Abstract: An optical coherence tomography microscopy apparatus (1) is presented for detecting a three-dimensional image of an optically translucent or reflective sample object (OS), the apparatus comprising an interferometric optical setup including a photo sensor unit (20). A sense signal Si from the photo sensor unit (20) is detected using a detection reference signal. The detection reference signal is derived from a signal indicative for a relative displacement of the sample object (OS) with respect to a reference object.

Abstract: A bogie (6) comprises a bogie frame (7). The bogie frame (7) is mounted on bearings (7b) via a first spring device (7a). A wheelset shaft (8) is mounted in the bearings (7b). A wheelset drive (9) concentrically surrounds the wheelset shaft (8) and acts thereupon. The wheelset drive (9) is spring-mounted on the bearings (7b) by means of a second spring device (16) exclusively associated with the wheelset drive (9). A two-level clutch (15) is arranged between the wheelset drive (9) and the wheelset shaft (8).

Abstract: A bevel gear drive includes an input shaft which includes an input bevel gear and has an input interface at one shaft end thereof. The input shaft is arranged vertically in operation and supported by a bearing at a side of the input bevel gear facing away from the input interface. An output shaft includes an output bevel gear in direct meshing engagement with the input bevel gear, with the output shaft being overhung-mounted and having an output interface at one shaft end thereof which faces away from the output bevel gear. Both, the input shaft and the output shaft are mounted in a drive housing.

Abstract: A contrast agent useful for imaging a sample comprising a suspension in a medium acceptable for imaging (a) particles of a contrast agent possessing paramagnetic characteristics and (b) particles of a contrast agent possessing diamagnetic characteristics. Also disclosed is a method of imaging a sample which comprises introducing into the sample the above-described contrast agent and generating a substantially artifact-free image thereof. The combination of diamagnetic barium sulfate and superparamagnetic iron oxide (SPIO) in one suspension produces a macroscopic cancellation of positive and negative magnetic susceptibility components which eliminates susceptibility artifacts even with gradient echo pulse sequences. The relaxation properties which make the SPIO suspension a useful negative contrast agent are retained.
