A Hybrid Method for Automatic Anatomical Variant Detection and Segmentation
The delineation of anatomical structures in medical images can be achieved in an efficient and robust manner using statistical anatomical organ models, which has been demonstrated for an already considerable set of organs, including the heart. While it is possible to provide models with sufficient shape variability to cope, to a large extent, with inter-patient variability, as long as object to...
متن کاملAutomatic Aortic Root Segmentation with Shape Constraints and Mesh Regularisation
A non-invasive procedure called Transcatheter Aortic Valve Implantation (TAVI) has emerged as an alternative procedure for patients suffering with aortic stenosis, but cannot undergo standard open-heart surgery. A full segmentation of the aortic root is important to the success of the procedure, and is essential for patient selection, procedural planning, and post-evaluation [1]. We propose a f...
متن کاملAutomatic Syllable Detection for Vowel Landmarks
Lexical Access From Features (LAFF) is a proposed knowledge-based speech recognition system which uses landmarks to guide the search for distinctive features. The first stage in LAFF must find Vowel landmarks. This task is similar to automatic detection of syllable nuclei (ASD). This thesis adapts and extends ASD algorithms for Vowel landmark detection. In addition to existing work on ASD, the ...
متن کاملPopulation screening for TAVI procedure
Background Transcatheter aortic valve implantation (TAVI) is an alternative that offers hope to patients who are older, or have contraindication to conventional surgical aortic valve replacement due to considerable comorbidities. In our country there is about 500 to 1000 patients, older than 80 years needing this, less invasive procedure. The aim of this study was to asses the number of high-ri...
متن کاملProcedure Planning: Anatomical Determinants of Strategy
In contemporary practice there are three main methods that can be employed when attempting to open a chronic total occlusion (CTO) of a coronary artery; antegrade or retrograde wire escalation, antegrade dissection re-entry and retrograde dissection re-entry. This editorial will attempt to clarify the anatomical features that can be identified to help when deciding which of these strategies to ...
