Koherent saçılma üzerine moleküler girişimin etkisi

Abstract

Koherent saçılma üzerine moleküler girişimin etkisi, insan dokuları (karaciğer, böbrek, kas ve yağ) için çalışılmıştır.  Koherent saçılma tesir kesitleri nümerik integrasyonla hesaplanmıştır.  Moleküler form faktörlerin hesabı, x=sin (q/2)/l ile formüle edilen momentum transfer değişkeninin bir fonksiyonu olarak, dokuyu oluşturan farklı elementlerin küçük konsantrasyonlarının varlığında gerçekleştirilmiştir.  Moleküler form faktörlerin teorik değerlerinin, deneysel verilerin olmadığı bölgede (x ≥ 1 Å^-1) kullanılabileceği görülmüştür.  Dokuların koherent saçılmasının hesabı üzerine verilerin eksikliğinden dolayı, bu çalışmanın sonuçları literatürde değerli bilgi temin edecektir.

The effect of molecular interference on coherent scattering

Abstract

The effect of molecular interference on coherent scattering is studied for human tissues (liver, kidney, muscle and fat). The coherent scattering cross sections are computed by numerical integration. The calculation of molecular form factors is performed as function of the momentum transfer variable formulated with x=sin (q/2)/l in the presence of small concentrations of different elements constituting tissue. It is seen that theoretical values of molecular form factors can be used in the region (x ≥ 1 Å^-1) where there is no experimental data. Because of the lack of data on calculation of coherent scattering of tissues, the results of this study will provide valuable knowledge in literature.
