  1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    University essay from Lunds universitet/Fysiska institutionen

    Author : Klara Stefansson; [2024]
    Keywords : Technology and Engineering;

    Abstract : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. READ MORE

  3. 2. Monte Carlo Localization with Hilbert maps as Likelihood Fields

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ALEXANDER WALLÉN KIESSLING; [2023]
    Keywords : Localization; Monte Carlo; Mapping; Hilbert maps; Observation Likelihood model.; Lokalisering; Monte Carlo; Kartläggning; Hilbert kartor; Sensor modell.;

    Abstract : This work focuses on using sparse Hilbert maps as continuous likelihood field observation models, instead of utilizing traditional beam observation models. This observation model is integrated with a Monte Carlo Localization scheme, and localization is simulated in randomly generated 2D mazes. READ MORE

  4. 3. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sara Falk; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE

  5. 4. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
    Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  6. 5. Beam refinement and beam tracking using Machine Learning Techniques in 5G NR RAN

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Harshal Patel; [2021]
    Keywords : ;

    Abstract : Abstract: Growing needs of communication, demands a higher data transmission rate in 5G NR. In the 3rd generation partnership project (3GPP), frames are used to schedule the data to be transferred between the cellular base station (gNB) and user equipment (UE). READ MORE
