  • Patent number: 8576087
    Abstract: A radiation imaging system includes a radiation imaging cassette and a console device. A communication mode between the cassette and the console device is switchable between a wired mode and a wireless mode. Due to shortage of a battery of the cassette, the communication mode is switched to the wired mode to start charging the battery and send image data from the cassette to the console device through a cable. The console device has first and second judging sections. The first judging section judges whether or not a charge level of the battery exceeds a predetermined threshold value. The second judging section judges whether or not radiography is in progress. If it is judged that the charge level of the battery exceeds the predetermined threshold value and the radiography is not in progress, a window that indicates permission for switching to the wireless mode is displayed on a monitor.

  • Publication number: 20130284951
    Abstract: A multi-leaf collimator includes leaf drives and two sets of displaceable leaves arranged side by side and facing each other to impress a high-energy beam with the shape of an irregularly formed treatment object. Each of the leaves assumes a position oriented along the shape of the treatment object by means of a leaf drive and each are equipped with a gear rod-like drive engagement in the direction of the displacement. A leaf-side pivotable gear segment is located, together with a motor-side gear segment, on a segment disk that engages with the gear rod-like drive engagement. A pinion drivable by a motor engages with the motor-side gear segment. The segment discs are arranged side by side for each set of leaves as a package on one axis. The motor-side gear segments of two segment disks located next to each other are staggered so that they will not abut each other.

    Abstract: To include a step of installing a hollow container (1) at a predetermined portion of an object to be shielded (100), a step of feeding fluid into the container (1) via a hose (22) by a fluid feeding unit (2), and a step of transporting and filling a granular shielding material into the container (1) via the hose (22) by supplying the shielding material to the fluid by a shielding-material supply unit (3). With this arrangement, because a shielding material is fed into the container (1) together with the fluid and filled therein at a remote place from the object to be shielded (100), a worker does not need to approach the object to be shielded (100). Further, because a shielding effect is improved by the granular shielding material, an amount of radiation to the worker can be reduced easily and sufficiently.

  • Patent number: 8569713
    Abstract: A column assembly of a radionuclide generator includes a column that retains a parent radionuclide that spontaneouosly decays to a relatively short-lived daughter radionuclide. A fluid path extends from an inlet port to the column and then to an outlet port and allows daughter radionuclide to be eluted from the radionuclide generator for use. Improved retention of parent radionuclide in the column is accomplished by preventing fluid from entering the flow path in a liquid state, such as during sterilization. Proper column chemistry is also promoted by preventing excess moisture from coalescing in the column, which may promote a higher and/or more reliable yield of daughter radionuclide from a radionuclide generator.

    Abstract: A composite infrared target simulation display system for field testing of infrared (IR) search and track, guidance and general sensory systems. The system includes one or more tileable emitter arrays scalable without systemic size limitation. The emitter arrays are square faced tiles housing power and control electronics to autonomously display a stored infrared test image according to parameters distributed by a control host and a timing signal. A face of the emitter array is divided into regularly spaced pixel positions, each made up of multiple IR emitters operating in differing regions of the IR band to display an image. Multiple emitter array tiles are joined to form a complete system. Each emitter of each pixel position is individually addressable to be individually controllable with respect to emittance state for displaying an image. Multiple images may be sequentially displayed to replicate a simulated target signature in motion.

A vortex beam generator for imparting orbital angular momentum to the input particle beam. An electromagnetic field generator generates a transverse magnetic field, space-variant and symmetric with respect to the axis of the input particle beam, in such a way as to change the spin of the particles and attach thereto different values of orbital angular momentum in dependence on their input spin values. A beam component separating group spatially separates the particles in dependence on their orbital angular momentum values, in such a way as to obtain the at least partially spin polarized output particle beam.

  • Publication number: 20130161509
    Abstract: The invention relates to a method for identifying gases, which are ionized and the drift times of the positive and negative product ions through drift spaces are measured and the measured drift times are evaluated, wherein for measuring the drift times the product ions are accelerated to drift velocities by a resulting electrical field. It is provided that the positive and negative product ions move synchronously and in parallel in the same direction. The invention further relates to a device for identifying gases, which includes at least two drift tubes, wherein each of the drift tubes has at least one respective detector for detecting product ions. For this purpose, at least two drift tubes are arranged in parallel next to each other and are delimited, on one hand, by a common inlet system and, on the other hand, by at least one detector.
