However, direct background subtraction inevitably overcorrects the signal as it does not take into account the attenuation by the sample. Other traditional background removal methods, such as the rolling ball technique, can separate sharp diffraction peaks of crystalline materials from their background. These methods are unsuitable for biological tissue, which is amorphous and does not have sharp diffraction peaks. This technical note proposes a novel method that combines peak fitting and experimental results to estimate the background for 2D XRD signals. date: 2018-03-21 date_type: published official_url: http://dx.doi.org/10.1088/1361-6560/aaac9e oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1534083 doi: 10.1088/1361-6560/aaac9e lyricists_name: Griffiths, Jennifer lyricists_name: Speller, Robert lyricists_name: Zheng, Yi lyricists_id: JAGRI83 lyricists_id: RDSPE08 lyricists_id: YZHEN75 actors_name: Zheng, Yi actors_name: Allington-Smith, Dominic actors_id: YZHEN75 actors_id: DAALL44 actors_role: owner actors_role: impersonator full_text_status: public publication: Physics in Medicine & Biology volume: 63 number: 6 event_location: England issn: 1361-6560 citation: Zheng, Y; Speller, R; Griffiths, J; (2018) A novel method to remove the background from x-ray diffraction signal.
