  1. 1. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

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

    Author : Sara Mineur; [2023]
    Keywords : Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

    Abstract : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. READ MORE

  3. 2. Image Processing in MRI Guided Real-TimeAdaptive Radiotheraphy - Upsampling and Segmentation of Target Volume and Organs at Risk

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Shreyas Shivakumara; [2021]
    Keywords : ;

    Abstract : Magnetic Resonance Imaging (MRI) is a useful medical imaging technique that is used for cancer treatment.The major drawback of this method is the relatively long scan time, limiting its use for real time tracking of a potentially moving target during the radiotherapy session.

  4. 3. Reinforcement learning applied to MLC tracking

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Adithya Raju Ganeshan; [2021]
    Keywords : Reinforcement Learning; Multileaf Collimator; Magnetic Resonance Imaging; Adaptive Radiotherapy;

    Abstract : Radiotherapy has become an ever more successful treatment option for cancer.Advances in imaging protocols combined with precise therapy devices suchas linear accelerators contribute towards millimeter precision of treatmentdelivery with far fewer side effects. READ MORE

  5. 4. Real-time imaging of cerebrospinal fluid flow physiology at 7T

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Olle Haglund; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Background The cerebrospinal fluid (CSF) is involved in several diseases and patho- physiological states, such as Alzheimer’s disease and hydrocephalus. Previous studies CSF dynamics in the brain show that the flow of the CSF depends on cardiac pulsation, time of day and respiration. READ MORE

  6. 5. Developing a technique for combining light and ultrasound for deep tissue imaging

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Meng Li; [2018]
    Keywords : UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Abstract : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. READ MORE
