BACKGROUND AND PURPOSE Accurate measurement of aortic annulus diameter is crucial for choosing suitable prosthetic size for transcatheter aortic valve implantation (TAVI). Several imaging methods are available for the measurement, but significant variability between different modalities has been observed. The purpose of this study was to systematically compare the measurements of aortic annulus...
Abstract Today, computer aided assessment of ultrasound video sequences is considered the gold standard. Ultrasound analysis forms an integral part of the medical research studies performed at the DLR. Currently, two studies are being performed that obtain ultrasound measurements of vascular structures. In this project, a software is developed that supports these and future studies in providing...
The ability to measure trees remotely or at a distance may be of value to forest inventory processes. Within three forest types (young coniferous, old coniferous, and deciduous), we compared laser caliper measurements collected at distances up to 12 m from each tree, to direct contact caliper measurements. Bitterlich sector-fork measurements and diameter tape measurements were also collected fo...
