Summary
Accurately measuring right ventricular (RV) volumes is crucial for heart disease patients. A new ellipsoidal shell model using dual-plane MR imaging provides a reliable and practical method for RV volume estimation.
Area of Science:
- Cardiology
- Medical Imaging
- Biomedical Engineering
Background:
- Accurate measurement of right ventricular (RV) volumes is essential for managing congenital and other heart diseases.
- Current methods like model-based techniques and Simpson's rule have limitations in accuracy and efficiency.
Purpose of the Study:
- To investigate a novel, simple geometric model for estimating RV volumes.
- To compare the accuracy of this new model with established methods using cardiac imaging.
Main Methods:
- A retrospective study compared RV volumes calculated using a new ellipsoidal shell model with dual-plane cine magnetic resonance (MR) imaging.
- Results were validated against multislice calculations derived from biplane cineangiography.
Main Results:
- High correlation (r = 0.98) was found between the ellipsoidal shell model and dual-plane cine MR imaging for RV volume estimation.
- Excellent correlation (r = 0.93) was also observed when comparing calculated right and left stroke volumes.
Conclusions:
- The ellipsoidal shell model offers a reliable and practical approach for estimating RV volumes.
- This technique, when used with dual-plane MR imaging, can be a valuable tool in clinical cardiology.

01:29Volumes of Solids of Revolution
Volumes of irregularly shaped objects can be systematically determined using the concept of solids of revolution. This approach begins with a region defined by a curve in a two-dimensional plane. When this region is rotated about a fixed line, known as the axis of revolution, it generates a three-dimensional object with rotational symmetry. Such objects frequently arise in mathematical modeling, physics, and engineering applications.When the region being rotated lies directly against the axis...
01:25Finding Volume Using Cross-Sectional Area
For solids whose cross-sectional areas vary in a predictable way, volume can be determined by integrating these areas along an axis perpendicular to the slices. This approach is particularly useful for polyhedral solids, where classical geometric formulas may not be immediately applicable. A tetrahedron provides a clear example of how cross-sectional integration can be applied to a three-dimensional object with continuously changing geometry.Consider a tetrahedron with height h and a base that...
01:13Problem Solving: Volume
The volume of a fuel tank mounted on the wing of a jet aircraft can be modeled using the concept of solids of revolution. In this case, the tank is formed by rotating a two-dimensional region, defined by a mathematical function, about the x-axis. The region extends along the axis from zero to two meters, and the resulting three-dimensional shape is symmetric about the axis of rotation. Because the boundary curve lies directly against the axis, the disk method is an appropriate technique for...
