摘要： The present invention provides a way of placing a physical layer device into a standby mode. After a link is established between multiple devices, a determination is made whether the device has data to transmit or whether a standby request was received from a link partner. If a standby request was received or the device has no data to transmit, standby mode is entered. In standby mode, unneeded circuitry is powered down. A transmitter in a channel and a receive path in a separate channel remain powered. While operating in standby mode, the PHY layer continuously transmits a standby code on the one or more channels that are not powered down. Standby mode is discontinued when a transceiver has data to transmit or when energy is detected on the powered down channels. Standby mode is also discontinued when no standby code is received, indicating a disconnect between devices.

摘要： Aspects of a method and system for Ethernet Switching, Conversion, and PHY optimization based on link length in Audio/Video Systems are provided. In this regard, the length of a link over which a first communication device communicates with a second communication device may be determined and Ethernet PHY's residing in the communication devices may be configured based on the determination. One or both of the communication devices may comprise an Ethernet switch operable to switch packetized audio and/or video content. The packetized audio and/or video may be switched between the configured Ethernet PHY and one or more other Ethernet PHYs. Audio and/or video data may be received via the one or more corresponding Ethernet PHYs, the received audio and/or video data may be reformatted to be compatible with an audio and/or video interface, and the reformatted audio and/or video data may be transmitted via the audio and/or video interface.

摘要： It is desirable to achieve a co-incident investigative kV source for a therapeutic MV source—a so-called “beams-eye-view” source. It has been suggested that bremsstrahlung radiation from an electron window be employed; we propose a practical structure for achieving this which can switch easily between a therapeutic beam and a beam-eye-view diagnostic beam capable of offering good image resolution. Such a radiation source comprises an electron gun, a pair of targets locatable in the path of a beam produced by the electron gun, one target of the pair being of a material with a lower atomic number than the other, and an electron absorber insertable into and withdrawable from the path of the beam. In a preferred form, the electron gun is within a vacuum chamber, and the pair of targets are located at a boundary of the vacuum chamber. The lower atomic number target can be Nickel and the higher atomic number target Copper and/or Tungsten. The electron absorber can be Carbon, and can be located within the primary collimator, or within one of a plurality of primary collimators interchangeably locatable in the path of the beam. Such a radiation source can be included within a radiotherapy apparatus, to which the present invention further relates. A flat panel imaging device for this source can be optimised for low energy x-rays rather than high energy; Caesium Iodide-based panels are therefore suitable.

摘要： Embodiments of the present invention provide a method of pre-approving a range of hypothetical spatial variations of the target whilst an initial treatment plan is generated. This allows the treatment plan to be later adapted to account for spatial variations of the target region falling within those pre-approved ranges, without going through time-consuming steps of quality assurance on the adapted plan.

摘要： The present invention therefore provides a method for the analysis of radiographic images, comprising the steps of acquiring a plurality of projection images of a patient, acquiring a surrogate signal indicative of the location of a target structure in the patient, reconstructing a plurality of volumetric images of the patient from the projection images, each volumetric image being reconstructed from projection images having a like breathing phase, identifying the position of the target structure such as a tumour in each volumetric image, associating a surrogate signal with each of the projection images, and determining a relationship between the surrogate signal and the position of the target structure. Multiple projection images having a like breathing phase can be grouped for reconstruction, to provide sufficient numbers for reconstruction. The analysis of the multiple values of the surrogate associated with each breathing phase can be used to determine the mean surrogate value and its variation. Multiple values of the surrogate signal associated with the same nominal breathing phase can be used to determine a mean value of the surrogate signal for the target position associated with that phase and a variation of the value of the surrogate signal for the target position associated with that phase. The breathing phase of specific projection images can be obtained by analysis of one or more features in the images, such as the method we described in U.S. Pat. No. (7,356,112), or otherwise.

摘要： Flat panel images obtained during concurrent radiotherapy typically suffer from artefacts that relate to the pulses of MV energy. For a radiotherapeutic apparatus comprising a pulsed source of therapeutic radiation, a detector comprising control circuitry, an array of pixel elements, each having a signal output and an ‘enable’ input and being arranged to release a signal via the signal output upon being triggered by the enable input, and an interpreter arranged to receive the signal outputs of the pixel elements, the interpreter having a reset control, there are advantages in the control circuitry being adapted to reset the interpreter after a pulse of therapeutic radiation, prior to enabling at least one pixel of the array. Alternatively, the control circuitry can prompt a plurality of pulses by the pulsed source and then enable a plurality of pixels of the array. In effect, the therapeutic pulses are grouped into a short flurry of pulses. It is therefore preferred that the plurality of pixels comprises substantially all the pixels of the array.

摘要： Realtime beam shape adjustment in response to (for example) online CT scanning of a patient during treatment is assisted by the radiotherapy apparatus comprising a source adapted to emit a beam of therapeutic radiation, a collimator for delimiting the radiation beam, the collimator comprising a plurality of leaves arranged alongside each other and be moveable longitudinally so that the tips of the leaves define a variable edge of the collimator, the leaves being mounted on a support that is moveable laterally with respect to the leaves. In this way, movements of the tumour that are perpendicular to the direction of leaf motion can be accommodated by simply moving the collimator bodily so as to accommodate this. It is preferred that the apparatus also includes a control means adapted to receive information as to the location of the target volume, and, on the basis of that information, control the longitudinal positions of the leaves and the lateral position of the support. It is also preferred that the support tilts as it moves laterally along a path. This can be achieved, by example, by bearings that are moveable on suitable guides, or by mounting the support on a plurality of pivot arms of unequal lengths. The lengths of such pivot arms can be adjusted as necessary.
