The evaluation of the bone density from 2D and 3D medical images is an important task both in clinical and research fields. Clinically it is considered one of the parameters of prediction of osteoporosis and therefore bone fracture risk1. It is commonly measured using the Dual Energy Xray ...
A method for the analysis of bone mineral density and/or bone structure from x-ray images using calibration phantoms which act as references in order to determine bone structure from an x-ray image. Regions of anatomical interest (ROI) in the image are identified. The method comprises: obtaini...
Cancellous Bone Structure: Analysis of High-Resolution CT Images with the Run-Length Method Quantitative computed tomography is extensively used to assess bone density; its potential to quantify bone structure, however, remains to be explored. In ... EP Durand,P Rüegsegger - 《J Comput Assist ...
The songs of birds, some of which are wonderful to listen to, are the ultimate signal (usually males to other male birds) of the singer’s territorial imperative, and any intrusions into it will be dealt with harshly. If one male is foolish enough to ignore the message of territoriality f...
Implant stability was measured by means of resonance frequency analysis (RFA) and damping capacity assessment (Periotest, PTV). Bone density (Hounsfield units) was measured at different regions of interest (ROI) and cortex thickness was measured around each implant. Results Implant stability correlated...

The goal of this study was to assess whether a high-resolution CT measure of trabecular bone structure can enhance the discrimination between subjects with or without a vertebral fracture and having overall low hip or spine bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA). ...
(CNV), exemplifies the need for a multimodal approach: (1) color fundus (CF) photography effectively highlights areas of hemorrhage and the presence of fibrovascular tissue; (2) fluorescein angiography (FA) reveals subtle leaks associated with CNV that are not always visible to the naked eye; ...
A deep learning-based multi-view approach to automatic 3D landmarking and deformity assessment of lower limb Article Open access 02 January 2025 Deep learning methods allow fully automated segmentation of metacarpal bones to quantify volumetric bone mineral density Article Open access 06 May 2021 ...
The bone density of five proximal femurs from female cadavers was measured with computed tomography using a pixel size of 1.2 mm. A three dimensional reconstruction was performed along four well-defined axes. The region of maximal relative bone density correlated well with a previous report of the...
