| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | CCTA (Coronary Computed Tomography Angiography) offers not only diagnostic capability matching that of CAG (Coronary Angiography) which is the gold standard of the cardiovascular diagnosis, but also a less invasive examination. However, if calcified plaque adheres to a vessel wall, high-intensity shading evoked by calcium (the main constituent of the calcified plaque), called the blooming artefacts, causes to make it difficult to diagnose the vessel stenosis. In this study, we propose a novel method to semi-automatically remove calcified plaques, which hinder the diagnosis of a stenosed coronary artery, from a CCTA image. We evaluate the efficacy of the method using the CCTA and OCT (Optical Coherence Tomography) images acquired from eight patients. | |
