    • 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.

    • Stereoscopic display with high definition compared with in the past may be easily realized. A lenticular lens 2 is disposed such that a longitudinal direction of each cylindrical lens 2A is parallel to an axis in a vertical direction Y of a two-dimensional display section 1. In addition, a plurality of beams corresponding to a plurality of view angles are radiated into a space by means of surface segmentation at a time, and a relative positional relationship between each cylindrical lens 2A and each pixel of the two-dimensional display section 1 is periodically changed, so that a radiation direction of display image light from one pixel through each cylindrical lens 2A is periodically displaced. Images corresponding to one frame of a three-dimensional video image are time-divisionally displayed for each pixel of the two-dimensional display section 1, and a timing of time division display of the two-dimensional display section 1 and a timing to change the relative positional relationship by displacement means are controlled to be synchronized with each other. Thus, stereoscopic display using a combination of a surface segmentation method and a time division method is performed, and consequently stereoscopic display with high definition compared with in the past is realized.
    • 与以往相比,具有高清晰度的立体显示可以容易地实现。 双凸透镜2设置成使得每个柱面透镜2A的纵向方向平行于二维显示部分1的垂直方向Y上的轴。另外,对应于多个视角的多个光束是 通过一次的表面分割辐射到空间中,并且每个柱面透镜2A与二维显示部分1的每个像素之间的相对位置关系周期性地改变,使得来自一个像素的显示图像光的辐射方向 通过每个柱面透镜2A周期性地移位。 对于三维视频图像的一帧对应的图像对于二维显示部分1的每个像素进行时分显示,并且二维显示部分1的时分显示定时和改变 通过位移装置的相对位置关系被控制为彼此同步。 因此,执行使用表面分割方法和时分方法的组合的立体显示,因此实现了与过去相比具有高清晰度的立体显示。
