  1. 21. Bone segmentation and extrapolation in Cone-Beam Computed Tomography

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zaineb Amor; [2020]
    Keywords : ;

    Abstract : This work was done within the French R&D center of GE Medical Systems and focused on two main tasks: skull bone segmentation on 3D Cone-Beam Computed Tomography (CBCT) data and skull volumetric shape extrapolation on 3D CBCT data using deep learning approaches. The motivation behind the first task is that it would allow interventional radiologists to visualize only the vessels directly without adding workflow to their procedures and exposing the patients to extra radiations.

  3. 22. Design of 3D-printed cranioplasty moulds using Neural Network

    University essay from Lunds universitet/Matematik LTH

    Author : Jonathan Andersson; [2020]
    Keywords : Cranioplasty; Neural Network; Convolutional Neural Network; autoencoder; 3D printing; data reconstruction; Technology and Engineering; Medicine and Health Sciences; Mathematics and Statistics;

    Abstract : Cranioplasty is surgical repair of a skull bone defect due to a previous surgery or injury. Cranioplasty is most often performed with autologous bone flap, i.e the patient's own saved bone from previous surgery if this is available. READ MORE

  4. 23. Skull Reconstruction Using Statistical Shape Models

    University essay from Lunds universitet/Matematik LTH

    Author : Patrik Rosendal; [2020]
    Keywords : Skull Reconstruction; PCA; ICP Registration; Mathematics and Statistics;

    Abstract : In case of a head injury or trauma a surgeon opens up the skull by removing a bone piece of the skull to either relieve pressure or get access to brain tissue. The first option is to follow up with putting back the same skull piece. READ MORE

  5. 24. Kontrollerad postanestetisk uppvakning med ett justerbart tak : fysiologiska effekter av stress hos shetlandsponnyer under uppvakningsperioden

    University essay from SLU/Dept. of Clinical Sciences

    Author : Lisa Nilson Hissa; Emelie Margareta Helena Törnqvist; [2020]
    Keywords : häst; anestesi; uppvakning; assisterad uppvakning; assisterad resning; stress;

    Abstract : Hästars uppvakning efter anestesi innebär många risker. Detta bidrar till att mortaliteten vid hästanestesi är mycket högre jämfört med mortaliteten vid anestesi av smådjur och människor. Hästars naturliga flyktbeteende gör ofta att de försöker resa sig innan narkosläkemedlen eliminerats. READ MORE

  6. 25. Modelling of Laser Welding of Aluminium using COMSOL Multiphysics

    University essay from KTH/Materialvetenskap

    Author : Jie Chen; [2020]
    Keywords : laser welding process; aluminium alloy; thermal-mechanical; COMSOL Multiphysics; hot cracking; thermal model; CFD model; mechanical model; Marangoni effect; lasersvetsningsprocess; aluminiumlegeringar; termisk-mekanisk; COMSOL-flerfysik; hetsprickning; termisk modell; CFD-modell; mekanisk modell; Marangoni-effekt;

    Abstract : This thesis presents a modelling approach of laser welding process of aluminium alloy from the thermo-mechanical point of view to evaluate the occurrence of hot cracking based on simulation results and relevant criteria. The model was created stepwise in COMSOL Multiphysics, starting with the thermal model where heat conduction of solid and liquid phase was computed. READ MORE
