Abstract: A support apparatus for positioning a C-arm of a mobile x-ray apparatus in a horizontal position, enables a standard mobile x-ray device to perform CBCT acquisitions on an upright standing object or patient.

Abstract: The invention relates to a system for optical coherence tomography having an interferometer (20) which has a beam splitter (24), a reflector (25), an illumination arm (21), a specimen arm (22) and a reference arm (23). In order to increase the compactness of the system with at the same time a high image quality a specimen objective is provided in the specimen arm (22) of the interferometer (20) by means of which light is focussed into a focus lying in or on the specimen (1). Moreover, in the reference arm (23) of the interferometer (20) a reference objective is provided by means of which light is focussed onto the reflector (25). The optical properties of the specimen objective differ from the optical properties of the reference objective.

Abstract: The invention relates to a system and to a corresponding method for optical coherence tomography having a light source (15) for producing light (14), a first interferometer (10), a second interferometer (20) and an optical fiber (17) by means of which light emitted by the first interferometer (10) is conveyed to the second interferometer (20).
