Abstract: A medical imaging device for use in imaging a subject using both gamma rays and light rays emanating from the subject, the device comprising: separation means to separate gamma rays and light rays emanating from the subject into a gamma ray channel comprising gamma rays and a light ray channel comprising light rays; first sensor means arranged to receive and detect gamma rays from the gamma ray channel and to generate first signals for use in forming a first image of the subject; second sensor means arranged to receive and detect light rays from the light ray channel and to generate second signals for use in forming a second image of the subject; wherein the first sensor means and the second sensor means are arranged to receive gamma rays and light rays, respectively, which propagate from the subject upon substantially coincident paths.

Abstract: A liquid management system for supplying or receiving liquid at a controlled pressure, comprising: a closed reservoir having an inlet for receiving liquid from a first remote location and an outlet for supplying liquid to a second remote location; and a pumped outlet disposed in the reservoir and arranged to remove liquid and gas contained within the reservoir, the pumped outlet being disposed such that the level of liquid in the reservoir can be maintained at a constant height.
