PROBLEM TO BE SOLVED: To provide radiographic equipment for doctors round visits which permits noise of the equipment to be restrained by rotating the anode of an X-ray tube at low speeds by operating it in a silence mode when the silentness of the equipment is required.SOLUTION: The radiographic equipment for doctors round visits includes a traveling cart 1, the X-ray tube supporting portion attached to the traveling cart, an anode rotating X-ray tube 3 supported by the X-ray tube supporting portion, an anode driving control portion 8 supplying a voltage to the anode rotating mechanism of the X-ray tube and controlling the rotation of the anode, a high-voltage generator 9 mounted on the traveling cart and applying a high voltage to the X-ray tube, and an X-ray detector provided on the traveling cart and detecting an X-ray transmission image from a subject. The anode driving control portion can change the rotating speed of the anode 4 of the X-ray tube during X-ray irradiation, and operates the anode of the X-ray tube in the silence mode in which it rotates at low speeds when it is judged that a silent operation is required on the basis of preset radiographic conditions or when a silent action command is input.COPYRIGHT: (C)2009,JPO&INPIT【課題】装置の静粛性が要求される場合に、X線管の陽極を静粛モードで動作させて低速回転させることで、装置の騒音を抑制できる回診用X線撮影装置を提供する。【解決手段】移動用台車1と、移動用台車に取り付けられたX線管支持部と、X線管支持部に支持された陽極回転型X線管3と、X線管の陽極回転機構に電圧を供給し、陽極の回転を制御する陽極駆動制御部8と、移動用台車に搭載され、X線管に高電圧を印加する高電圧発生装置9と、移動用台車に備えられ、被検者からのX線透過像を検出するX線検出器を有する。陽極駆動制御部が、X線照射時のX線管の陽極4の回転速度を変更し得るようになっていて、予め設定された撮影条件に基づき静粛動作が要求されると判定したとき、または、静粛動作命令の入力を受けたとき、X線管の陽極を、低速度で回転する静粛モードで動作させる。【選択図】図2
