- Assist in medical clinical evaluation and surgical planning by estimating the volumes of complicated 3D shapes of targets of interest Objective documentation of progress of aneurysms, tumors and other 3D objects as opposed to simple visual evaluation Analysis of geological images, such as calculation of underground volumes of lava or oil Quantification of other objects with irregular shapes such as fire or smoke
- 详细技术说明
- Researchers at UCLA have identified a modified illusory surface algorithm that uses the curvature and a few points on the surface of an irregular 3D object to accurately calculate its volume. By segmenting images given to the computer using user-selected points, the algorithm quickly and accurately obtains geometrical information about the structure with minimal user interaction. After the algorithm has calculated its estimate of the volume, a new image can be generated with the calculated data for comparison to the original image, verifying the accuracy of the calculations visually. This imaging system can segment and compute the geometry of aneurysms, tumors, thromboses, inflammations, foreign objects, organs and any other structures which can be identified in images or reconstructed into 3D objects.
- *Abstract
-
UCLA investigators have identified an effective and accurate algorithm for calculating the volume and surface of irregularly shaped 3D structures from points selected on an image. This method can be used to calculate geometric information for a wide range of multi-dimensional objects and has been tested accurately on calculating the size of brain aneurysms

State of Development
The method of analysis was successfully tested on brain aneurysm images. Future improvements to the algorithm will include the ability to analyze diverse aneurysm shapes and adapting the algorithm for different clinical purposes.
Background
Ruptured brain aneurysms account for over 5% of all stroke cases with a high fatality rate. Often, these brain aneurysms went undetected or were misdiagnosed in size due to inaccurate methods of estimating volume of aneurysms. Because the risk of aneurysm rupture increases as the size of the aneurysm becomes larger, it is extremely important to have an accurate method of determining its size. Currently, methods range from segmenting images to deforming a shape of known volume to fit the target. However, these techniques are often labor intensive, time consuming, and impractical with a wide range of accuracy. Complicated shapes such as the human right ventricle cannot usually be quantified with existing technology.
