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

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

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

   Sammanfattning : 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. LÄS MER

3. 2. Synthesizing of brain MRE wave data

   Master-uppsats, KTH/Medicinsk avbildning

   Författare :Maryia Yuliuhina; [2023]
   Nyckelord :MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

   Sammanfattning : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. LÄS MER
