3. Acoustic Characterization of the Cellulose-coated Perfluorocarbon Droplets based on Phase Velocity Measurements
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Today, microbubbles are one of the most commonly used ultrasound contrast agents, since their high compressibility results in a strongly scattered signal. Despite this advantage, microbubbles experience limitations by the decreased stability and large diameter. READ MORE

5. Estimating patient peak skin dose with fluoroscopic procedures
University essay from Umeå universitet/Institutionen för fysikAbstract : During image guided interventional radiology (IR) procedures, acute X-ray induced skin injuries may occur due to high absorbed patient skin dose. These procedures are highly dependent on X-ray imaging both for guiding fluoroscopy and high quality diagnostic image acquisitions. READ MORE
