1. Development of a Tool for Imaging the Pumping-Out Behavior of Poly- Vinyl Alcohol Shelled Microbubbles
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : For many years, microbubbles have been used as ultrasound contrast agents to improve the quality of diagnostics, seeing that they produce more backscattering ultrasound than blood does. Novel types of microbubbles and increased knowledge about their different behaviors have led to other suggested areas of use. LÄS MER
2. Non-invasive ultrasound measurements of vascular impedance
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Despite its introduction in the early 1950´s, vascular impedance has yet to be applied in clinical use to predict early stages of cardiovascular disease (CVD). It is defined as the ratio between blood pressure and flow and describes the opposition to blood flow within the cardiovascular system. LÄS MER
3. Comparison of Pushing Sequences for Shear Wave Elastography
Master-uppsats, KTH/Skolan för teknik och hälsa (STH)Sammanfattning : Shear wave elastography is a medical imaging modality in which tissue elasticity is estimated by measuring the speed of ultrasound-induced shear waves. This study aimed to implement four shear wave generating pushes and compare their performance according to chosen metrics. LÄS MER
