Improved contralateral subtraction images by use of elastic matching technique
Medical Physics, 2000A contralateral subtraction technique has been developed to assist radiologists in the detection of asymmetric abnormalities such as lung nodules on a single chest radiograph. With this technique, a contralateral subtraction image is obtained by subtracting a right/left reversed “mirror” image from the original one. The lesions in the subtraction image

A New Technique For Elastic Registration Of Tomographic Images
SPIE Proceedings, 1988A simple algorithm for geometric registration of tomographic images was developed to be applied to images of the heart obtained by Positron Emission Tomography (PET). Commonly, image misregistrations are not only caused by simple positioning differences like translation and rotation, but also by deformations that cannot be expressed by simple geometric

Intravascular tri-modality system: Combined ultrasound, photoacoustic, and elasticity imaging
Applied Physics Letters, 2018We have developed a hybrid intravascular imaging system for the early detection of vulnerable plaque by combining three complementary imaging techniques: ultrasound imaging (USI), photoacoustic imaging (PAI), and photoacoustic elasticity imaging (PEI ...

Comparison between different elastic imaging techniques on 2D OBS data
SEG Technical Program Expanded Abstracts 2001, 2001We present a comparative study of different elastic imaging techniques, performed on a 2D OBS acquisition. We experiment three imaging methods to illuminate a given target zone. The first one is a linearized elastic inversion method using a conjugate gradient; the Green’s functions are computed by finite differences.

Surface matching of multimodality image volumes by a fuzzy elastic registration technique
Computerized Medical Imaging and Graphics, 1998Multimodality image registration is useful in diagnostic imaging and treatment planning for radiation therapy. In this paper, we present a technique which registers the surfaces of two volumes acquired by different medical imaging modalities. We represent the image volumes in terms of their surface elements known as tiles.

Three-dimensional imaging of carbon using an elastic scattering coincidence technique
Journal of Applied Physics, 2009A setup is described for an elastic scattering coincidence technique installed at an ion microprobe facility. This setup is developed for three-dimensional (3D) profiling of light elements in thin transmission targets. In the present paper, 3D imaging of carbon is demonstrated.

Robust Reconstruction of Elasticity Using Ultrasound Imaging and Multi-Frequency Excitations
IEEE Transactions on Medical Imaging, 2018Biomedical parameters of tissue can be important indicators for clinical diagnosis. One such parameter that reflects tissue stiffness is elasticity, the imaging of which is called elastography.

Image correction techniques for 3D interactive surface using a transparent elastic gels
Proceedings of the International Working Conference on Advanced Visual Interfaces, 2012There are many kinds of three dimensional displays that have been developed to date. Most of them provide 3D visual sensation to the users, but they do not provide 3D haptic feedback. On the other hand, an interactive surface system using transparent gels enables users to touch a 3D surface.

New techniques in the elastic analysis of arch bridges using image processing
Strain, 1996AbstractThe importance of the masonry arch in Britain's infrastructure has never been more significant than at the present time with ever increasing axle loads under new EEC regulations The searches have been shown to be significantly affected by the overlying fill.

Determination of elastic properties of latewood and earlywood by digital image analysis technique
Wood Science and Technology, 2019The proportion of latewood varies from species to species and from site to site. To understand the stiffness of wood structures, it is necessary to accurately determine the modulus of elasticity (MOE) of the wood. In this paper, a digital image correlation method was used to analyze the surface strain of wood specimens during tensile testing and ...
