  1. 1. Investigation of the magnetic fields of a young Sun-like star ∏1 UMa

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Lawen Ahmedi; [2020]
    Keywords : Magnetic field; star; young Sun; polarisation; Stokes vector;

    Abstract : In astronomy, the Sun has an important role. It keeps the solar-system together and is thesource for life, heat, light and energy to Earth. As any other star or planet, the Sun has amagnetic field. The magnetic field of the Sun has a great impact on the Sun itself as well asits surrounding. READ MORE

  5. 4. Using Fetal Myocardial Velocity Recordings to Evaluate an AI Platform to Predict High-risk Deliveries

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Hanna Baban; Olivia Grauning; [2019]
    Keywords : ;

    Abstract : Diagnosing abnormal fetal cardiac function using ultrasound is a complicated procedure which makes it difficult to obtain high quality results from ultrasound examinations that are performed shortly before delivery. Color tissue Doppler imaging (cTDI) is the echocardiographic technique that has been used to obtain the data for this project. READ MORE

  6. 5. Developing a New Method for MRI Triggering Using Doppler Ultrasound

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

    Author : Usama Gazay; [2019]
    Keywords : ;

    Abstract : Purpose: Magnetic Resonance Imaging (MRI) is a medical imaging technique used in radiology to produce high quality images of the anatomy and the physiological processes of the body. Cardiac gating is a triggering system used for the MRI scanner to synchronize the MRI scanner with the cardiac cycle of the patient while imaging. READ MORE
