Study of the influence of propagator amplitude correction on image amplitude using beamlet propagator with local WKBJ approximation
نویسندگان
چکیده
Localized WKBJ correction based on Local Cosine Basis (LCB) beamlet propagator is applied in postand pre-stack migration to study its influence on image amplitude. 2D SEG/EAGE salt model is used for demonstration. The results indicate that localized WKBJ correction have some improvement on the image amplitude though not very dramatic for 2D SEG/EAGE salt data with relatively smalloffset acquisition. The image after acquisition aperture correction is greatly improved in the entire model. The acquisition aperture correction has larger effect on the image amplitude for migration with limited acquisition aperture in general heterogeneous media.

Lateral velocity variation related correction in asymptotic true-amplitude one-way propagators
Much work has been done on the vertical velocity variation related amplitude correction term in the asymptotic trueamplitude one-way wave equation, but the lateral velocity variation related correction has not received much attention, even being excluded in some asymptotic true-amplitude oneway propagator formulations. Here we investigate the effects of different amplitude correction terms in t...
متن کاملHigh-energy quark-quark scattering and the eikonal approximation
The high–energy quark–quark scattering amplitude is calculated first in the case of scalar QCD, using Fradkin’s approach to derive the scalar quark propagator in an external gluon field and computing it in the eikonal approximation. The results are then extended to the case of “real” (i.e., fermion) QCD. The high–energy quark–quark scattering amplitude turns out to be described by the expectati...
متن کاملThe off-shell Veneziano amplitude in Schnabl gauge
We give a careful definition of the open string propagator in Schnabl gauge and present its worldsheet interpretation. The propagator requires two Schwinger parameters and contains the BRST operator. It builds surfaces by gluing strips of variable width to the left and to the right of off-shell states with contracted or expanded local frames. We evaluate explicitly the four-point amplitude of o...

A systematic method for calculating higher-order corrections of the relativistic semiclassical fixed-energy amplitude is given. The central scheme in computing corrections of all orders is related to a time ordering operation of an operator involving the Van Vleck determinant. This study provides us a new viewpoint for quantization. PACS 03.20.+i; 04.20.Fy; 02.40.+m Typeset using REVTEX ∗e-mail...

Background: Since tumors located in thorax region of body mainly move due to respiration, in the modern radiotherapy, there have been many attempts such as; external markers, strain gage and spirometer represent for monitoring patients’ breathing signal. With the advent of fluoroscopy technique, indirect methods were proposed as an alternative approach to extract patients’ breathing signals...
