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).

   Author : Dimitrios Evangelou; [2018]
   Keywords : Subharmonic Imaging; Ultraharmonic Imaging; Polyvinyl Alcohol; PVA; Verasonics; Ultrasound Contrast Agents; Non-linear imaging; Contrast-to-Tissue ratio.;

   Abstract : Ultrasound has been established as one of the most widely used imaging modalities for diagnostic purposes, due to the several advantages it provides in comparison with other techniques. Hence, ways to further improve the confidence in diagnoses provided by ultrasound are constantly being investigated. READ MORE
