Three-dimensional imaging of the carpus
Annales de Chirurgie de la Main et du Membre Supérieur, 1990Since 1987, the authors have developed three-dimensional (3D) imaging of the carpus. This reconstruction based on 30 CT scans of the carpus is a new approach to imaging and allows spatial visualisation of the complex shapes of the carpal skeleton from all angles.

Three-dimensional imaging of the wrist
The Journal of Hand Surgery, 1985The objective of this study was to determine the diagnostic quality of three-dimensional images of the carpal bones that could be constructed from raw data obtained from a computerized tomography scan. The quality of raw data collected was determined by collimation, slice interval, the number of projections, and x-ray tube operating specifications. The

Three-dimensional ultrasound imaging
Current Opinion in Anaesthesiology, 2015Ultrasound guidance is frequently utilized for needle placement and observation of local anesthetic spread when performing peripheral nerve blocks. Although there is evidence that ultrasound technology can reduce complications, there are limitations to 2-dimensional (2-D) ultrasound. Three-dimensional (3-D) and especially real-time 3-D (4-D) ultrasound

Three-dimensional imaging in ultrasound
Journal of Medical Systems, 1982Ultrasonic three-dimensional images are constructed by “stacking” B-scan tomograms or ultrasonic CAT scans with a computer algorithm for subsequent perspective or sectional display. Perspective images of surfaces representing Doppler measurements of fluid velocity are illustrated in combination with isovelocity contours for flows through a flexible ...

Three-dimensional ultrasound imaging
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2010This review is about the development of three-dimensional (3D) ultrasonic medical imaging, how it works, and where its future lies. It assumes knowledge of two-dimensional (2D) ultrasound, which is covered elsewhere in this issue. The three main ways in which 3D ultrasound may be acquired are described: the mechanically swept 3D probe, the 2D ...

Three-dimensional electrocardiographic imaging
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005We review our recent work on the development and evaluation of three-dimensional electrocardiographic imaging technology (3DEIT). Cardiac electrophysiological properties, including activation time and transmembrane potentials, are estimated from body surface ECG signals with the aid of a realistic geometry heart model in which electrophysiological a ...

Since cells and tissues are inherently three-dimensional (3D), 3D imaging techniques are required to study them. 3D light microscopy offers a noninvasive, minimally destructive option for obtaining spatial and volumetric information about the structure and function of cells and tissues. 3D image data acquired with confocal or multiphoton microscopy can

Modern medical imaging provides essential preoperative knowledge of patient anatomy and pathology. This imaging is composed of many kinds of techniques and protocols, the choice of which is fully dependent on the targeted structures that practitioners want to see and analyse. Virtual reality can then be used to facilitate interpretation.

Three Dimensional Image Inpainting
2006Recently the method restoring an old picture using the local differential equation on the basis of the geometric measure is proposed. It is necessary to restore an old film and a medical image with noise as well as an old picture. So we extend the method applying for the two dimentional image such as a picture to the three dimensional image such as a ...
