1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy
University essay from Lunds universitet/Fysiska institutionenAbstract : 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

2. Monte Carlo Localization with Hilbert maps as Likelihood Fields
University essay from KTH/Skolan för industriell teknik och management (ITM)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

3. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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. Beam refinement and beam tracking using Machine Learning Techniques in 5G NR RAN
University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskapAbstract : 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
