20090257529 | LOW POWER, INTEGRATED RADIO TRANSMITTER AND RECEIVER - A low power (optionally, self-powered) integrated transceiver using on-chip antennas is provided. The transmitter and receiver utilize phase-locked loops (PLLs) which initially, in a closed-loop state, pre-tune (i.e. phase-lock) voltage controlled oscillators (VCOs) before opening the loops to allow them to transmit and receive data.

20090257561 | GENERAL IMAGING SYSTEM - To automate positioning operation of an X-ray tube so as to reduce the inspection time.

20090257562 | Mammography x-ray homogenizing optic - A conical anode X-ray source with a spot size approximately one tenth of the size of existing mammography devices. The source produces the same or higher radiance than the prior art. It also produces almost no high-energy Bremstrahlung. The electron beam is directed into a conical anode so that it strikes the reflecting surface at an angle which produces total internal reflection. The X-rays emitted via the reflection would ordinarily exit the small end of the conical anode in a diverging conical pattern—producing an undesirable “ring” configuration at the image plane. A homogenizing optic is therefore preferably added to the small end of the conical anode. The homogenizing optic is sized to reflect the X-rays emerging from the conical anode and thereby create a uniform “spot” source at the far end of the homogenizing optic. | 2009-10-15 |
20090257563 | Approach and device for focusing x-rays - In the present invention we propose a new device for x-ray optics which is an analogy to the zone plates but working for higher x-ray energies. This is achieved by using both refraction and diffraction of the x-rays and building the new device(s) in a three dimensional structure, contrary to the zone plates which are basically a two dimensional device. The three dimensional structure is built from a multitude of prisms, utilizing both refraction and diffraction of incoming x-rays to shape the overall x-ray flux. The result will be the first ever device achieving true two dimensional focusing in the x-ray energy range usually employed in medical imaging and may be used in a wide area of applications in this field and in other fields of x-ray imaging. The device will further be fairly straight forward to produce in large volumes. | 2009-10-15 |
20090257564 | RADIATION IMAGE CAPTURING SYSTEM - A radiation image capturing system detects the position of a radiation detecting cassette disposed below a patient and the position of a radiation source for emitting a radiation, based on the differences between the propagation times of radio waves emitted from an antenna device to an image capturing apparatus and the radiation detecting cassette. Based on the detected positions, the relative positions of the image capturing apparatus and the radiation detecting cassette are calculated, and then compared with each other by a position determining unit to judge how the image capturing apparatus is positioned with respect to the radiation detecting cassette. If the image capturing apparatus is not positioned in head-on facing relation to the radiation detecting cassette, then a warning is issued, and an actuating mechanism moves the image capturing apparatus to an appropriate position. | 2009-10-15 |
