Abstract
Official abstract text for this publication.
A beam data processing apparatus has a plurality of channel data conversion units that convert a plurality of analogue signals outputted from a position monitor into digital signals, a position size processing unit that calculates a beam position, based on voltage information items obtained through processing by the plurality of channel data conversion units, an abnormality determination processing unit that determines the beam position and generates a position abnormality signal, and an integrated control unit that controls the plurality of channel data conversion units in such a way that while a beam is stopped at an irradiation spot, digital signal conversion processing is implemented two or more times; the channel data conversion unit has a plurality of A/D converters, a demultiplexer that distributes analogue signals, and a multiplexer that switches respective digital signals processed by the A/D converters so as to output them to the position size processing unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A beam data processing apparatus that performs calculation processing of a state of a charged particle beam that has been accelerated by an accelerator and has been scanned by a scanning electromagnet in a particle beam therapy system for irradiating a diseased site, the beam data processing apparatus comprising: a plurality of channel data conversion units that perform A/D conversion processing in which each of a plurality of analogue signals, outputt…
