SPECT Compton-scattering correction by analysis of energy spectra.
The hypothesis that energy spectra at individual spatial locations in single photon emission computed tomographic projection images can be analyzed to separate the Compton-scattered component from the unscattered component is tested indirectly. An axially symmetric phantom consisting of a cylinder with a sphere is imaged with either the cylinder or the sphere containing 99mTc. An iterative peak...
متن کاملStudy of the Compton scattering effect of soft tissue in PET imaging by Monte Carlo method
Introduction:In PET imaging, one or both of two annihilation photons may change the direction before reaching the detector due to Compton scattering interaction in body. .Methods:This article, a Monte Carlo simulation study, examined the effect of soft tissue on this error.In this work, the PET BiographTM 6 scanner, a simple geometry of soft tissue -including a sphere of soft tissue in center ...
متن کاملCoherent Compton scattering on light nuclei in the ∆-resonance region
Coherent Compton scattering on light nuclei in the ∆ resonance region is studied in the impulse approximation and is shown to be a sensitive probe of the in-medium properties of the ∆ resonance. The elementary amplitude on a single nucleon is calculated from the unitary K-matrix approach developed previously. Modifications of the properties of the ∆ resonance due to the nuclear medium are accou...
متن کاملHadronic light-by-light scattering effect on muon g-2.
The hadronic light-by-light scattering contribution to muon g −2 is examined using low energy effective theories of QCD, the Nambu-Jona-Lasinio model and hidden local chiral symmetry, as guides. Our result is −36 × 10 −11 with an uncertainty of ±16 × 10 −11 , which includes our best estimate of model dependence. This is within the expected measurement uncertainty of 40 × 10 −11 in the forthcomi...
متن کاملCompton Scattering
In the early 20th century, research into the interaction of X-rays with matter was an emerging field. It was observed that when a beam of X-rays is directed at an atom, an electron is ejected and the light is scattered through an angle θ, as illustrated below. Classical electromagnetism predicts that the wavelength of scattered rays should be equal to the initial wavelength; however, experiment...
