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 a 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.

7. An operation method of a radiotherapy system, comprising:
-
calculating a target position based on a position of a specific part of a sample at a measurement time; and controlling a drive unit to drive a radiation irradiating unit which irradiates 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 a preparation period, and wherein when the control time is contained in a therapy period after the preparation period, said post-correction target position shows the target position. - View Dependent Claims (8, 9, 10, 11, 12)
