    • A light device includes a shielding plate (2) having an opening (2H) of a rectangular cross-sectional configuration and placed over an optical window retainer (15). The shielding plate (2) is placed so that an opening wall surface (2HS) thereof is positioned on an optical path (Zr(x)) of light emerging from an optical window (14) at a usable angle (&thgr;e) and that a half width (Xu) of the opening (2H) satisfies Xu=u/cot(&thgr;e)+t×sin(&thgr;e)/sgrt(ng2−sin2(&thgr;e))+s. The optical window retainer (15) is placed in a region outside a boundary line given as Zh(x)=±(1×tan(&thgr;e)(x±Xu)+u (plus (+) when x≦−Xu; minus (−) when x≧Xu) and also in aregion outside the optical path (Zr(x)). The light source device suppresses an uneven illuminance distribution of exposure light resulting from superimposition of light scattered from the opening wall surface of the optical window retainer upon the exposure light.
    • 光装置包括具有矩形横截面构造的开口(2H)的屏蔽板(2),并放置在光学窗保持器(15)上。 屏蔽板(2)被放置成使得其开口壁表面(2HS)位于从光学窗口(14)以可用角度(θe)出射的光的光路(Zr(x))上,并且 开口(2H)的半宽度(Xu)满足Xu = u / cot(θe)+ txsin(θe)/ sgrt(ng2-sin2(θe))+ s。 光学窗口保持器(15)放置在给定为Zh(x)=±(1xtan(θe)(x±Xu)+ u(+(x))处的边界线以外的区域,当x <= - Xu; - )当x> = Xu时),并且在光路外(Zr(x))的范围内,光源装置抑制由从光学窗口的开口壁表面散射的光的叠加产生的曝光光的不均匀照度分布 固定在曝光灯上。

    • A radiation control method includes: calculating degrees of similarity corresponding to matching target areas; calculating a specific image position where a specific image area corresponding to a maximum value of the degrees of similarity out of the matching target areas is positioned in a radiographic image; and calculating a drive amount with which a therapeutic radiation ray irradiation device is driven, based on the specific image position. Further, calculating one degree of similarity corresponding to one matching target region out of the degrees of similarity includes: referring to a template table in which the matching target areas are associated with sets of templates to calculate a set of templates corresponding to the one matching target area out of the sets of templates; and detecting, from the set of templates, a similar template most similar to a matching target image displayed in the one matching target area of the radiographic image.

    • A radiation therapy apparatus control method includes: calculating a plurality of degrees of similarity corresponding to a plurality of matching target areas based on a radiographic image; calculating a specific image position where a specific image area corresponding to a maximum value of the degrees of similarity out of the matching target areas is positioned in the radiographic image; and calculating a drive amount with which a therapeutic radiation ray irradiation device is driven, based on the specific image position. The operation of calculating the one degree of similarity corresponding to the one matching target region out of the degrees of similarity includes: referring to a template table in which the plurality of matching target areas are associated with a plurality of sets of templates to calculate a set of templates corresponding to the one matching target area out of the plurality of sets of templates; and detecting, from the set of templates, a similar template most similar to a matching target image displayed in the one matching target area of the radiographic image.
