    摘要: An apparatus includes a scanner (102, 104) and a scanning motion monitor (100). A motion modeler (116) uses data from the scanning motion monitor (100) and the scanner (102, 104) to generate a motion model which describes motion of a region of interest of an object. A treatment planner (112) uses image data from the scanner (102, 104) to establish a treatment plan for the object. A treatment device 114, which operates in conjunction with a treatment motion monitor (108), uses the motion model to compensate for motion of the object during application of the treatment.

    摘要: An imaging system (10) comprises a data device (30), which controls radiation data acquisition from a subject positioned in an examination region (18) for an examination. A rebinning processor (40) bins the acquired data periodically into a histogram (42). A transform (70) transforms the histogram (42) into individual independent or uncorrelated components, each component including a signal content and a noise content. A stopping determining device (52) compares an aspect of at least one selected component to a predetermined threshold (TH) and, based on the comparison, terminates the data acquisition.

    摘要: An apparatus for treating an aqueous medium containing microorganisms comprises an intake for receiving the aqueous medium containing microorganisms. A pressure differential inducer is associated to the intake so as to receive the aqueous medium containing microorganisms with a desired level of gas saturation. The pressure differential inducer is actuatable to expose the aqueous medium containing microorganisms with a desired level of gas saturation to accelerations so as to cause cell wall rupture of the microorganisms. An outlet is associated with the pressure differential inducer for outletting the treated aqueous medium containing ruptured microorganism cells and contents. The treated aqueous medium containing ruptured cell wall of the microorganisms is disposed of and/or recycled.
