, not only for the development of better preventive measures, but also for the definition of treatments that could spare the patients from suffering TBI's devastating consequences.

  3. 3. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating

    University dissertation from KTH Royal Institute of Technology

    Author : Qingling Xia; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural modulation; infrared laser; in - vitro experiment; multi - electrode arrays MEA ; heating model; temperature; neural networks; infrared neural inhibition INI ; hyperexcitation;

    Abstract : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

  4. 4. Evaluation of Fluid-Structure Interaction and Biofidelity of Finite Element Head Models

    University dissertation from KTH Royal Institute of Technology

    Author : Zhou Zhou; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied Medical Technology; Tillämpad medicinsk teknik;

    Abstract : Traumatic brain injury is a critical public health issue. Finite element (FE) head models are valuable instruments to explore the causal pathway from mechanical insult to resultant brain injury. Intracranial fluid-structure interaction (FSI) and biofidelity evaluation are two fundamental aspects of FE head modeling. READ MORE

  5. 5. Combining the tactile resonance method and Raman spectroscopy for tissue characterization towards prostate cancer detection

    University dissertation from Luleå : Luleå tekniska universitet
