  1. 6. Deformable image registration using anatomical landmarks in tubular structures

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Jenny Wingqvist; [2021]
    Keywords : Medical image analysis; radiation therapy; deformable image registration; anatomical landmarks; bronchial tree; vascular tree;

    Abstract : Cancer is one of the leading causes of death in the world, but advances in research and development of treatment methods is constantly ongoing to reduce the number of deaths and the amount of suffering. One of many approaches is radiation therapy, which uses high doses of radiation to kill tumors. READ MORE

  3. 7. Automatic magnetic resonance brain volume measurements to assess the effect of minimised blood sample extraction on brain development in extremely preterm infants

    University essay from Lunds universitet/Läkarutbildningen

    Author : Hickmat Hamie; [2021]
    Keywords : Magnetic resonance imaging; Brain development; Prematurity; Medicine and Health Sciences;

    Abstract : Aim: To evaluate a pipeline for automatic MRI brain segmentation and volumetric tissue structure quantification in a cohort of extremely preterm infants. Methods: 13 extremely preterm neonates underwent MRI-scanning at a term equivalent age. Seven of these subjects had suitable MRI sequences and were analyzed in the pipeline. READ MORE

  4. 8. The Potential of Intra-fraction Monitoring of Patient Anatomy Using a Parameterized Motion Model

    University essay from Umeå universitet/Institutionen för fysik

    Author : Maya Staneva; [2019]
    Keywords : ;

    Abstract : Radiotherapy aims to strike a tumour with high accuracy, but anatomic changes and internal organ motion introduce uncertainties and therefore large margins are conventionally used to compensate for this. The MR-Linac will enable target tracking prior to and during treatment which will make daily adjustments of a treatment plan possible. READ MORE

  5. 9. Analyzing gyro data based image registration

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Olof Björck; [2019]
    Keywords : ;

    Abstract : An analysis of gyro sensor data with regards to rotational image registration is conducted in this thesis. This is relevant for understanding how well images captured with a moving camera can be registered using only gyro sensor data as motion input. This is commonly the case for Electronic Image Stabilization (EIS) in handheld devices. READ MORE

  6. 10. CAD-Based Pose Estimation - Algorithm Investigation

    University essay from Linköpings universitet/Datorseende

    Author : Annette Lef; [2019]
    Keywords : 6D pose estimation; bin-picking; point cloud; Point Pair Feature; Fast Global Registration;

    Abstract : One fundamental task in robotics is random bin-picking, where it is important to be able to detect an object in a bin and estimate its pose to plan the motion of a robotic arm. For this purpose, this thesis work aimed to investigate and evaluate algorithms for 6D pose estimation when the object was given by a CAD model. READ MORE
