  1. 1. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Svante Rosenlind; [2023]
    Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

  3. 2. 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

  4. 3. Anisotropic Muscle Phantoms for Shear Wave Elastography Assessment of the Levator Ani Muscle Properties

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Bleona Koxha; Melissa Jova Martinez; [2023]
    Keywords : pelvic floor disorder; levator ani muscle; shear wave elastography; phantom; anisotropy; polyvinyl alcohol; bäckenbottenbesvär; levator ani muskel; shear wave elastografi; fantom; anisotropi; polyvinylalkohol;

    Abstract : Pelvic floor disorder is an emerging research area and is highlighted in many pelvic floor studies. Assessment methods for this type of injury are lacking and new methods for prevention and diagnosis are needed. Pelvic floor disorders are common among women and can lead to suffering for the patient. READ MORE

  5. 4. Design of a Custom Amplifier for an Ultrasound Cell Platform

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Majd Kasem Alchar; Yasmin Al-Kazaz; [2022]
    Keywords : Amplifier; PCB; LTSpice; KiCAD; EDA; ECAD.; Förstärkare; Kretskort; LTSpice; KiCAD; EDA; ECAD;

    Abstract : In cancer research, studies on cells are often done in 2D, grown on plates which are not realistic. Therefore, a specialized system is being designed to build 3D cell structures. This system requires a fitting amplifier that is of low cost and changeable gain. READ MORE

  6. 5. Deep neural network for object classification and optimization algorithms for 3D positioning in Ultrasonic Sensor Array

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Hui Zhang; [2021]
    Keywords : ultrasonic sensor; simulation; CNN; optimization; localization; object classification;

    Abstract : Ultrasonic sensors are commonly used in automobiles to assist driving maneuvers, e.g., parking, because of their cost-effectiveness and robustness. READ MORE
