The visual and quantitative results of the validation process showed an overall good correlation between simulated and experimental images and show the potential of this platform for research in phase contrast x-ray imaging of the breast. The software platform was used to design computational phantoms that mimic those used in the experimental study and to generate x-ray images in absorption and phase contrast modes. To test and validate the platform, several phantoms differing in their complexity were constructed and imaged at 25 keV and 60 keV at the beamline ID17 of the European Synchrotron Radiation Facility. Projection images are generated in an in-line acquisition geometry. These modules were updated to take into account the refractive index for phase contrast imaging as well as implementation of the Fresnel-Kirchhoff diffraction theory of the propagating x-ray waves. The software platform, developed at the Technical University of Varna on the basis of a previously validated x-ray imaging software simulator, comprises modules for object creation and for x-ray image formation. To present and validate a computer-based simulation platform dedicated for phase contrast x-ray breast imaging research. Furthermore, it could be used to classify images including from other anatomical parts such as breast or lung, after proper re-training of the classification algorithms.Ī software platform for phase contrast x-ray breast imaging research.īliznakova, K Russo, P Mettivier, G Requardt, H Popov, P Bravin, A Buliev, I The proposed software platform has a friendly and clear graphical user interface and could be a useful second-opinion tool to a dermatologist. The automated selection of a ROI includes filtering for smoothing the image and thresholding. Furthermore, it provides suitable tools for selecting, either manually or automatically, a region of interest (ROI) on the image. The platform supports image formats such as Windows bitmaps, JPEG, JPEG2000, portable network graphics, TIFF. The platform provides the capability for reading a file that contains a dermatology image. The purpose of this paper is to present a software platform developed in Python programming environment that can be used for the processing and analysis of dermatology images.
