  1. 6. Evaluation of Computer Tomography based Cancer Diagnostics with the help of 3D Printed Phantoms and Deep Learning

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Alex Back; Pontus Pandurevic; [2023]
    Keywords : Machine Learning; Deep Learning; Convolutional Neural Networks; Perception Loss; CNN; DL; ML; Computer Tomography; CT; Cancer Diagnostics; Evaluation of Image Reconstruction; Radiomics; Tumors; 3D Printed Phantoms; 3D Printing; PLA;

    Abstract : Computed x-ray tomography is one of the most common medical imaging modalities andas such ways of improving the images are of high relevance. Applying deep learningmethods to denoise CT images has been of particular interest in recent years. READ MORE

  3. 7. Automatic Detection of Common Signal Quality Issues in MRI Data using Deep Neural Networks

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Erika Ax; Elin Djerf; [2023]
    Keywords : mr; magnetic resonance; machine learning; deep learning; anomaly detection; U-Net; autoencoder; 3D; classification; reconstruction; artefacts;

    Abstract : Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique that provides high resolution images of soft tissue. One problem with MRI is that it is sensitive to signal quality issues. The issues can arise for various reasons, for example by metal located either inside or outside of the body. READ MORE

  4. 8. Accuracy and Reliability of 3D Scanning Spatial Data when Capturing Limb Morphology for Use within Prosthetics and Orthotics: A Scoping Review

    University essay from Jönköping University/HHJ. Ortopedteknisk plattform

    Author : Miles Bailey-Brændgaard; Peter Wibe Enevoldsen; [2022]
    Keywords : Scanner; 3D; Accuracy; Reliability; Validity; Prosthetics; Orthotics; Shape capture; Measurement; Human; Shape; Morphology; Assessment;

    Abstract : Background: Scanners are becoming widespread in Prosthetics and Orthotics, replacing plaster casting in the manufacture of some types of devices. P&O shape capture must be accurate and reliable, so the device is comfortable and reproducible between clinicians/sessions. READ MORE

  5. 9. Research and Application of 6D Pose Estimation for Mobile 3D Cameras

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

    Author : Qian Ruichao; [2022]
    Keywords : 6 Degree-of-Freedom DoF ; pose estimation; deep learning; Light Detection and Ranging LiDAR ; structure light; TrueDepth; 6 frihetsgrader DoF ; poseringsuppskattning; djupinlärning; ljusdetektion och avstånd LiDAR ; strukturljus; TrueDepth;

    Abstract : This work addresses the deep-learning-based 6 Degree-of-Freedom (DoF) pose estimation utilizing 3D cameras on an iPhone 13 Pro. The task of pose estimation is to estimate the spatial rotation and translation of an object given its 2D or 3D images. READ MORE

  6. 10. Lens Distortion Correction Without Camera Access

    University essay from Linköpings universitet/Datorseende

    Author : Emily Olsson; [2022]
    Keywords : Lens distortion; Lens distortion correction; Perspective n-Point; Camera calibration;

    Abstract : Lens distortions appear in almost all digital images and cause straight lines to appear curved in the image. This can contribute to errors in position estimations and 3D reconstruction and it is therefore of interest to correct for the distortion. If the camera is available, the distortion parameters can be obtained when calibrating the camera. READ MORE
