3-D Elastic Matching Technique for Temporal Subtraction Employing Thorax MDCT Images

2007
Detection of subtle lesions on CT images is a difficult task for radiologists, because subtle shadows tend to have low contrast, and a large number of CT images must be interpreted in a limited time. A temporal subtraction image, which is obtained by subtraction of a previous image from a current one, can be used for enhancing interval changes (such as

A composite imaging technique for high frame-rate and full-view cardiovascular ultrasound and elasticity imaging

2012
The frame-rate of ultrasound radio-frequency (RF) data acquisition is critical for imaging of the pulse wave and electromechanical wave propagation in cardiovascular tissues as well as improving the strain estimation. Therefore, an automated method had been developed to overcome the frame-rate limitations on standard systems by retrospective multi ...

Burgers vector determination of dislocations in an elastically anisotropic crystal by high-order reflection imaging technique in a HVEM

Philosophical Magazine A, 1984
Abstract Dislocations in β-CuZn have been examined by weak-beam imaging and by high-order reflection imaging in a HVEM. It has been shown that under these imaging conditions the conventional invisibility criterion g·b = 0 is valid, even in such an anisotropic crystal as β-CuZn.
