Measurements of X-ray scatter signatures for some tissue-equivalent materials

Determination of the elemental composition of tissues of the cardiovascular system by atomic spectrometry, mass spectrometry and X-ray spectrometry methods

“…For this reason, in some cases synthetic standard mixtures which imitate the organic matrix are used instead of biosamples for direct ele mental analysis of biosamples. In addition, scattering properties of the matrix of biological samples and syn thetic materials analogues are tested [109,[123][124][125]. Also a number of semi empirical mathematical mod els [78] are used for the determination of chemical ele ments in the samples of organic origin (in biotissues, in particular) but it implies some restrictions on the experimental conditions and the sample itself.…”

Determinação das propriedades de atenuação de materiais radiologicamente equivalentes a tecidos humanos utilizando um equipamento DECT

“…Os phantoms são construídos para serem estáveis, suportando longas rotinas de testes sem alterar suas características físicas e químicas. Por consequência, podem ser usados para calibração e controle de qualidade de equipamentos radiológicos, estudos de dosimetria, treinamento de profissionais em aplicações clínicas, no desenvolvimento de pesquisas científicas e no monitoramento das radiações na terapia médica (6,7).…”

Coherent X-ray scattering data for plastics

“…The determination of significant variation between the structural properties of different molecules and complex structures is available by using coherent scattering [1]. In the diagnostic x-ray energy range, there are interference effects due to the coherence of elastic scattered photons, mainly at small-angles, which causes a unique scattering signature, characteristic for each material [2]. The simulation needed to be modified to more accurately model the coherent scattering in molecules and complex structures including the interference between photons scattering from different atoms [3][4].…”
