Title: Method of processing seismic data
Inventor: HOOP MAARTEN VALENTIJN DE
IPC: G01V1/28
Filed: 1995-06-09
Abstract: A method is provided for processing seismic data samples obtained from seismic signals propagating in an anisotropic medium. The data samples are associated with scattering angles and azimuth at each migration dip at each image point of the medium. An inverse operator is then applied to the samples so as to provide intermediate anisotropic elastic parameter combinations for each migration dip at each point of the medium. The inverse operator comprises an inverse of a scattering function for variations in elastic parameters from a reference medium against scattering angle and migration dip. The intermediate anisotropic elastic parameter combinations are then migrated to their proper locations. The latter step is performed in accordance with a Generalised Radon Transform having specified Jacobians. <IMAGE>
Patent GB-2291306-A (GB)
Title: Image motion flag or vector filter
Inventor: JONES KENNETH STANLEY
IPC: H04N7/36
Filed: 1995-07-03
Abstract: Image motion flags or vectors are derived by subtracting a first image frame from the succeeding image and thresholding the absolute difference. To remove noise in the form of isolated motion flags from the resulting signal the input m is passed directly and via two pixel delays  delta pa1,  delta pa2 to the three inputs of an AND gate, the output of which is supplied directly and via two pixel delays  delta pb1,  delta pb2 to an OR gate to produce a replica of the input motion flag. If it is desired to accept image motion flags of only two pixels duration switches may set one input of the AND and OR gates to "1" and "0" respectively. Image motion may be classified into four classes - fully moving, covering, uncovering, static - by comparing the motion flags derived over two successive interframe periods; alternatively the motion class signals may provide the input to the motion flag filter. <IMAGE>

Patent GB-961066-A (GB)
Abstract: 961,066. X-ray examination apparatus. SIEMENS-REINIGER-WERKE A.G. Jan. 18, 1962 [Jan. 20, 1961], No. 1953/62. Heading H5R. An X-ray apparatus comprises an examination table, and also a patient-supporting trough rotatable about its longitudinal axis and mounted in a carrier frame; the trough and frame form an independent unit which can be wheeled about the floor separately from the table, but has means enabling it to be coupled to the table. As shown, the trough 16 is mounted on end bearings 17 on the supporting frame 18, so that it can be rotated about its longitudinal axis 17-17. The whole frame 18 itself is guided for longitudinal displacement by sleeves 19, such displacement being effected by a spindle drive 20 operated by a handle 21. The sleeves 19 are connected by a linkage 22 to a square frame 23 having rollers 24 at the corners. These rollers run on a transversely mounted ring 25 having a toothed periphery engaged by a motor-driven pinion 28, which can thus rotate the ring to effect corresponding swivelling of the trough 16. The whole forms an independent unit movable on travelling rollers 29. These run on rails 30 so that the whole unit can be moved up towards the X-ray table proper 1. This can swivel about a shaft 3 in supports 2, and is shown in a vertical position. The table plate 1b is slidable longitudinally in guideways 1a of table 1. Mounted on the table is the spot-film device 11 and the tube carriage 14. In addition to the usual controls, the spot-film device may also carry means for controlling the movements of the trough unit. When the unit has been moved right up to the table 11, it may be coupled to it by coupling elements 9 fixed to the frame 23. These enter into corresponding recesses 8 in the table rails 7. When the table plate 1b is moved upwards, the coupling elements 9 slide inside rails 7 until they come up against stop pins 31, after which the whole trough unit is lifted upwards. The arrangement obviates the necessity for transferring a patient from the trough support, where pre-treatment may be carried out, to the actual X-ray examination table.
