This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The task of obtaining high-quality time-resolved volumetric images of the heart has challenged the minds of imaging researchers for decades. While this problem is difficult, the high incidence of cardiovascular disease (CVD) in the developed world makes this problem all the more urgent. CVD is currently the most common cause of death in the United States. In this context, the role of imaging is dual; it can provide early diagnosis and can also enable cost-effective treatment of heart disease. This dissertation focuses on how to perform cardiac computed tomography (CT), while delivering a minimal dose of ionizing radiation. The enabling technology is the prior image constrained compressed sensing (PICCS) image reconstruction framework, which was developed and implemented at the University of Wisconsin-Madison. Two applications of PICCS are examined: CT myocardial perfusion imaging and time-resolved interventional cardiac cone-beam CT. Several technical issues specific to these applications are described and evaluated. The performance of the method is characterized using quantitative image quality metrics so as to determine its limitations. Based on the results presented in this dissertation, one should better understand the potential role of PICCS in cardiac CT at the diagnostic and the interventional levels.

Download or read book Automated Quantitative Analysis of Cardiac Medical Images written by Xiaowei Ding and published by . This book was released on 2015 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies in clinical medicine often demand the quantitative analysis of medical images. These tasks need careful and time-consuming tracing and labeling on fine image structures, cost expensive medical expert labor and often suffer from low reproducibility. We present a collection of methods that quantify important parameters from cardiac computed tomography (CT) and magnetic resonance imaging (MRI) in a fully-automated mode. We first present atlas-based segmentation, active contours models and graph-based segmentation which are components in our novel framework. We then present our algorithms for automated quantification of epicardial fat volume (EFV) from non-contrast cardiac CT, automated pericardial fat volume (PFV) quantification from water\/fat-resolved whole-heart non-contrast coronary magnetic resonance angiography (MRA) and automated coronary calcium scoring (CCS) from non-contrast cardiac CT images. Algorithm quantification results are validated on test scans with ground truth annotated by expert radiologists. Our approaches may potentially be applied in a clinical setting, allowing for accurate quantification of EFV, PFV and CCS without tedious manual tracing.

Download or read book Spectral Photon Counting Computed Tomography written by Katsuyuki Taguchi and published by CRC Press. This book was released on 2020-07-14 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral, Photon Counting Computed Tomography is a comprehensive cover of the latest developments in the most prevalent imaging modality (x-ray computed tomography (CT)) in its latest incarnation: Spectral, Dual-Energy, and Photon Counting CT. Disadvantages of the conventional single-energy technique used by CT technology are that different materials cannot be distinguished and that the noise is larger. To address these problems, a novel spectral CT concept has been proposed. Spectral Dual-Energy CT (DE-CT) acquires two sets of spectral data, and Spectral Photon Counting CT (PC-CT) detects energy of x-ray photons to reveal additional material information of objects by using novel energy-sensitive, photon-counting detectors. The K-edge imaging may be a gateway for functional or molecular CT. The book covers detectors and electronics, image reconstruction methods, image quality assessments, a simulation tool, nanoparticle contrast agents, and clinical applications for spectral CT.

Download or read book MRI from Picture to Proton written by Donald W. McRobbie and published by Cambridge University Press. This book was released on 2017-04-13 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: MR is a powerful modality. At its most advanced, it can be used not just to image anatomy and pathology, but to investigate organ function, to probe in vivo chemistry, and even to visualise the brain thinking. However, clinicians, technologists and scientists struggle with the study of the subject. The result is sometimes an obscurity of understanding, or a dilution of scientific truth, resulting in misconceptions. This is why MRI from Picture to Proton has achieved its reputation for practical clarity. MR is introduced as a tool, with coverage starting from the images, equipment and scanning protocols and traced back towards the underlying physics theory. With new content on quantitative MRI, MR safety, multi-band excitation, Dixon imaging, MR elastography and advanced pulse sequences, and with additional supportive materials available on the book's website, this new edition is completely revised and updated to reflect the best use of modern MR technology.
