20110121763 | Linear Accelerators - We propose that during the factory testing of the linac, rather than simply confirming that the beam falls within the permissible ranges set out in the standard, the beam is in fact adjusted towards a standard signature. A new (or existing) linac could then be paired to a new linac, or to an existing linac, such as one that it is to operate alongside or one that it is to replace. Treatment plans would then be transferable between such pairs of linacs. In addition, the standard signature to which the linacs were approximated could be placed towards the centre of the permitted ranges, to produce linacs that were more reliable over the very long term. This requires a linac that has automatically adjustable parameters, so that a suitable programmed computer is able to monitor the output of the linac and adjust its operating parameters.

The power management unit is automatically adjusted to the output resistance of a power source (including interconnect resistance). The invention maximizes the time and hence the power transferred from a power management unit to the system (including the battery, in case of battery operated systems). The input current is reduced thus increasing the input voltage in case of a high voltage drop across the internal resistance including interconnections between power source and power management unit. | 2011-05-26 |
