Abstract: This radiation therapy device controller selects, for a plurality of body motion phases, computed tomography image data obtained which shows a diseased portion, and generates, for each rotation angles of a ray source and a sensor array, a reconstructed image. The control device generates a radiation projection image which shows the diseased portion when the radiation is radiated if the rotation angle is a predetermined rotation angle, compares the reconstructed image of each of the plurality of body motion phases with the radiation projection image, and determines a body motion phase indicated by a reconstructed image in which a difference is small, to be a current respiratory phase. As a result, a position of the diseased portion calculated for the computed tomography image data in the computed tomography image data group of the respiratory phase in advance is identified to be a current position of the diseased portion.

The sound insulating face is obtained by applying an adhesive allover a surface of the sound insulating face that makes contact with the honeycomb material and pressing opposite edges of cell walls of the honeycomb material against the sound insulating face so that the opposite edges bite into the surface, having the adhesive, of the foam.

Abstract: [Problem to be Solved] In a laminated material based on a honeycomb material, there has been such a problem that the bonding between a honeycomb material serving as a base and two face materials between which the honeycomb material is sandwiched requires bonding between planar members having great rigidity with a high degree of planar accuracy and honeycomb members that are linear and not completely flat, thus making it to obtain a great deal of bonding force. [Solution] A honeycomb panel laminate includes a sound absorbing face, a sound absorbing layer, and a sound insulating face. The sound absorbing face is made of a foam. The sound absorbing layer is composed of a honeycomb material and a layer obtained by filling spaces with a hard foam material.
