Abstract: This invention is related to a supervision system that monitors automated movements performed by components of an medical imaging modality, in order to ensure that the moving components behave as expected, while identifying at the same time potential conflicts with (alien) objects or persons in the medical scene. The invention is based on the analysis of differences between measured distance data obtained by a detector that is mounted on the medical imaging modality, and a calculated virtual model of the geometric state of the modality components in the medical scene.

Abstract: A method and system for accurately determining the SID (source-image-distance) in a radiography configuration with a wireless radiographic detector, and a method and system for determining the thickness of a patient in a radiography configuration. The method for determining the SID is based on a method to accurately determine distances between a set of generator arrays and sensor arrays. The generator arrays and sensor arrays are preferably orthogonally arranged magnetic field generators and sensors that allow measurements of distances without being affected by presence of human tissue between the generator and sensor arrays.

Abstract: A phase contrast imaging (PCI) method in which, instead of using an analyzer grid, detector pixels are grouped and only a part of the total pixels are used to calculate a phase contrast image. In second, third, etc. steps, the pixels which were not used in the previous recalculation are used additionally to recalculate second, third, etc. phase contrast images. Finally the different phase contrast images are fused to result in a full image.
