1. 1. Implementation of Super-Resolution Ultrasound Imaging for in Vitro Experiments

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Kani Yara; [2022]
   Keywords : B-mode; Localization; Microbubbles; Poly-Vinyl-Alcohol; Tracking; Verasonics; B-mode; Localisering; Mikrobubblor; Poly-Vinyl-Alcohol; Spårning; Verasonics;

   Abstract : Ultrasound imaging systems are a safe and affordable imaging modality with the disadvantage of low spatial resolution, especially for assessing smaller vessels. However, with the implementation of super-resolution ultrasound imaging techniques, studies have shown promising results in achieving a resolution below the diffraction limit. READ MORE

3. 2. Creation of a Finite Element Model andSystem Analysis for the Low and HighFrequency Cryogenic Telescopes of theSpace Mission LiteBIRD

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Matias Rittatore Texeira; [2022]
   Keywords : FEM; FEA; mesh model; CMB; IRAP;

   Abstract : The Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection (LiteBIRD) is a Japan Aerospace Exploration Agency (JAXA)-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the early Universe, through the measurement of their imprint onto the polarization of the Cosmic Microwave Background (CMB). It is an international collaboration, with European Union (EU) operations being coordinated by France. READ MORE

4. 3. Image Contrast Enhancement using Poly Vinyl Alcohol Microbubble Response to High MI Ultrasound

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Mohammed R. A. Rashid; [2018]
   Keywords : high MI ultrasound; microbubble; PVA; mechanical index; Verasonics; contrast enhancment;

   Abstract : The induced rupturing of Poly Vinyl Alcohol (PVA) microbubbles with high mechanical index (MI)ultrasound beam is used in multiple medical application such as drug delivery, image contrastenhancement and perfusion imaging.In this work, Triggered imaging technique with subtraction algorithm is used to enhance themicrobubble’s (MB) contrast over tissue (CTR).

5. 4. Subharmonic Imaging of Polymer-Shelled Contrast Agents

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rúnar Sigmundsson; [2018]
   Keywords : Ultrasound Imaging; Contrast Enhanced Ultrasound Imaging; Contrast Agents; PVA Contrast Agents;

   Abstract : The harmonic generation due to the nonlinear behavior of Ultrasound Contrast Agents (UCAs) must be exploited for improved efficiency when imaging vascular targets in the neighborhood of highly echogenic tissue. One may even further improve the efficiency by focusing on the subharmonic generation of the UCAs, which is an even more exclusive property than the generation of higher harmonics, for improved Contrast-to-Tissue ratio (CTR).

6. 5. From RF signals to B-mode Images Using Deep Learning

   University essay from KTH/Medicinteknik och hälsosystem

   Author : Jing Ren; [2018]
   Keywords : Deep learning; Ultrasound; B-mode imaging; RF signals;

   Abstract : Ultrasound imaging is a safe and popular imaging technique that relies on received radio frequency (RF) echos to show the internal organs and tissue. B-mode (Brightness mode) is the typical mode of ultrasound images generated from RF signals. READ MORE
