CONTROL APPARATUS OF RADIOTHERAPY SYSTEM AND OPERATION METHOD OF RADIOTHERAPY SYSTEM
First Claim
1. A control apparatus of a radiotherapy system comprising:
- an irradiation object detecting section configured to calculate a target position based on a position of a specific part of a sample at a measurement time; and
a swing position control section configured to control a drive unit to drive a radiation irradiating unit configured to irradiate a therapeutic radiation, such that said radiation irradiating unit turns to a post-correction target position at a control time after the measurement time,wherein said post-correction target position indicates a position nearer a position to which said radiation irradiating unit turns immediately before the control time rather than the target position, when the control time is contained in the preparation period, andwherein when the control time is contained in a therapy period after the preparation period, said post-correction target position shows the target position.

Abstract
A control apparatus of a radiotherapy system of the present invention includes an irradiation object detecting section configured to calculate a target position based on a position of a specific part of a sample; and a swing position control section configured to control a drive unit to drive a radiation irradiating unit which irradiates a therapeutic radiation, such that the radiation irradiating unit directs to a post-correction target position at a control time after the measurement time. The post-correction target position indicates a position near a position to which the radiation irradiating unit directs rather than the target position in the preparation period before a therapy period, and the target position in the therapy period.
