1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Ibtisam Dahir Ahmed; [2023]
   Nyckelord :Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

   Sammanfattning : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. LÄS MER

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

   Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

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

   Sammanfattning : 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. LÄS MER

4. 3. Ultrasound Imaging Velocimetry using Polyvinyl Alcohol Shelled Microbubbles

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Ida Johansson; [2022]
   Nyckelord :Ultrasound imaging velocimetry; ultrasound contrast agents; polyvinyl alcohol; microbubbles; echo particle image velocimetry; Ultrasound imaging velocimetry; ultraljudskontrastmedel; polyvinylalkohol; mikrobubblor; echo particle image velocimetry;

   Sammanfattning : Current research within the field of ultrasound contrast agents (UCAs) aims at developing capsules which are not only acoustically active, but also have a chemically modifiable surface. This enables use in new areas, including targeted drug delivery and theranostics. LÄS MER

5. 4. Utveckling av ultraljudsbaserad skjuvvågselastografi för hälsenan

   Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

   Författare :Anton Johansson; Daniel Jacobsson; [2022]
   Nyckelord :Shear wave elastography; Ultrasound; Elastic modulus; Achilles tendon; Skjuvningsvågselastografi; Ultraljud; Elasticitetsmodul; Hälsena;

   Sammanfattning : Genom att generera mer information om hälsenan i form av dess elasticitet kan förhoppningsvis fler slutsater nås gällande diagnostik och behandling. Elastografi med hjälp av ultraljud skulle kunna vara en metod för att bidra med denna information. LÄS MER

7. 5. Development of patient-specific fetal head phantom for experimental evaluation of vacuum assisted delivery

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Maria Pop; [2021]
   Nyckelord :Vacuum assisted delivery; Vacuum extractor device; Traction force; Vacuum pressure; Fetal head phantom; Ultrasound imaging; Sonomicrometry;

   Sammanfattning : Vacuum assisted delivery (VAD) is a common procedure used in the final stage of labor in the situation of a difficult natural delivery. Since the only biomechanical studies concerning the clinical safe traction force were conducted during 70s using simplified models to mimic the fetal head, concerns remain regarding the side effects of this medical intervention when applying high levels of traction forces.
