  1. 1. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sara Öquist; [2020]
    Keywords : Acoustic Droplet Vaporization; Verasonics; Ultrasound; Vaporization Efficiency; Phase-change Contrast Agents;

    Abstract : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.

  2. 2. Classification of Heart Views in Ultrasound Images

    University essay from Linköpings universitet/Datorseende

    Author : David Pop; [2020]
    Keywords : AI; deep learning; echocardiography; image classification;

    Abstract : In today’s society, we experience an increasing challenge to provide healthcare to everyone in need due to the increasing number of patients and the shortage of medical staff. Computers have contributed to mitigating this challenge by offloading the medical staff from some of the tasks. READ MORE

  3. 3. Ultrasonic Assisted Drying and its Effect on 3D Printability of Minced Beef and Other Foods

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Viktor Lindström; [2020]
    Keywords : Drying; Convection drying; Ultrasound; Ultrasonic drying; 3D-Printing; 3D-Printability; Food; Meat; Beef; Food technology; Livsmedelsteknologi; Technology and Engineering;

    Abstract : The aim of this master thesis project was to investigate the impact on drying kinetics of ultrasound during air drying by a new ultrasonic transducer, on which a patent application has been filed by CSIRO. Convection drying using hot air is currently the conventional method of drying in the industry due to its simplicity and low cost. READ MORE

  5. 5. Segmentation of the Common Carotid Artery from Ultrasound Images using UNet

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Oskar Friberg; [2020]
    Keywords : MSc; Deep Learning; CNN; Computer Vision; Ultrasound; Carotid Artery; Technology and Engineering;

    Abstract : The common carotid artery (CCA), the artery that supplies our brains with oxygen, is of great importance in stroke research. The usual way to monitor the artery is by using ultrasound (US) imaging. An automated way of segmenting out the arteries from the US images is desired to optimize research. READ MORE
