Abstract: In summary, to simplify operation of a medical image acquisition system, it is proposed that the image acquisition system continuously monitors a current image acquisition situation and assigns at least one new function to at least one, preferably manual, operating element, which is adapted to a detected new image acquisition situation, in response to a change in the image acquisition situation, to the extent that said newly assigned function is adjustable and/or operable with the at least one operating element. To this end, the image acquisition system can detect the change in the image acquisition situation using predefined parameters by means of sensors and/or through communication with peripheral units and/or preferably through image analysis of an image sequence which is recorded with an image sensor of the image acquisition system.

Abstract: A nozzle and a process suitable for dispensing liquid foamable products, particularly useful with carbon dioxide blowing agents, the nozzle comprising a tubular exit zone having an inlet and an outlet; the tubular exit zone having an inner wall surface defining a passageway for dispensing having a centerline axis; the tubular exit zone further having a plurality of vanes attached to the inner wall surface parallel to the centerline axis with the vanes extending radially into the passageway for dispensing; the vanes having a length dimension that is the distance the vane contacts the inner wall surface parallel to the centerline axis, a thickness dimension that is the effective thickness of the vane at the inner wall surface perpendicular to the centerline axis, and a width dimension being the distance from the inner wall surface that the vane extends into the passageway for dispensing; and wherein the vanes do not connect or touch at the centerline of the passageway for dispensing.
