Beyin dokusunun moleküler saçılma fonksiyonu verileri

Abstract

Fotonların madde ile etkileşimi, ortama enerji aktarımının incelenmesi açısından büyük önem taşır. Enerji aktarımı konusundaki en duyarlı çalışmalar Monte Carlo benzetişim uygulamalarıdır. Monte Carlo modellemede inkoherent saçılımın hesaplanması aşaması önem arzetmektedir. Fotonun bir ortamda inkoherent saçılma yapması, saçılma açısı ve ortama enerji aktarımı bakımından belirleyicidir. İnkoherent saçılma katsayılarının Monte Carlo modelleme programının içerisine katılmasıyla, maddede etkileşen farklı enerjili fotonların zayıflama özelliklerinin belirlenmesi mümkün olacaktır. Bu çalışmada, moleküler İnkoherent saçılma katsayılarının hesaplanması için gerekli olan inkoherent saçılma fonksiyonları, beyaz ve gri beyin maddesinin moleküler içeriğine göre atomik veriler kullanılarak elde edilmiştir. Sonuçlarımızın, deneysel çalışan ve modellemeler yapan araştırmacılar için yararlı olacağına ve kullanılabileceğine inanmaktayız.

Molecular scattering function data of brain tissue

Abstract

The interaction of photons with matter is of great importance for the study of energy transfer to the medium. The most sensitive studies on energy transfer are Monte Carlo simulation applications. In Monte Carlo modeling, the calculation of incoherent scattering is important. The incoherent scattering of a photon in a medium is decisive in terms of scattering angle and energy transfer to the medium. By incorporating the incoherent scattering coefficients into the Monte Carlo modeling program, it will be possible to determine the attenuation properties of photons of different energies interacting in the matter. In this study, incoherent scattering functions necessary for calculating molecular incoherent scattering coefficients were obtained by using atomic data according to the molecular content of white and gray brain matter. We believe that our results can be used and will be beneficial for researchers who make models and work experimentally.
