Title: 放射線装置
IPC: A61B6/00
Filed: 2015-12-28
Abstract: この発明の放射線装置では、時系列（複数フレーム）の特徴点としてマーカの位置に基づいて、当該フレームのマーカの各々の表示位置を順次に決定するので、動く対象物を適切な位置・方向・大きさに設定して表示することができる。また、複数のマーカを抽出することで対象物の方向および大きさの情報も保持され、対象物の近位・遠位の区別やデバイス（例えばステント）の長さが画像から直感的にわかるという効果をも奏する。また、複数のマーカの位置および複数の表示位置を用いて位置合わせを行うので、最終的に表示される補正画像自身も正確な位置・方向に設定することができる。

Abstract: The present invention addresses the problem of a conventional V2X communication system that, because vehicle information received from each vehicle is relayed from a base station to all vehicles in an area, unwanted transmission to vehicles that do not require the vehicle information occurs, resulting in an increase in communication traffic. According to the present application, vehicle information is transmitted to another vehicle (20) via a base station (30) only when it is determined that, on the basis of information carried by a vehicle (10) or the base station (30) pertaining to an area for which direct transmission or reception is difficult, it is difficult to perform direct transmission of vehicle information to the other vehicle (20) or direct reception of vehicle information transmitted from the other vehicle (20).

Abstract: An objective optical system (43) is provided with: a reflection surface (RS1) that reflects light beams traveling toward a sample (SP); a reflection surface (RS2) that reflects, toward the sample (SP), the light beams reflected by the reflection surface (RS1); and a transmission portion (TS) that is provided on the optical paths of the light beams reflected by the reflection surface (RS2) and that has a liquid contact surface which is in contact with a liquid (WT) interposed between the sample (SP) and the objective optical system, the liquid contact surface being formed so as to be substantially orthogonal to the optical paths of the light beams reflected by the reflection surface (RS2).
