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

Öz

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.
