Since different imaging modalities can provide complementary information about cardiac anatomy and function, this thesis focuses on the integration of intra-operative ultrasound (US) with pre-operative high quality dynamic 3D magnetic resonance (MR) or computed tomography (CT) images to assist surgical ...
A computerized method for the detection and characterization of disease in an image derived from a chest radiograph, wherein an image in the chest radiograph is processed to determine the ribcage boundary, including lung top edges, right and left ribcage edges, and right and left hemidiaphragm ...
In another embodiment, a user selects one previously created workflow template and applies it to a set of medical image data for a specific medical study. Alternatively, a default workflow template may be provided to the user automatically based on the macro anatomy of the medical image data an...
Results: We demonstrate using a 4D clinical thorax dataset that a lungtumor may be well delineated from within the ribcage along longitudinal planes utilizing as few as 8 projections over 15 degrees of arc using FDK. Assuming an average patient respiration rate of 0.3Hz, gated imaging is ...

While useful for anatomy detection purposes, no regional tissue distortion is expected to occur in sliding regions, which invalidates the accuracy of regional deformation estimates from traditional DIR methods in the lungs in regions close to fissures and the pleural cavity. The main responsible for ...
