摘要： A scanning method which is a method of identifying a change in the density of an object includes arranging a source of ionizing radiation and an array of radiation detectors Dn, where n is an integer from 1 to N, capable of detecting the radiation in such a way that radiation counts are counted by the detectors as the source and detectors are rotated around the object and normalized counts values are collated in a matrix such that a pattern may be detected within the matrix from which the presence of a change in the density of the object at a location lying on at least one of the radiation paths may be inferred.

摘要： A subsea apparatus (1, 201) is disclosed. The subsea apparatus (1, 201) comprises a first part (2, 202) and a second part (3, 203) rotatably mounted on the first part (2, 202). The second part (3, 203) comprises electrically powered components (16). A motor (8, 208) is mounted on the first part (2, 202) and configured to drive rotation of the second part (3, 203) relative to the first part (2, 202). The apparatus also comprises a generator (12, 212) mounted on the second part (3, 203) such that rotation of the second part (3, 203) relative to the first part (2, 202) drives the generator (12, 212) to generate power for the electrically powered components (16). A method of providing power to a rotating part of a subsea apparatus (1, 201) is also disclosed.

摘要： An apparatus for scanning a structure to detect density differences between different structure parts, the apparatus includes a source of gamma radiation, a plurality of first detectors arranged to detect radiation emitted by the source along a plurality of respective first paths, a plurality of second detectors arranged to detect radiation emitted by the source along a plurality of respective second paths. Each first and second path is substantially aligned with a respective radius of a circle centered on the source, and an angular separation between at least two neighbouring first paths is S. The first and second detectors and the source are arranged for rotation in a fixed relationship with respect to each other, about an axis of rotation located between the source and detectors, wherein the axis of rotation is substantially orthogonal to the circle. An asymmetric collimator block directs gamma radiation from the source to the detectors.
