The present tomograph makes reconstruc tions at intervals of 20 ms. Because of a lack of clear (intramural) landmarks (except the roots of the papillairy muscle), it is difficult to pinpoint spatial trajectories of particular points in the heart. Therefore, a second method was developed of injecting radiopaque markers in the heart and following their motion patterns during the cardiac cycle with help of a biplane X-ray equipment. The data obtained with both methods can be implemented in our finite element model of the heart to compute intramural stresses and strains. The results obtained sofar with the extended Darcy equation to account for the interaction of blood rheology and tissue mechanics look promising. Further testing with more sophisticated subjects than mentioned in Figure 9 is required before it will be implemented in our finite element model of the heart. We conclude that analysis of regional cardiac function, including regional myocardial blood flow, requires still a major research effort but the results obtained sofar justify, to our opinion, a continu | | 出版日期 | Book 1985 | | 关键词 | cardiac imaging; cardiovascular; cardiovascular system; electrocardiography; heart; ultrasound | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-4992-8 | | isbn_softcover | 978-94-010-8710-0 | | isbn_ebook | 978-94-009-4992-8Series ISSN 0166-9842 | | issn_series | 0166-9842 | | copyright | Martinus Nijhoff Publishers, Dordrecht 1985 |
