  1. 1. Simulating metal ct artefacts for ground truth generation in deep learning.

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Arthur Barakat; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

  3. 2. Vöron - Vision through earsProviding visual assistance to blind or visually impaired people

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Shubham Saraswat; [2022]
    Nyckelord :;

    Sammanfattning : In this thesis, we propose an assistance system for visually impaired people, using computer vision on a raspberry pi, together with bone conduction headphones. The device captures the images using a camera, detects important objects in the view and generates speech to inform the user about the objects in the way through bone conduction headphones. LÄS MER

  4. 3. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Måns Boll; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  5. 4. Bits & Bobs : Finds from a research excavation of Birka’s rampart: A study with focus on material distribution and metal conservation

    Master-uppsats, Stockholms universitet/Arkeologiska forskningslaboratoriet

    Författare :Mikael Heljeback; [2019]
    Nyckelord :Archaeology; Metal conservation; Birka; Rampart; Iron age; Viking; Excavation; XRF; Comb; Beads; Osteoarchaeology; Ceramics; Hillfort; Artefacts; Database; Corrosion;

    Sammanfattning : In the spring of 2018, a prospection and subsequent research excavation of a previously unstudied area related to the rampart of the Viking age town of Birka, Sweden, was undertaken by students and professors from the archaeological science department affiliated with Stockholm University.The purpose of this paper is to examine and categorise the various excavated finds, the ensuing conservation and preservation of the metal objects as well as to investigate the context and possible function of the site regarding the spatial distribution of said finds.

    Sammanfattning : The middle ear is a complex organ with multiple functions. It is prone to accidental, genetic, excessive noise exposure, or age-related damage. Its main role is to convey and amplify the mechanical vibrations of the tympanic membrane to the acoustic nerve through three connected small bones, the ossicles; malleus, incus, and stapes. LÄS MER
