Abstract: Emission event data of an object of interest is acquired with a detector comprising a plurality of rings defining corresponding slices. Also, an amount of motion for each of a plurality of segments is determined with one or more processing units, wherein each segment corresponds to less than an axial field of view (AFOV) of the detector. Further, motion mitigation is performed for segments for which the amount of motion satisfies a threshold to provide motion mitigated data, and not performed for segments for which the amount of motion does not satisfy the threshold to provide non-mitigated data. An image is reconstructed using the motion mitigated data and the non-mitigated data, and the image is displayed on a display.

Abstract: Apparatus is provided for plasma treating a substrate. This has a chamber (2) and a plasma generator (4) which forms a plasma from one or more gases flowing within the chamber so as to produce one or more species for interacting with a substrate (8) placed within the chamber. A guide (12) is provided for directing the gas flow containing the species towards the substrate (8). When in use, the width of the plasma is greater than that of the substrate by an amount defining an outer region of plasma. The guide is adapted to direct the species from at least substantially all of the outer region of the plasma towards the substrate. A corresponding method of plasma treatment is also disclosed.
