1. 1. 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).

3. 2. Comparison and Optimization of Insonation Strategies for Contrast Enhanced Ultrasound Imaging

   University essay from Biomedicinsk instrumentteknik; Tekniska högskolan

   Author : Vaka Narasimha Reddy; [2012]
   Keywords : Introduction to Medical Ultrasound; Ultrasound Contrast Agents; Ultrasound Contrast for Carotid Plaques; Contrast enhanced ultrasound imaging; Bubble Theory; Nonlinear imaging; Ultrasound imaging; Pulse inversion; Cadence contrast pulse sequence;

   Abstract : Evolution of vulnerable carotid plaques are crucial reason for cerebral ischemic strokes and identifying them in the early stage can become very important in avoiding the risk of stroke. In order to improve the identification and quantification accuracy of infancy plaques better visualization techniques are needed. READ MORE
