Non-rigid registration of mammogram images using large displacement optical flow with extended flexibility for manual interventions
This thesis presents a registration method for mammogram images with extended flexibility for manual inputs from medical specialists. The algorithm was developed as part of the Mammography project led by Professor. Regina Barzilay at MIT CSAIL. Given a sequence of mammogram images, the algorithm …

Compact representations for fast nonrigid registration of medical images
We develop efficient techniques for the non-rigid registration of medical images by using representations that adapt to the anatomy found in such images. Images of anatomical structures typically have uniform intensity interiors and smooth boundaries. We create methods to represent such regions …

Identifying Response to Therapy in Longitudinal PET Imaging Studies
… predicting response to therapy. Additionally, registration methodology was developed to register pre- and post- therapy PET/CT images. The methodology registers pre- and post- therapy PET/CT scans by registering CT scans using customised rigid and non-rigid registration performed by the Image …

Multimodal Data Fusion for Deep Learning Applications in Intracoronary Image Segmentation
… multi-anatomical, multimodal segmentation and co-registration platform for intracoronary images. Although manual annotation and co-registration of intracoronary images from different modalities remain the gold standard today for facilitating the use of intravascular image analysis and …

Virtual-Real Object Registration and Shape Completion for Stable and Accurate Augmented Reality Technology
… widely used in many applications. 3D point cloud registration is one of the main processes to correctly align virtual 3D objects with real-world scenes in AR. The higher quality of the underlying 3D point clouds with fewer missing and noisy points, the more accurate the 3D point cloud …

Multimodal intravital imaging of tissue structure and cell dynamics in skin using integrated optical coherence and multiphoton microscopy
… for clinical applications to potentially enable non-invasive diagnosis of skin diseases. The methods presented are based on a multimodal microscope that integrates optical coherence and multiphoton microscopy. The development of the integrated microscope was focused on enabling sufficient …

3D Reconstruction of Patient Specific Bone Models for Image Guided Orthopaedic Surgery
… research often focuses on intra-operative registration of the patients' anatomy with pre-operatively obtained 3D volumetric data (e.g. CT scans) utilising fiduciary markers. This expensive and invasive approach is not routinely available for diagnostics, and a majority of fracture reduction …

Finite Element Modeling Driven by Health Care and Aerospace Applications
… computational modeling for biomechanical registration of Magnetic Resonance Imaging (MRI) in image-guided neurosurgery. Neuronavigation with deformable registration of preoperative MRI to intraoperative MRI allows the surgeon to view the location of surgical tools relative to the …
