  1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ibtisam Dahir Ahmed; [2023]
    Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE

  3. 2. Compensating for ultrasound frequency attenuation in tissue when determining tissue effective particle size

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Karolina Sandell; [2021]
    Keywords : Technology and Engineering;

    Abstract : Giant cell arteritis is a disease the affects the arteries, for example the temporal artery. When affecting the temporal artery, it can cause serious consequences such as blindness and stroke. The existing methods for diagnosing the disease are invasive, time consuming and costly. READ MORE

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Erik Backman; [2021]
    Keywords : kalv; tillväxt; hull; juverparenkym;

    Abstract : I den här studien undersöktes kalvar som tilläts dia fritt från sina mammor, avseende hullutveckling och tillväxt av juverparenkym under den första månaden i livet. Detta eftersom det finns en oro att kalvar som får dia fritt blir överviktiga. READ MORE

  5. 4. Investigation of Light and Ultrasound Injected Signals in Microphones

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Robin Djerv; [2021]
    Keywords : LightCommands; DolphinAttack; MEMS Microphone; Signal Injection; Security;

    Abstract : Voice commanded systems (VCS) have been proved to be vulnerable to signal in- jections mimicking voice commands and explored security flaws in market avail- able products for the time of each respective study. Signal injection caused with the help of amplitude modulated ultrasonic waves (being known as DolphinAt- tacks - DA) were proved to work on several such devices in 2017. READ MORE

  6. 5. Development of a Tool for Imaging the Pumping-Out Behavior of Poly- Vinyl Alcohol Shelled Microbubbles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Stina Hägglund; [2020]
    Keywords : Microbubbles; Pumping-out behavior; Verasonics; Ultrasound; Ultrafast imaging;

    Abstract : 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. READ MORE
